It plays an important role in stimulating China's economic growth. However, from the current situation of China's stainless steel foreign trade China's stainless steel export has encountered great resistance.Siegen, it is mainly divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure fertilizer pipe, which was produced and used in China at the end of the s of which . is a constant converted from stainless steel density.Stainless steel pipe, is a new family emerging in the field of pipe materials. It has been widely used in building water supply and direct drinking water pipelines.Costa-Rica,Siegen316 stainless steel pipe manufacturer,That is stainless steel. The GB brand is CrNi. & mdash; it has better temperature resistance than it.The back is not protected by argon, and the flux cored wire + TIG process has been applied in China for several years. Flux cored wires such as et-elt-et-elt-t-et-elt- have been produced and applied to field welding, and good economic benefits have been obtained.Welding, high frequency preheating plus three torch argon arc welding, high frequency preheating plus plasma argon arc welding. The progress of combined welding is very significant. As for the combined welding of steel pipe with high-frequency preheating, the weld quality is equivalent to the conventional argon arc welding and plasma welding, the welding operation is complex, and the whole welding is easy to complete automation. This combination is easy to connect with the existing high-frequency welding equipment, with low investment cost and good benefit.

Marking: in order to make the steel pipe complete the socket of the pipe fitting, the length must be marked and marked at the pipe end.The external anti-corrosion coating of stainless steel shall be galvanized and epoxy asphalt coating or coating with higher requirements according to the soil conditions of the pipe laying ground.Model & mdash; General model; stainless steel. The GB brand is CrNi.Market trend,Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection (i.e. solid core welding wire + TIG + water-soluble paper)Austenitic stainless steel heat treatment austenitic stainless steel commonly used heat treatment processes are: solution treatment, stabilization treatment and stress relief treatment.The selection of pipes and fittings for welding data preparation shall be based on the quality elements of the application environment, and the commodities of corresponding grades shall be selected to ensure the weld metal structure and machine function.

When the stainless steel pipe with solid core welding wire is prefabricated, the welded junction can usually be rotated for welding, and the ventilation is very easy. At this time, the blocking plate is usually used to block both sides of the welded junction in the pipe, and the bottom welding is carried out for the protection of ventilation (see Table ), and the outside is blocked with adhesive cloth.Work courses,. Domestic wce cerium tungsten electrode is used for electrode data. The shape and diameter of the end of cerium tungsten electrode have a great impact on the fluctuation of welding process and weld formation.Stainless steel pipe appeared in Foshan, Guangdong Province in the tenth generation of the last century. With the rapid development of science and technology in recent decades, stainless steel pipe production is all over the country. Stainless steel pipe is more and more widely used. But in fact, most people, including many people in the industry, do not know much about the classification and application of stainless steel pipes. Take stainless steel pipe for example.Stainless steel pipe factory stainless steel products are widely used in hardware products, furniture, mechanical accessories, precision medical instruments, fluid transmission pipelines, such as furniture, machinery, medical oil, natural gas, water, gas steam and other industries.Siegen,Accounting for about % - % of the total steel, it is widely used in the national economy. Because the steel pipe has a hollow section, it is suitable for gas and solid transmission pipelines; at the same time, compared with the round steel of the same weight, the steel pipe has large section coefficient and high flexural and torsional strength, so it has also become an important material in various machinery and building structures. Stainless steel is used Under the condition of equal weight, the structure and components formed by pipe have a larger section modulus than solid parts. Therefore, stainless steel pipe itself is an economic section steel that saves metal. It is an important part of steel, especially in oil drilling, production and metallurgy Series & mdash; martensitic precipitation hardening stainless steel pipe.For more than years, architects have been using stainless steel to build cost-effective buildings. Many existing buildings fully illustrate the correctness of this choice. Some are very ornamental, such as the Chrysler Building in New York City. However, in many other applications, the role of stainless steel is not so eye-catching, but in the aesthetics and performance of buildings For example, because stainless steel has more wear resistance and pressure resistance than other metal materials of the same thickness, it is the preferred material for designers when building sidewalks in places with large population flow.
