Plastic Pipe Clamps | Hydraulic Tube Clamps | PP / PA tube clamps

Plastic pipe clamps usually refers to a group series of pipe clamps made of material plastic, including nylon. The most popular types of plastic pipe clamps are hydraulic plastic pipe clamps. These types of plastic pipe clamps are widely used in various industries especially in hydraulic industries.

Younglee Metal Products Co., Ltd is one of the top quality plastic pipe clamp suppliers and manufacturers in China. Our factory has rich experiences and knowledge in plastic pipe clamps designing, manufacturing and quality controlling.

Specifications of Plastic pipe clamps

Plastic pipe clamps are designed according to many different specifications, and for hydraulic plastic pipe clamps, the specifications are German standard DIN 3015-1, DIN 3015-2 and DIN 3015-3.

And some times plastic pipe clamps are designed according to the users’ request and drawings. However, a number of company’s has their own specifications of hydraulic plastic pipe clamps, and their specification actually is equal to or similar to DIN 3015.

Materials of Plastic pipe clamps

Polypropylene:
Polypropylene pipe clamps are with working temperature -30 to 90 Celsius degrees, they known as PP pipe clamps also.
PP pipe clamps
Polyamide pipe clamps:
Polyamide pipe clamps are with working temperature -30 to 120 Celsius degrees, they known as PA pipe clamps or Nylon pipe clamps also. Polyamide pipe clamps are usually for high temperature applications or sometimes for UV resistance applications.
PA pipe clamp
Rubber pipe clamps
Rubber pipe clamps are usually used for anti vibration purpose, they are used in hydraulic lines or fluid systems where higher vibration and shocks exists. Or used as hydraulic hose clamps.

Main series & Size Range of Plastic pipe clamps

Plastic pipe clamps are designed for full range of hydraulic tubing sizes and wide range of tubes of other applications.

As the top quality China pipe clamp manufacturer & suppliers, Younglee produces and supplies plastic tube clamps in series and sizes as below.

Light series plastic tube clamps

This series of plastic pipe clamps are designed for fastening and installing tubes under light or normal mechanical pressure, or the system vibration is light. Light duty plastic tube clamps are designed for tubes, pipes and cables with outside diameter from 6 mm to 102 mm.

For tubes with O.D bigger than 102 mm, we will need to use heavy duty pipe clamps.

Heavy duty plastic tube clamps

This series of plastic pipe clamps are designed for fastening and installing tubes under heavy mechanical pressure, or the system vibration is heavy. Heavy duty plastic tube clamps are designed for tubes, pipes and cables with outside diameter from 6 mm to 508 mm.

Twin series plastic tube clamps

Twin plastic pipe clamps are known as double plastic tube clamps also, they are designed for fastening and installing two tubes or rods, cables in parallel.

The size range of with outside diameter from 6 mm to 43 mm.

There are two series of plastic twin tube clamps which are light duty twin tube clamps and heavy series twin tube clamps.

Advantages of plastic tube clamps

Plastic pipe clamps are popular in industries for the below advantages.

Anti vibration

With plastic tube clamps, the noise and vibrations of the tube system can be greatly reduced, which will great reduce the risk of leakage of the hydraulic tube systems.

Good corrosion resistant performance
Durable in use
