How to weld high-pressure tubing to avoid oil leakage?

Do not repair welding, drain oil and take fire prevention measures before construction.

Welding or gas welding can be used for repair. Use covered electrode matching the pipe. Gas welding can be repaired with brass welding wire.

3.2 welding electrode. The current of 1 10 ~ 150 depends on different welding positions. Because of unskilled operation and too small welding gun, the welding is uneven, easy to be virtual welding and incomplete welding.

Large pipelines in open space can also be solved by hoop without repair welding.

The tubing consists of steel wire wound skeleton layer and internal and external oil-resistant and corrosion-resistant synthetic rubber. Hydraulic oil pipes used to transport construction machinery, submarine natural gas, petroleum, irrigation, steel mills, chemical plants and other media.

Classification: high-pressure steel wire braided hose, high-pressure steel wire wound hose, large-diameter high-pressure hose, steel wire (fiber) reinforced nylon elastomer resin pipe, steel wire reinforced soft ultra-high pressure hose, high-temperature resistant hose and polyurethane hose.

Structure: High-pressure tubing consists of steel wire wound skeleton layer, internal and external oil-resistant rubber, corrosion-resistant synthetic rubber and weather-resistant special rubber.

Uses: Used in excavators, loaders, dumpers, hydraulic power, hydraulic supports, cement pipes, agricultural irrigation hoses, hydraulic pipes of construction machinery, submarine natural gas transportation and oil transportation.
