Steel lining plastic straight pipe
一、Product overview
Steel liner PO pipe fittings products, seamless steel pipe, the shell adopts fluid liner PO (polyolefin) materials. Polyolefin (PO) in polyethylene, polypropylene, butene, such as the floorboard of the olefin polymers, is one of the most ideal anticorrosion material at present. Our company produces the steel liner PO tube, adopts the seamless steel tube as the matrix, over-current part adopts the thermoplastic material (PO) in thermoplastic rotating centrifugal roller frame a molding process. Because gangsu adhesion is very strong, so it has both the strength of the metal, and PO corrosion resistance, resistance to high temperature and low temperature, negative pressure, anti-aging properties. Lining equipment such as tank, tank, reaction kettle, the lining of the PO can be used as a secondary repair.
Nominal menstruation of 500 ㎜ or larger diameter steel lining plastic straight pipe and pipe fittings, 1.5 2.5 ㎜ on the inner wall of the steel spot welding of metal wire mesh, in order to increase the thickness of the lining plastic parts and the price is high adhesion, not easy to fall off and cracking.
