The development of thermal contraction steel pipe production technology

Date:2023-01-23View:234Tags:seamless pipe manufacturers,api 5l pipe,lsaw pipe

Heat-shrinkable diameter steel pipe production technology development began in the early nineteenth century oil development in the rise of the bicycle manufacturing industry, during the two world wars, ships, boilers, aircraft manufacturing after World War II thermal power boiler manufacturing, chemical industry development and oil and gas drilling and transportation, a strong impetus to the development of the steel industry in the varieties, yield and quality.

Precise heat shrinkable diameter steel pipe produced by the hot-rolled steel, cold rolling or cold drawing process to produce hot-rolled perforated small size of the precision steel tubes outside the hot-rolled, there are precision steel pipe steel pipe in the proportion of recent years, stable at 42 % to about 45% of the pipe upward trend. precision steel tubes and welded steel tube compare materials reliability and adaptability of varieties especially adapted to the production of thick-walled and alloy steel. Main problem is the high investment, high cost and complex manufacturing process, the wall thickness and tolerances and welded pipe is actually plate deep processed products, the price of similar conditions, precision steel market competitiveness of the pipe network because of its reliability and improved plate quality of continuous improvement and raise the level of pipe technology and equipment, the market occupied by the part of the seamless pipe, welded pipe alternative possibility, but only very limited number of areas.
