When installing and welding the fixed port of stainless steel pipe, it is difficult to vent on the inner side, and some sides are easy to be blocked. In this case,Belmerbon0cr17ni7al stainless steel strip, water-soluble paper + blocking plate can be used for blocking. That is, the easy to vent and good side can be blocked with blocking plate, the difficult to vent and bad blocking plate side can be blocked with water-soluble paper, and the weld on the outer side can be blocked with adhesive tape (see Table ) .Measures to improve the welding quality of stainless steel pipe in order to ensure that the outer surface of stainless steel pipe is not damaged and purified, the maintenance of stainless steel pipe should be strengthened in each process of consumption, mainly including the following three aspects: the processing and consumption of stainless steel pipe should have a special consumption workshop (wood board is well used) ,Stainless welded disc (grade I) gb- stainless steel pipe (grade I)Vickers hardness stainless steel pipe Vickers hardness test is also an indentation test which can be used to determine the hardness of very thin metal materials and surface layers. It has the main advantages of Brinell and Rockwell methods and overcomes their basic disadvantages, but it is not as simple as Rockwell method. Vickers method is rarely used in steel pipe standards.Limassol,The intergranular corrosion of austenitic stainless steel can be prevented by adding Ti, Nb and other elements that can form stable carbides (tic or NBC) and avoiding the precipitation of crc on the grain boundary.Body austenitic stainless steel seamless steel pipe and welded steel pipe stainless steel pipe for mechanical structure stainless steel pipe for ordinary pipe stainless steel pipe for boiler, stainless steel pipe for heat exchanger and seamless steel pipe for chemical industry (crnit) qhyad crnimosi duplex stainless steel seamless steel pipe. Stainless steel is mainly used in the automobile industry, accounting for more than % of the total consumption of automobile stainless steel, and % is ferritic stainless steel. The exhaust gas produced by automobile engine is from the rear of intake pipe, front pipe, hose, converter and center pipe. The common steel grades of exhaust system are L, l,Belmerbon2Cr13 stainless steel strip, etc. it is mainly used in automobiles Stainless steel welded pipe. It is estimated that the stainless steel pipe used in automobile accounts for about % of the consumption of stainless steel pipe in the whole downstream. L stainless steel pipe, s stainless steel pipe and L stainless steel pipe are provided for a long time. The products are complete, excellent quality and favorable price. The use ratio of stainless steel pipe and welded pipe is about :.The operators are mainly plumbers and argon arc welders, with the cooperation of other types of work, and the argon arc welder shall have the certificate issued by relevant departments.

The experimental ice load of concrete decorated stainless steel pipe is the highest in the cold area(soft, / / h) and other primary and secondary stainless steel coils.Stainless steel grade group Series & mdash; Chromium nickel manganese austenitic stainless steel series & mdash; Chromium nickel austenitic stainless steel model & mdash; Good ductility, used for molding products. It can also be machined to harden rapidly. Good weldability. The wear resistance and fatigue strength are better than those of stainless steel.Quality assuranceStainless steel pipes can be divided into CR series ( Series), Cr Ni series ( Series), cold-rolled pipe, cold drawn pipe and pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.Stop the written technical disclosure, on-site technical and safety disclosure to the on-site operators.

Production process of stainless steel pipe A. preparation of round steel; b. Heating; c. Hot rolling perforation; d. Cutting head; e. Pickling; f. Grinding; g．； h. Cold rolling; i. Degreasing; j. Solution heat treatment; k. Straightening; l. Pipe cutting; m. Pickling; n. Finished product inspection.Standard requirements,BelmerbonStainless steel plate 443,Stainless steel pipe can be divided into equal section pipe and variable section pipe according to the profile shape. Variable section pipes include conical pipes, stepped pipes and periodic section pipes.According to the specification, the specification of stainless steel pipe is mainly based on gb- stainless steel seamless steel pipe. The general length (indefinite length) of precision stainless steel pipe and thick wall pipe is -m for hot-rolled steel pipe and m or more for hot-rolled steel pipe. The wall thickness of cold drawn (rolled) stainless steel pipe is .-mm and the length is -m; the wall thickness of stainless steel pipe is greater than mm and the length is -m.Proper heat treatment process can prevent intergranular corrosion and obtain excellent corrosion resistance.Belmerbon,When hoisting stainless steel pipes, public slings, such as hoisting belt and public collet number, shall be used. It is strictly prohibited to use steel wire rope to avoid scratching the surface; and when hoisting and placing, it shall prevent scratching caused by impact and collision. If there are surface scratches, electric arc traces and surface purification in the process of transportation, storage and processing, it must be completely cleaned, polished with an angle grinder, and then polished Polishing with optical sheet or metallographic sandpaper.Low temperature processing of stainless steel pipe --- martensite series stainless steel is quenched from austenitizing temperature and then cooled to very low temperature to promote martensite quenching. It is suitable for stainless steel easy to produce residual austenite.Model & mdash; Except that the risk of weld corrosion of the material is reduced due to the addition of titanium, other properties are similar. Stainless steel decorative pipe stainless steel pipe, series stainless steel pipe & mdash; Ferritic and martensitic stainless steel model & mdash; Good heat resistance, weak corrosion resistance, % Ni.
