The innovation circular woven reinforced textile rehabilitation hose is invented by ENST, which is seamless and jointless knitting with circular woven machine, mix with preventing cover, reinforcement and sealed liner. It is designed based on the requirements on abrasion resistance cover, high-pressure reinforcing and sealed for environment friendly. From material to construction, it is suitable for pipelines with pressure, temperature, streams, etc., which is quite available for municipal pipelines, industrial waste liquid transferring, renewal of leaked pipelines, emergency and chemical liquid transferring. And with the sealed liner is potable, it’s absolutely safe and environment friendly.

1. Construction: Three-layer design, long service life

2. Advantages

（1） Higher pressure, maximum working pressure is 24 MPa/ 3,480 PSI and burst pressure 36 MPa/ 5,221 PSI with the hose only

（2） Available at different temperatures, from -40℃~120℃/ -40℉ - 248℉, no leaking at low temperature, no deformation at high temperature. No matter daily life, or industrial requirements.

（3） Durable character, bending resistance at 40,000 times, abrasion resistance at 0.5-1.2cm³/ 0.03- 0.07 inch3, adhesion is over 80N/25cm2/ 116 psi

（4） Single length: 5,000 meters / 3.11 miles at DN200 / 8 inches to reduce the number of couplings and the cost of approaching. It also greatly reduces the risks afterwards.

（5） Light in weight, 2.0 - 27.3 KG per meter / 1.34 – 18.34 LB per foot, flexible, available at 90° with R=5D bending. No particular equipment required, can be approached at narrow space.

（6） Long service life, theoretically over 50 years with aging resistance raw material. Much better on maintenance than original pipes.

（7） Safety and environment friendly: food-grade material, no harmful substances release, suitable for potable water or other specific environmental requirements.

1. Regular characters (Optional)

1. Characters with standards

According to different situation, we offer special products upon request

· Diameters: DN80-DN1400/ 3 1/4 – 55 inches, other diameter or wall thickness on request

· Pressure: according to different liquid and working/ burst pressure

· Construction: single or double reinforcement, or specific corrasion resistance cover and liner

· Length: different lengths, maximum at 5,000 meters/ 3.11 miles

ENST could definitely design, manufacture and install trenchless rehabilitation hoses for different situations with independent intellectual property rights and manufacturing ability. All the products can be strictly detected by third party.  All the characters are much better than industry standards. Technical innovation, quality first is the concept of ENST, we supply high efficient, safe and durable solutions to the liquid transferring, focusing on high-quality, high-efficiency, low-cost and low-consumption.
