LAY-FLAT HOSE FOR OILFIELD HYDRAULIC FRACTURING OPERATIONS

摘要

A lay-flat hose is manufactured by single-extrusion of rubber through a cylindrical polyester weave jacket to limit swelling and expansion upon pressurization. Forcing the rubber compound through the weave creates a single homogenous construction without the use of glues or adhesives. The lay-flat hose is lightweight and durable.

主权项

1. A lay-flat hose for use in pumping liquids, comprising:
the hose formed from a nitrile rubber compound and a polyester weave placed between an interior surface and an exterior surface of the nitrile rubber compound, the hose being to lay-flat hose such that the hose collapses to a substantially flat configuration when pressurized fluid is not transmitted through the hose and the hose expands to a substantially circular cross-sectional configuration when pressurized fluid is transmitted through the hose.
