PP Flange

Product Description

PP Flange is a pipe connection method. It is completed by fixing two pipes, pipe fittings or equipment on a flange plate, then adding a flange gasket between the two flange plates and fastening them together with bolts.

This connection method belongs to a type of flange connection, where PP stands for polypropylene, which is a commonly used plastic material.

PP fiber backing ring

A new PP reinforced, full plastic backing ring flange, It’s a new corrosion-free,full plastic,fiber reinforced PP light weight, reliable, and with long life span. Size will go up to 400mm.

It is not only for HDPE piping system,but also for PPH,PPR ABS UPVC etc.

Structure

PP Flange connection or flange joint is a combined sealing structure composed of flanges, gaskets and bolts connected to each other, which can achieve detachable connection. This connection method is widely used in construction, water supply and drainage, heating, air conditioning and other fields. Because of its excellent corrosion resistance, high temperature resistance, pressure resistance and good sealing performance, it can be used in various harsh environments, such as high temperature, high pressure, acid and alkali environments.

PP Flange connection advantages

1. Lightweight and durable: PP Flange is made of polypropylene, a polymer formed by propylene addition polymerization, which is light and durable. Its density is 0.89～0.91g/cm³, its melting point is 165℃, and it has good performance in the temperature range of -30～140℃. PP Flange is not only light in overall weight, easy to install and maintain, but also has high durability. ‌

2. Flexibility and shock resistance: It has good flexibility and can effectively absorb pipeline vibration, reduce noise and impact, and thus provide better shock absorption effect. ‌

3. Reliable sealing: It adopts advanced sealing technology to ensure that the joint still maintains excellent sealing performance in harsh environments, avoiding leakage problems caused by poor sealing. ‌

4. Easy to install and maintain: Compared with metal flanges, plastic flanges have the advantages of light weight, easy installation, and low maintenance cost, so they are widely used in various industries.‌
