PTFE Tube Reliable Connection

PTFE Tube reliable connection

A good pipe, not only should have a good economy, and should have a stable and reliable interface, material impact resistance, anti-cracking, anti-aging, corrosion and a series of advantages, compared with traditional pipe, HDPE pipe system with the following one Series Advantages:

⑴ reliable connection: polyethylene pipe system between the use of electric hot melt connection, the joint strength is higher than the pipe body strength.

⑵ low temperature impact resistance: polyethylene low temperature embrittlement temperature is very low, in the -60-60 ℃ temperature range of safe use. Winter construction, due to good impact resistance of the material, no pipe embrittlement.

⑶ good resistance to stress cracking: HDPE has a low gap sensitivity, high shear strength and excellent scratch resistance, resistance to environmental stress cracking performance is also very prominent.

⑷ good chemical resistance: HDPE pipe can withstand a variety of chemical media corrosion, the soil exists in the chemical substances will not cause any degradation of the pipeline. Polyethylene is an electrical insulator and therefore does not degrade, rust or electrochemical corrosion; it does not promote algal, bacteria or fungi growth.

⑸ resistant to aging, long life: containing 2.5.5% of the uniform distribution of carbon black polyethylene pipe can be stored in outdoor open or use for 50 years, will not be damaged by UV radiation.

⑹ good wear resistance: HDPE pipe and steel pipe wear resistance comparison test shows that HDPE pipe wear resistance of steel pipe 4 times. In the field of mud transport, compared with the steel pipe, HDPE pipe has better wear resistance, which means that HDPE pipe has a longer life and better economy.

⑺ flexibility: HDPE pipe flexibility makes it easy to bend, the project can change the way through the pipeline to bypass the obstacles, in many cases, the flexibility of the pipe can reduce the amount of pipe and reduce the installation costs.

⑻ low flow resistance: HDPE pipe has a smooth inner surface, the Manning coefficient of 0.009. Smooth performance and non-sticking properties ensure that HDPE pipes have a higher transmission capacity than traditional tubing, while also reducing piping pressure loss and water consumption.

⑼ easy handling: HDPE pipe than concrete pipes, galvanized pipe and steel pipe lighter, it is easy to carry and install, lower manpower and equipment needs, means that the installation costs greatly reduced.

⑽ a variety of new construction methods: HDPE pipe with a variety of construction techniques, in addition to the traditional excavation can be used for construction, but also can use a variety of new trenchless technology such as pipe jacking, directional drilling, Cracks and other means of construction, which is not allowed to excavate some of the places, is the only choice, so HDPE pipeline applications more widely.

"Hidden project" is a very important issue, if the water pipe leakage and burst will bring irreparable consequences.

In the past, the pipes used for water supply were mainly cast iron pipes. Outside the main sand cast iron pipe, indoor use of galvanized cast iron pipe. But because of the use of a few years after the easy to produce a lot of rust, breeding bacteria, serious harm to human health. The state has been in June 1, 2000 from the out of sand casting pipe and cold galvanized cast iron pipe, and gradually limit the use of hot-dip cast iron pipe to promote the use of aluminum-plastic composite pipe, new plastic pipe

The state also provides a variety of pipe and accessories related to drinking water pipes, must have the health department of the documents, can be sold.
