Application of stainless steel welded pipe in different industries

An important aspect of the stainless steel plate, stainless steel pipe with deep processing and application, is the main material of petrochemical, pharmaceutical and food industry, is also the main components of power equipment, shipbuilding industry, refrigeration equipment, desalination equipment, so the stainless steel pipe application is very extensive.

The main features of the production of stainless steel welded pipes are light production equipment, low investment, quick effect, simple welding method, wide range of product specifications, high dimensional accuracy, small wall thickness deviation, smooth surface and high yield of finished products. In the case of mass production, the cost of stainless steel pipe is over 20% lower than that of seamless steel tube.

Now, with the rapid development of China’s domestic economic construction, the consumption of stainless steel continues to increase, and the demand for stainless steel pipes is very large, and the market prospect is good. stainless steel seamless pipe demand concentrated in the basic industries, such as petroleum, chemical, power generation, the demand for 2/3 of the total consumption of stainless steel seamless pipe, as well as automobile, shipbuilding, construction and environmental protection industry demand is relatively large. Stainless steel welded pipe is more used in the urban landscape, architectural decoration industry, the annual consumption of about 700 thousand tons. Industrial stainless steel welded pipe processing requirements are higher.

Made from stainless steel tube, from austenitic steel to martensite and ferrite steel, dual phase steel, high alloy steel, seamless steel pipe products, including cold, cold and hot extrusion tube tube tube, pipe, tube spinning centrifugal casting; welding tube includes plasma welding, argon arc welding, submerged arc welding the speed of light, welding and welding pipe, basically covering the standard specifications of all countries in the world can produce stainless steel tube, stainless steel tube specifications and varieties also reached more than 100 kinds of products, involving the use of industrial and civil fields. But overall, the domestic stainless steel pipe in the variety, specifications, quantity, quality and so on, and the market demand has a certain gap.

In the stainless steel pipe products and quantity: the general use of ordinary stainless steel pipe production has been in line with the overall market demand balance. Seamless steel pipe production capacity greater than the market demand, overcapacity, but in low grades, standard decorative stainless steel welded pipe‘s market oversupply, high standard of industrial pipe, insufficient production capacity, especially for the high requirements of the pipe industry, such as power plant with high pressure stainless steel boiler tube is not what good domestic goods.

In the stainless steel tube product specifications: general purpose small diameter stainless steel pipe production capacity greater than the market demand; large diameter and high requirements of stainless steel pipe, market demand, the gap is large, a lot of special or to rely on imports.

In the variety of stainless steel pipe, a large number of foreign countries use 304L, 316L and other ultra-low carbon stainless steel. Domestic urea level, high precision stainless steel, but the quality of the stainless steel tube is no guarantee; some special stainless steel technical difficulty, high quality requirements, such as power station boiler heat exchanger tube, pipe, urea fertilizer plant oil well pipe, still mainly rely on imports; in addition some corrosion of duplex stainless steel excellent resistance to domestic production, there are very few, still can not meet the market demand.
