Thetechnology of
LSAW steel pipe is simple, high production efficiency, low cost with fast development. And strength of
SSAW steel pipe is higher than LSAW steel pipe, we could produce large
dimeter welded pipes with narrow steel plate, also we could produce different outside diameter with the same width material. But compare with same length LSAW, the length of the welding line will
increase 30%~ 100%, and low produce speed.
Range of Application
Welded steel pipes is widely used in public waterworks, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction. It's one of 20 key products of our country's development. As for gas trasmission, coal gas, steam gas and liquefied petroleum gas. For structure, drill pipe, bridge; and for wharf, road, building structure and etc.
