Pipe Welder 20-63mm

Item No:W37772

 

1. Core functions and working principles

1. Hot melt connection operation

Main function: Connect pipes and fittings through hot melt to form a leak-free, high-strength pipeline system. For example:

Connect PPR water pipes during home decoration to realize the laying of hot and cold water pipes;

Weld PE-RT pipes in the floor heating project to build a floor heating coil network.

 

Connection advantages: Compared with threaded connection or glue bonding, the interface strength of the hot melt connection is equivalent to that of the pipe body, has good sealing performance, and is suitable for long-term pressure bearing (such as tap water pipes).

 

2. working principle

The fusion welder is heated to the set temperature (usually around 260℃) by the built-in heating element (heating plate), and the pipes and fittings are inserted into both ends of the heating plate respectively (the pipes are inserted into the heating column, and the pipes are sleeved into the heating sleeve), and the contact surfaces are melted and formed. After turning, quickly pull out and insert into each other, and cool down, complete the connection.

 

 

2. Adaptation scenarios for 20-63mm specifications

1. Building water supply and drainage engineering

Indoor pipes: 20mm (4 points) and 25mm (6 points) specifications are used for domestic tap water pipes (such as kitchen and toilet water pipes);32mm and above are used for main pipes or large-flow water supply for villas.

 

Drainage pipes: Some PE drainage pipes are connected by hot melt, and the 63mm size can be used for balcony floor drains and kitchen drainage branch pipes.

 

2. Floor heating and heating and ventilation systems

Floor heating coils: 20mm and 25mm PE-RT or PEX pipes are commonly used to connect the water sink and the coil through a welder to ensure tightness in a high temperature (below 60℃) environment.

 

Heating pipes: Most indoor PPR heating pipes for central heating in the north use hot melt connections in 25mm and 32 mm.

 

3. Industrial and agricultural applications

Industrial pipelines: For the transportation of corrosive liquids (such as PPH pipes) in chemical workshops, the 63mm size can be used for medium-flow pipelines, and the fusion connection avoids the risk of leakage.

 

Agricultural irrigation: The main pipe connection of PE irrigation pipes (such as drip irrigation and sprinkler irrigation systems), with a 20-63mm specification to adapt to the flow needs of different plots.

 

4. Repair and renovation scenarios

Pipe repair: When the existing plastic pipe is damaged, use a welder to cut the damaged part and melt the new pipe to replace it;

Transformation of old pipes: When replacing galvanized steel pipes with PPR pipes, use a welder to connect the new pipes with water meters, valves and other accessories.

 

3. Advantages and limitations of the 20-63mm specification

Advantages:

Covering common specifications: 20-63mm is the most commonly used pipe diameter range in construction projects, and a set of fusion splitters can meet more than 90% of household and small engineering needs;

Balance between portability and efficiency: Compared with larger specifications (such as 110mm), the 20-63mm model is smaller in size and lighter in weight (about 1- 2 kg). It is suitable for home decoration electricians and has high heating efficiency (heating up to 260℃ for about 5 minutes).

 

Restrictions:

Unable to connect pipes with diameters less than 20mm or more than 63mm (special model required);

The operating technical requirements are high, and improper control of temperature and welding time may easily lead to water leakage at the interface (such as insufficient heating and not melting, or excessive heating of the material is carbonized).

 

 

4. Usage process and precautions

1. standard operating procedure

Pretreatment: Use a cutter to cut the pipe vertically to remove burrs; clean the pipe and pipe fittings interface to ensure that there is no oil or dust.

 

Heating preparation: Power on the welder and heat it to the set temperature (PPR is usually 260℃), insert the pipe into the heating column, and put the pipe into the heating sleeve. The insertion depth must reach the scale line (for example, the insertion depth of a 20mm pipe is about 18mm).

 

Melting and connection: Hold for 10-15 seconds (adjust according to specifications, such as 20mm for about 10 seconds, 63mm for about 15 seconds), after the interface appears uniform flanging, quickly pull out and insert it into each other, and hold it still for 10-30 seconds until it cools.

 

2. key considerations

Temperature control: Different materials have different melting points (such as 230℃ for PE and 260℃ for PPR). It is strictly prohibited to cause material decomposition due to excessive temperature use.

 

Operation accuracy: Keep the pipe and pipe fittings vertical during insertion to avoid tilting and causing eccentricity of the interface (eccentricity>0.5mm is prone to water leakage).

 

Safety protection: The temperature of the heating plate is extremely high, so you need to wear insulating gloves when operating to avoid touching it; cool it for 30 minutes after use before storing it to prevent burns.

 

Maintenance: Use a clean rag to wipe the plastic residue on the surface of the heating plate after each use to avoid carbon deposits affecting the quality of the next welding; for long-term storage, power off and place in a dry place.
