Description of High Density Polyethylene (HDPE) fabricated segments fittings

Assembly fittings With its ability to accommodate non-traditional angles, fabricated fittings are often used in 12-inch and larger applications where molded fittings cannot be used. Being able to use specialized fusion cells for machining and manufacturing, its flexibility allows create exactly what customers need.

Segmented joints are the latest technology in large diameter polyethylene pressure piping systems. Max. injection molded fittings are available in 1200mm OD and moulded stub ends and end caps are available in 1600mm OD. Segmented joint is the first choice at larger diameters fitting. High-quality pipe and proper welding method are most important to ensure the required stability,uniformity, and strength.

It is important to know that PE100 fittings which made from PE100 pipes will have reduced pressure ratings. The maximum allowable working pressure will be derated once the fabricated fittings are attached to the pipe, and different PE fitting geometries has different derating factors.

For tees made from pipe sections, the following derating rules for calculating PN shall apply:

PN = fT×PNpipe

where fT is the derating factor for these tees with a value of 0.5;

PNpipe is the nominal pressure of the pipe.

For elbows made from pipe sections, the following derating rules for calculating PN shall apply:

PN = fB×PNpipe

where Fb is the derating factor related to the design of the bending section as follows;

HDPE Fabricated Segments Fittings

Characteristics And Advantages of High Density Polyethylene (HDPE) socket fusion fittings：

• 1. No leakage: The connection is reliable, and the strength of the butt fusion interface between the pipe fitting and the pipe is as good as the pipe itself, and has the same life expectancy.
• 2. Non-toxic: do not scale, do not breed bacteria or contain heavy metal additives.
• 3. Wear resistance: It has excellent wear resistance. Since its inner wall is lubricated and the friction coefficient is extremely low.
• 4. Corrosion resistance: PE pipe fittings are made of inert materials. They has good corrosion resistance to galvanic corrosion such as electrical current, salts in the soil, acids and water vapor. The pipe fittings can be used immediately without any anti-corrosion treatment.
• 5. Shock resistance: good flexibility, high impact strength, strong shock resistance, can be used in many applications.
• 6. Reduce project costs: The welding process at the interface is simple, the connection of pipe fittings is fast and convenient, and the total project cost is low.
• 7. Light weight: They are convenient to transport and install with long service life.
