Clamping connection steps: cut off the pipe according to the required length. When breaking the pipe, it shall not be too large to prevent the pipe from being out of round.The method is that the heated tube blank is placed in a closed cylinder, and the perforated rod and rod move to extrude the part from the smaller die hole. This method can produce steel pipes with smaller diameter.Accounting for about % - % of the total steel,ZwevegemNational standard for stainless steel pipe, 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 metallurgyFair price,Production mode stainless steel pipe can be divided into seamless pipe and welded pipe according to the production mode. Seamless steel pipe can be divided into hot-rolled pipe, 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.Formula for hydraulic test pressure of stainless steel welded pipe for weight calculation fluid (gbt-): where: P - test pressure, MPa; R - stress, taking yield point of %, MPa; s - nominal wall thickness of steel pipe, mm; D - Nominal outer diameter of steel pipe, mm.Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.

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, avoid the machining platform of austenitic stainless steel and carbon steel or solid overhead.Installation materials,It has the characteristics of high efficiency and low cost. At the same time, it can also well ensure the welding quality (in the capacity expansion and reconstruction project of Urumqi petrochemical we use this method to weld joints and repair joints, with a one-time qualified rate of welding), which is worthy of our use.Cutting tool level & rdquo; Martensitic steel, an early stainless steel similar to Brinell high chromium steel.

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.Proper heat treatment process can prevent intergranular corrosion and obtain excellent corrosion resistance.
