The plastic pipe welding equipment market has experienced significant growth in Türkiye over the last decade. Housing projects, urban transformation works and the export-oriented construction sector have rapidly increased the demand for PPRC (Polypropylene Random Copolymer) pipe systems. Making the right choice among hundreds of different brands and models entering the market with this demand; It is becoming increasingly difficult for both construction contractors and individual plumbers.
In this guide, we discuss in detail the technical criteria that should not be ignored when purchasing a PPRC pipe welding set and practical tips filtered from industry experience. The field experience of Eral Makina, which has been exporting to more than 30 countries since 1993, forms the background of this information.
What is PPRC Pipe Welding Method?
PPRC pipe systems are joined by the socket fusion (electrofusion) method. In this method, the pipe end and the fitting are heated simultaneously and the polypropylene molecules begin to melt mutually; When two pieces are brought together, a permanent homopolymer bond forms during the cooling process. This ligament is, in theory, stronger than the nose; In other words, when welded correctly, the weakest point is not the connection, but the pipe itself.
In order for the socket fusion method to yield such solid results, several basic conditions must be met: the right temperature, the right time, a clean surface and the right equipment. Deviation in any of these conditions can lead to a combination that appears perfect in appearance but becomes problematic under pressure.
1. Wattage and Heating Stability
The wattage of the welding machine is the parameter that most users pay most attention to. However, making a choice just by looking at the wattage figure can be misleading. The main criterion is the heating temperature of the machine.is the stability— that is, how stable it can keep the 260°C set temperature under load (in contact with the cold pipe).
Low quality resistance systems experience a temperature drop when the die touches the cold pipe and take time to recover from this drop. The pipe surface, which cannot be heated sufficiently during this period, forms a weak bond due to partial fusion. In a quality machine, the resistance capacity and thermostat sensitivity minimize this temperature deviation.
- 800–1200W:Single resistance, home use, diameters between 20–32 mm
- 1500–2000W:Double resistance, professional use, diameters 16–63 mm
- 2000–3200W:Large diameter, construction site and industrial applications, 63–110 mm
Eral Makina pipe welding setsA double resistance thermoelectric heating system is standard. In this structure, if one of the two resistors fails while working, the machine can continue to operate with the remaining resistance — a critical uninterruptibility advantage in the field.
2. Roll Quality and PTFE Coating
Die ends are the surfaces where welding actually occurs. The pipe end and fitting become heated by contacting these surfaces. Any problems with this surface quality are directly reflected in the quality of the weld.
A quality sheet set should have three basic features:
- PTFE (Teflon) coating thickness and non-stickiness:Thin or low-quality PTFE coating begins to peel off after a few hundred joints and polypropylene residue begins to stick to the roll. Sticky sheeting not only spoils the next weld but also makes cleaning difficult.
- Plate thickness:The thicker the die material, the longer the heat is stored and the less the temperature drop at cold pipe contact. Plates below 15–20 mm are inadequate, especially in winter conditions.
- Diameter compatibility:Die ends are divided into standard (usually 20, 25, 32, 40, 50, 63 mm) and large diameter (75, 90, 110 mm) sets.Welding sheetsis mounted on the heating plinth with a screw connection; In some economical models, non-standard screw pitches are used, which makes it impossible to compatibility different brands of threads.
3. Set Includes: A Complete Collection of Tools
While many users think they are purchasing a welding set, they actually purchase only the welding machine. A field-ready kit should include:
- PPRC pipe cutter:It prepares the welding surface by cutting the pipe square and clean.Plastic pipe cuttersWe have prepared a separate guide on the subject.
- Pipe sharpener:Mandatory in multilayer pipes; It cleans the aluminum-lined surface and reveals a pure polypropylene surface.
- Die set (die inserts):It must meet the range of at least 20–63 mm.
- Carrying bag or metal box:It protects the die ends separately and prevents disintegration in the field.
- User manual and heating time table:In a standard manufacturer, this table is pasted on the inner surface of the bag or on the plinth.
Problems often seen in cheap sets: the plastic body of the scissors breaks in the first month, the die ends slip, the bag leaks and there is no heating table. Eral Makina sets are released containing all accessories approved by accredited field tests.
4. Thermostat Sensitivity and Digital Control
One of the most critical variables of weld quality is how accurately the roll temperature is maintained. Standard PPRC welding temperature should be within the range of 260°C ±10°C. Molecular diffusion cannot be completed in combinations below this range; When it is exceeded, polypropylene begins to degrade and the bond becomes mechanically weak.
Analog thermostats can drift over time — meaning the dial shows 260°C but the actual temperature may be 230°C or 290°C. Digital thermostat systems significantly reduce this risk. For professional use, models with digital temperature display and PID control should be preferred.
5. Security Features
According to the EN 60335-1 directive, heating devices must meet certain safety standards. Check the following security features before purchasing:
- Thermal overload protection:It automatically cuts off the circuit when the internal temperature of the machine exceeds the critical limit.
- Grounded plug and double insulation:Mandatory layers of safety against the risk of electric shock.
- Heat resistant cable sheath:Protection is required against hot threads or pieces of welded pipe that may fall on the cable in the field.
- CE mark and TÜV certificate:CE certificate is a minimum requirement for machines imported to Türkiye.Eral Makina certificationYou can get detailed information about.
6. Warranty, Spare Parts and Service
The total cost of ownership (TCO) of a power tool goes far beyond its purchase price. A machine for which spare parts cannot be found when the resistor or thermostat fails after the warranty period has expired is just a pile of metal.
