Irrigation & Plumbing Polyethylene Pipe Fittings

Introduction of Polyethylene Pipe Fittings

Polyethylene Pipe Fittings (High Density Polyethylene pipe fittings) is a pipe connection component made of high density polyethylene (high Density Polyethylene) as the core material, designed for matching HDPE pipe system. As a revolutionary product in the field of modern fluid transportation, it has become an ideal choice to replace traditional metal pipe fittings and PVC pipe fittings with its excellent corrosion resistance, impact resistance and long service life.

Cov ntsiab lus ntawm Polyethylene Pipe Fittings

Type of Polyethylene Pipe Fittings: elbow (45°/90°), tee, reducing joint, flange joint, HDPE end cap, etc.

Diameter Range: DN20-DN1200 (support non-standard customization)

Pressure Rating: PN6-PN25 (0.6-2.5MPa)

Technical Parameters

1. Environmental protection and non-toxic: in line with food grade material standards, suitable for drinking water transportation.

2. Strong corrosion resistance: resistant to acid and alkali, salt spray and chemical media erosion, no risk of rust.

3. Flexible seismic resistance: high elastic modulus can resist foundation settlement and earthquake impact.

4. Lightweight design: the weight is only 1/8 of the metal pipe fittings, and the transportation and installation cost is reduced by more than 50%.

5. Life of up to 50 years: maintain stable performance in -60°C to 60°C environment.

FAQ of Polyethylene Pipe Fittings

Q1: Can Polyethylene Pipe Fittings be directly exposed to sunlight?

A: Standard products need to add anti-UV agent, outdoor service life can reach more than 20 years. It is recommended to use black pipe fittings (carbon black content ≥2%) in long-term sunshine environment.

Q2: How to judge the welding quality of electric fusion pipe fittings?

A: It can be verified by three points:

• observation hole flanging height ≥1mm
• no shrinkage phenomenon after cooling
• Use the data recording function of the electric fusion welding machine to verify the welding parameters.

Q3: How to connect Polyethylene Pipe Fittings and steel pipes?

A: It is recommended to use flanged transition joints. It should be noted that:

• The end of the steel pipe should be treated with anti-corrosion;
• The EPDM sealing gasket should be used;
• The bolt torque should be controlled at 30-40N·m.

Q4: How long can Polyethylene Pipe Fittings be stored in stock?

A: The shelf life of unopened original package is 5 years in a dry and dark environment. It is recommended that unopened products be used within 12 months.

Q5: Can different brands of Polyethylene Pipe Fittings be mixed?

A: Mixing is not recommended. Due to the difference in the melting index of raw materials may lead to the delamination of the welding interface, if it is necessary to mix, it is necessary to verify the welding process in advance.
