W Series Drain Pipe Lining , Internal Pipe Lining For Water Main Pipe Rehabilitation

Pipe-in Liners are classified into four different series: Pipe-in Liner W Series, Pipe-in Liner O Series, Pipe-in Liner G series, and Pipe-in Liner H series.

►Pipe-in Liner W series are used to rehabilitate pressure pipelines, including water main pipes and force mains at normal temperature.

►Pipe-in Liner O series are used to rehabilitate oil pipes both onshore and offshore.

►Pipe-in Liner G series are used to rehabilitate gas pipes both onshore and offshore.

►Pipe-in liner H series are used to rehabilitate pipes in municipal heat system. Pipe-in liner H series can resist a temperature up to 95° C (203° F).

Furthermore, Asoe is the first company in the world to develop this type of solution to rehabilitate hot water pipes.

Besides liners, Asoe also supplies complete solutions and accessory equipment, including couplings to connect Pipe-in Liner with host pipes, equipment to install couplings, and technical consulting etc.

Pipe-in Liner solution is a semi-structurally independent rehabilitation technology. There is no connection between the host pipe and the liner; the liner works independently from the host pipe. The liner is rigid and maintains the round shape inside the host pipes when there is a vacuum inside the host pipe or when there is temporary external pressure on the host pipe.

ASTM installation guide and design guide are available upon request.

Connectors (PILC Couplings, Patent Protected)

•Choose section of host pipes to be rehabilitated

•Install by-pass hoses in order to keep transferring flow during

rehabilitating

•Dig construction pits at two ends

•Inspect pipes with a mobile TV camera and analysis of video recordings

•Mechanical coarse cleaning of host pipes with scraper pigs

•Clean host pipes by water jetting

•Position Pipe-in Liners at the start pit and the pulling winch at

destination pit

•Install pulling head onto liner

•Install hose guides

•Fold Pipe-in Liner into U-shape and bind the liner with scotch tape

•Pull liner into the host pipes

•Install PILC couplings onto the host pipes

•Hydrostatic pressure test or air pressure test

•Install transition pipes

•Recover transferring fluid

•Remove by-pass and close pit

Asoe manufactures differnt hoses, including through-the-weave PU layflat hoses, through-the-weave NBR layflat hoses and jacketed fire hoses etc. Jacketed fire hoses are lined with EPDM, Polyurethane (PU), Nitrile rubber (NBR), PVC, Natural rubber (NR) and CR etc. Asoe fire hoses can meet or exceed the technical standard requirement of NFPA 1961, UL19, FM2111, EN14540, EN14811, DIN and BS6391 etc. Some PU covered layflat hoses meet NSF61 standard, which are appropriate for transfering potable water.

Asoe designs and manufactures hose couplings which works with Asoe hoses. According to different technical requirement in different applications, Asoe team design appropriate couplings. The materials applied in couplings are aluminum, carbon steel, stainless steel 304, SS316, SS316L, PA6 reinforced Nylon, PE, and PP etc. The couplings includes LDHC series of couplings, HPHC FM couplings, Storz couplings, camlocks, instantaneous forestry couplings, bauer couplings, etc.

Asoe offer some equipments which are used to handle hoses, assembly hoses, installing hose projects etc.

Asoe team would like to work with its customers to design new customized solutions which no other layflat hoses manufacturer can supply. Asoe team have enthusiasm in challenging new hose solutions and have expertise in hoses manufacturing, designing, and application, which ensure that Asoe can be a strong back for its customers.

Asoe continously created a lot of new hoses solutions in different industries. These webpages can't details all of them. You are welcome to contact Asoe's sales team.
