Flexible multiple high pressure conveying hoses, non-adhesive, no corrosion
Structures of flexible multiple high pressure conveying hoses
The flexible multiple high pressure conveying hose is made of polymer composites. It is a kind of pipes used for petroleum and gas industry. It has the following features: high strength, high pressure, corrosion resistance, scaling resistance, low coefficient of friction resistance, good heat preservation, good flexibility and long service life. The flexible multiple high pressure conveying hose consists of polyethylene resin inner core tube, stainless steel core tube, reinforcement layer and external protection layer.
The flexible multiple high pressure conveying hose may divide into oil conveying multiple hose, gas conveying hose, water conveying hose and methanol injection multiple hose according to its use. All kinds of hoses have different diameter, usage, nominal pressure and schedule.
The materials used for making the flexible multiple high pressure conveying hose include stainless steel pipe, polyethylene resin, reinforcement fiber and wireline.