There are many brands in the Turkish market that are not manufacturers or authorized importers. In these brands:
- Warranty claims may remain inconclusive despite invoice applications
- Spare parts required for resistance or thermostat repair may not be available
- Die ends cannot be changed over time because they are produced non-standard
Eral Makina eliminates these risks as a company that has been producing in Türkiye since 1993 and keeps its own spare parts stock. To reach the technical support lineour contact pageYou can visit.
Set Categories: From Residential to Construction Site
Choosing the right set largely depends on the usage scenario. Below are three basic user profiles and recommended set categories:
- Homeowner/minor maintenance:Less than 10 joins per month. 800–1000 W, 20–32 mm economical set. The most important criteria: ease of use and size.
- Residential plumber/craftsman:20–100 combinations per day. 1500 W double resistance professional set. The most important criteria: heat stability, PTFE quality and life of the scissors.
- Site team / contractor:100+ joints per day, diameters up to 63 mm. 2000–3200 W industrial set or butt welding systems for large diameters. The most important criteria: durability for continuous use and availability of spare parts.

Pre-Purchase Checklist
Answer these questions before making a purchasing decision:
- How many combinations do I make daily or monthly?
- What diameter range do I need to weld?
- Will the machine be used outdoors or in a cold environment?
- Can access to warranty and spare parts be provided?
- Is CE certificate available?
- Are there scissors, a pencil sharpener and a bag in the set?
When you come across a product that can provide satisfactory answers to all of these six questions, you will have made the right choice. Eral Makina technical team is always with you for more technical information and personalized suggestions.
Brand Selection: Price or Reliability?
The price range in the welding machine market is extremely wide. The difference between a model you can buy for 800 TL and a model worth 8,000 TL is seemingly only the brand name. But the real technical difference is much deeper.
Problems commonly seen in cheap models include: the plastic body deforms when exposed to heat due to its low melting temperature. Analogic thermostats may come from the factory with a deviation of ±20°C. Thread screws use non-standard connection, cannot be replaced. The manufacturer or authorized importer cannot be located in Türkiye.
Despite these sound features, there are quality Turkish-made brands available in the same price range. Eral Makina has been producing with ISO 9001 certified processes since 1993 and exports its CE certified products to more than 30 countries. Quality control and spare parts availability are offered together.
Standard vs. Certification — Which Matters?
The minimum reference point for welding machines entering the Turkish market is the CE mark. This marking certifies that the product complies with European Union directives — in particular the electrical safety directive EN 60335-1 and EN 60335-2-45.
However, CE is a mark that can be used fraudulently or misleadingly in the market. To verify reliability, see the following:
- Approved organization number:The CE marking must be accompanied by a 4-digit establishment number (e.g. CE 0197).
- Technical file:The manufacturer must be able to provide technical documentation upon request.
- TSE certificate:Additional assurance for the Turkish market.
- ISO 9001:Production quality management system certification guarantees factory quality control.

Steps of the Correct Set Purchasing Process
An ideal purchasing process follows this order:
- 1. Needs analysis:How often will you use it? What diameters will you work with? In an open or closed environment?
- 2. Budget determination:Consider the cost of the machine as well as maintenance, spare parts and service costs.
- 3. Technical comparison:Wattage, thread pitch, thermostat type, cable length, warranty period.
- 4. Reference check:Research real user feedback from the field for the brand you choose.
- 5. Purchase and testing:Test weld and get to know the machine in the first week after purchase.
Equipment You Should Take to the Field with the Welding Set
The resource set itself is not sufficient. Every professional should always have:
- Spare die inserts (minimum 20–32 mm set)
- Isopropyl alcohol and clean cloth
- Tape measure and pencil
- Pipe hanger and bracket set
- Manometer (for pressure test)
- Pipe overlap chart (heating time reference)
Every project completed with this equipment both improves the quality of the work and ensures customer satisfaction. For detailed product optionsEral Makina product page ve product catalogCheck it out.
What We Learned from User Experiences
During the production process of more than 30 years, we received feedback from many different user profiles. This feedback brought to the agenda some ignored criteria in resource set selection.
The most common complaints from contractors:The machine broke down in the field, spare parts could not be found. The solution to this complaint is to inquire about the authorized service network in Türkiye before purchasing. If there is no local service, no matter how cheap the machine is, it will be expensive in the long run.
The most common complaint from individual plumbers:The die ends peeled off in a few months. The main reason for this situation is improper cleaning using a metal spatula with PTFE coating quality. Ask about the PTFE coating thickness when choosing a set; Use only soft cloth for cleaning.
Experience of large construction site teams:The obvious superiority of double resistance models in terms of operating continuity has been proven in the field. Especially in winter conditions, a single resistance machine cannot compensate for heat loss.
Ways to Increase Plumbing Efficiency with the Resource Kit
- Preparation beforehand:Warm up the machine before going to the field; Do not weld immediately after starting work.
- Workflow planning:Reduce the number of sheet changes by grouping uniform joints.
- Team coordination:In teams of two, one person should warm up while the other prepares the next combination.
- Quality control:Cut and inspect a test weld every 50 joints.
Standard vs. Certification — Which Matters?
The minimum reference point for welding machines entering the Turkish market is the CE mark. This marking certifies that the product complies with European Union directives — primarily EN 60335-1 and EN 60335-2-45.
However, CE is a mark that can be used fraudulently or misleadingly in the market. To verify reliability, see the following:
- Approved organization number:There must be a 4-digit organization number next to the CE marking.
- TSE certificate:Additional assurance for the Turkish market.
- ISO 9001:Production quality management system certification guarantees factory quality control.
