Large diameter steel pipe demand

Along with the rapid development of our industrial modernization of national economy, the rapid progress in various industries, metallurgical production in the supply and demand of total steel has surged. Especially in recent years, the average growth in manufacturing in steel tube stayed above 20%,which not only makes our country of pipes, the international social than one of the main indexes degree ascent to 7%, steel pipe production grown to be the world's first. And system tube technical equipment advanced technique level, product quality index levels, there has been a significant improvement. Our country has entered the world steel tube power list. Which although more than 400 mm in diameter of large diameter pipe production has lag behind demand, but also got great ascension.
In 2000,the stretching 4000 miles of pipe 1.6 million tons, consumption "west-east gas transmission" project started, not only pulled open our oil and gas long-distance pipeline construction is prelusive, also broke the silence of large diameter pipe production in twenty or thirty years of low-speed wandering situation.
Adapt to oil and gas transportation, oil exploration, construction steel structure industry needs, a batch of represents contemporary international level swig straight seam submerged arc welding tube (UOE. JCOE) production line. Straight seam hf hanguan (ERW) production line, double-sided submerged arc spiral welded pipe production line SSAW) (one for materials. Adapt to power stations, boiler tube, large diameter of oil-well tubing market demand, batch of introducing or have our independent intellectual property cone shaped roll two large diameter new roll pipe bender, three rollers PQF mill, large pipe jacking units, disc rotating hole diameter of large diameter unit seamless tube lines has put into production or preparation. Although the west-east gas transmission project high quality big straight seam welded pipe we more rely on imports, although so far we still have about 0.15 million tons annual large diameter high-medium pressure boiler tube station tube, special, pipe etc seamless steel tube Wells need to bring in. But on the whole, our country has gone into operation and plan future big caliber welded pipe and seamless tube production capacity has a meet, adapt, and even some varieties have excess demand of economical development peaked the basic framework.

Hei Yan Group is engaged in pipe and fitting machinery,and be responsible for the large diameter steel pipe line production.
