LSAW steel pipe features let it invincible position

LSAW steel pipe features: Longitudinal production process is simple. Low interest rates, rapid development. Plastic, spiral and standard classification: pressurized fluid transport spiral submerged arc welded pipe (SY5036-83 is mainly used for transporting oil, natural gas pipelines; pressure fluid transmission high-frequency welded spiral seam steel pipe (SY5038-83 lap welding method with high-frequency welding of the pressure fluid delivery for high-frequency welded spiral seam steel pipe steel tube strong pressure. to facilitate the welding and machining molding; generally low pressure liquid delivery spiral submerged arc welded pipe (SY5037-83 single-sided double-sided automatic submerged arc welding or welding into the legal system for water, gas, air and steam is generally low pressure liquid delivery such as submerged arc welding steel pipes In 2009, China’s response to financial crisis, from time to time introduced the policy of economic comfort, steel users and traders of steel is expected to rebound in the market higher. all aspects of the survey show that the current inventory straight seam steel pipe not only restore the 2008 level, and on this basis, a further rise, “In 2009, the whole society of steel, Billet Straight seam steel pipe inventory increase equivalent to 30 million tons at present, social steel billet of high inventories, stabilize the steel market has been a threat to the Government issuing the credit limit the size of the steel industry, the credit crunch on the large steel straight seam steel pipe manufacturer impact limited little effect on steel prices.

Spiral welded pipe(SSAW) strength is generally higher than the Longitudinal, can narrow the larger diameter pipe billet production, you can also use the same width of the billet production of different pipe diameters. But with the same length of straight seam pipe compared to the weld length of 30 to 100 percent of the production rate is low. Therefore, the smaller diameter pipe actually use straight seam welded, large diameter spiral welded pipe is mostly used. Bank has increased the intensity of the mortgage, since the second half of 2008 since the financial crisis. And steel companies to give preferential interest rates, many steel projects of its own funds rate has decreased, but the steel industry faces overcapacity and eliminate backward and other problems, naturally become one of the main targets of the credit crunch, however, iron and steel enterprises, especially large steel companies are not short of money “often warm extrusion, straight seam steel pipe production technology: The strip coil as a raw material for automatic double-sided submerged arc welding process wire spiral seam welded steel pipe production efficiency is high.
