Price of stainNational standard thickness of stainless steel pipe when American standard stainless steel pipe is used, there are different tolerances for seamless hot expanded pipe, seamless cold rolled pipe and welded pipe according to different dimensions. For example, for hot expanded pipe with diameter less than 100mm, when the thickness is 4mm and less, the upper limit tolerance of thickness is 40%; If the standard of stainless steel pipe is Chinese standard, according to the tolerance of stainless steel pipe for fluid transportation in gbt14976, the tolerance here is the tolerance when ordering according to the nominal thickness; According to the manufacturing method, the thickness standard of stainless steel pipe is divided into hot rolling and cold rolling, including thin plate with thickness of 0.5-4mm and thick plate with thickness of 5-35mm. The specific gravity of stainless steel pipe is 9. The weight = specific gravity of length and width of thickness, and the weight of plate with thickness of stainless steel pipe of 1mm = 11 m 2 m 93 = 86 kg 2 m (length) 1 m (width) 0.01 M (thickness) 93 (specific gravity) = 0.1586 tons (weight)
In order to obtain seamless pipes with smaller size and better quality, cold rolling, cold drawing or a combination of both must be used. Cold rolling is usually carried out on a two high mill. The steel pipe is rolled in an annular pass composed of variable section circular groove and fixed conical plug. Cold drawing is usually carried out on a single chain or double chain cold drawing machine of 0.5 ~ 100t.
.All steel with openings at both ends and hollow sections, and with a large ratio of length to section perimeter, can be called steel pipe. When the ratio of length to section perimeter is small, it can be called pipe section or tubular fittings, which belong to the category of pipe products.

7. Distinguish between 316L and 304L. There are two kinds of commonly used stainless steel 30316l (or corresponding to the German / European standard 430844036l, the main difference in chemical composition between 316L and 304 is that 316L contains Mo, and it is generally recognized that 316 has better corrosion resistance than 304 in high temperature environment. Therefore, engineers generally choose 316L parts in high temperature environment. However, there is no absolute thing. In concentrated environment, 316L should not be used at any higher temperature! No However, this is a big problem. People who study mechanics have all studied threads. Remember a black solid agent that needs to be applied to prevent threads from biting under high temperature: molybdenum disulfide (MOS), from which two conclusions are drawn: No: [1] Mo is indeed a high resistance material (know what crucible gold is melted in? Molybdenum crucible!). [2] : molybdenum can easily react with high valence sulfur ions to form sulfide. Therefore, no stainless steel is super corrosion resistant. In the final analysis, stainless steel is a steel with more impurities (but these impurities are more corrosion resistant than steel). If it is steel, it can react with other substances.
Difference between L stainless steel pipe and stainless steel pipe: and L stainless steel are molybdenum containing stainless steel. The molybdenum content of L stainless steel is slightly higher than that of stainless steel. Due to the molybdenum in the steel,201 stainless steel welded pipe, the overall performance of this steel is better than that of and stainless steel. Stainless steel has a wide range of applications under high temperature conditions when the concentration of is lower than 15% and higher than 85%. In addition, stainless steel also has good chloride corrosion performance, so it is usually used in marine environment. The large carbon content of L stainless steel is 0.0, which can be used in applications where annealing cannot be carried out after welding and great corrosion resistance is required.
