MECHANICAL COUPLINGS FOR JOINING POLYETHYLENE PIPE 1.0 Introduction The use of polyethylene piping material has steadily increased over the past half century and today it’s the material of choice for natural gas piping systems up to 12” size.

Mechanical Joint Fittings One of the most common connections from DI pipe to other pipe is with the use of Mechanical Joint Fittings (MJ). Since DI pipe is manufactured to an industry standard “Outside Diameter” (OD), no matter the manufacturer, all DI pipe will have the same OD in each size. Puhui Pipe manufacturer in China

PE & HDPE Pipe PE100 is the third generation of pipe grade PE. It has an optimum balance of three key properties: Minimum Required Strength (MRS) – this provides long-term strength and creep resistance. Stress crack resistance (sometimes referred to as slow crack growth resistance). Puhui Pipe manufacturer in China

The use of tough PE100 polymer ensures that Excel pipe is highly resistant to fast fracture even in the most hostile conditions. This allows Excel to operate at higher working pressures than PE80. Enhanced Material Requirements of the PE100+ Association

16/9/· Plastic Pipe Institute (PPI) and many pipe manufacturers publish the minimum bend radius recommended for HDPE pipe. These values vary by pipe diameter, wall thickness and material. Pipe tested with Victaulic ® couplings meet or exceed the pipe recommendations, meaning the joints maintain their integrity at tighter radii of curvature than recommended for the pipe itself.

HDPE pipes made form grade PE100 material can be welded by this method for pipes with a diameter of 20mm up to 1000mm. Butt – Welding This is the most common method used when it comes to joining HDPE pipes and fittings.

560mm x 12m PN16 PE100 HDPE pipe SFOE T1000/3 (SDR11) - FR (flame-retardant) Coated - this system is safe for underground mining. Office Contact +27(012) 376 2347

B&C Reverse Thread Couplings, aka Jackmoon Couplings are non-metallic high-pressure rated airtight couplings for HDPE pipe and conduit. Right and left hand Jackmoon fittings couple innerduct during pulling and directional drilling operations.

Chapter 15 General Guidelines for Repairing Buried PE Potable Water Pressure Pipes 517 test all tie-in joints and the squeeze-off areas at system pressure after the repair is complete. If recommended by the manufacturer, any anti-static fluid should be rinsed from Puhui Pipe manufacturer in China

Features of HDPE pipes and fittings: Green environmental protection: HDPE pipe non-toxic, tasteless, after strict health monitoring, belongs to green building materials, never scale, can effectively improve water quality. Corrosion resistance: HDPE pipelines are resistant to corrosion by a variety of chemical media, and chemicals present in the soil do not cause any degradation to the pipeline.
