What kinds of PVC hoses are there?

It is mainly divided into thread hose, drain hose, ventilation hose, shower hose and harness tube.
According to the material, it can be divided into stainless steel hose, metal hose, corrugated hose, rubber hose and plastic hose. A metal hose is mainly a spiral corrugated pipe, and the other is a corrugated bellows. Helical bellows are spiral shell with corrugated arrangement. There is a spiral elevation angle between two adjacent bellows. All the bellows can be connected by a spiral line.
Ring bellows are closed circular shell with corrugated rings, and the waves are connected in series by ring bellows. Annular bellows are formed from seamless pipes or welded pipes. Constrained by the processing method, the length of the single tube is usually shorter than that of the spiral corrugated pipe. The advantages of annular bellows are good elasticity and small rigidity. Double hook hose, >120 Kg, strong torque, ensure no crack, no leakage.
Comprehensive test: special PVC inner tube or EPDM inner pipe is tested by water pressure 400PSI and 80 degrees.
Nut style: nuts are of various styles. Nut material: copper or stainless steel.
Connector style: advanced connector design, fixed type and 360 degree rotary type. Joint material: copper or stainless steel.
Hose structure: solid structure, through compression, tensile and torsion testing.
