Sleeve pipe, plays a part of the knee protection to stainless steel elbow body, can avoid the extrusion and collision damage of transportation knee
The not both economical loss caused, and the ingenious surface for having covered up knee wrinkle, by being applied on the external wall of stainless steel elbow
Some skin of paints so that the outward appearance of bend pipe is more attractive in appearance, meanwhile, it is capable to prevent bend pipe to be chronically exposed to corrosion in air and damage,
By the titanium alloy anti-corrosion layer being provided with stainless steel elbow body on wall, the decay resistance of bend pipe is improved, it is to avoid curved
After pipe is used for a long time, by working fluid corrosion and damage inside it, service life is long, by corrosion-resistant in skin of paint and titanium alloy
The carbon felt heat-insulation layer and carbon steel layer being provided between layer, carbon felt heat-insulation layer improve the heat-insulating property of bend pipe, it is to avoid bend pipe bursting by freezing
Damage, carbon steel layer improves the hardness and tensile strength of bend pipe, can adapt in various rugged environments, practical, lead to
Cross the sealing ring being provided with the wall of nipple side, when two identical bend pipes are combined, can ensure two it is curved
Sealing property between pipe, it is to avoid working fluid flows through excessive during two identical bend pipe junctions.
Compared with prior art, the beneficial effects of the utility model are:The utility model exists.
