304 pipe no blisters, no sand hole, no spots, no cracks, flat bead. Bending, cutting, welding performance advantages, nickel content is stable, the product conforms to China GB, the United States ASTM, Japan JIS and other specifications!
Product details editor
304 stainless steel welded pipe is resistant to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosive medium corrosion of steel pipe. Also called stainless acid resistant steel pipe.
304 the corrosion resistance of the welded pipe depends on the alloy elements contained in the steel. Chrome is made of stainless steel corrosion resistance for the basic elements, when the Cr content in steel reaches about 12%, the oxygen effect of chromium and corrosive medium, to form a thin film on the surface of steel (self passivation film), the matrix can prevent further corrosion of steel. In addition to chromium, the alloy elements commonly used in stainless steel welded tubes are nickel, molybdenum, titanium, niobium, copper, nitrogen and so on, so as to meet the requirements of various uses on the structure and properties of stainless steel.
304 welded pipe is a hollow strip of round steel, widely used in petroleum, chemical, medical, food, light industry, machinery, instruments and other industrial transmission pipelines and mechanical structural components. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Feature editor
304 the thicker the wall of the welded pipe is, the more economical and practical it is. The thinner the wall thickness is, the higher the processing cost will be;
Process of 304 pipe limits the performance of it, generally low precision welded steel pipe: uneven thickness, high brightness, light pipe inner surface length high cost, and the internal and external surface pitting and black spots difficult to remove;
304 the inspection and shaping of the welded pipe must be done off-line. Therefore, it reflects its superiority in high pressure, high strength, mechanical structure and timber
