San-Marcos219 stainless steel pipeHow to quickly occupy the commanding heights of the market

Welding of stainless steel pipe argon arc welding stainless steel pipe: it is required to have deep penetration,San-Marcos304 steel gas pipe is of good brand, no oxide inclusion, and the heat affected zone can be as small as possible. Argon arc welding maintained by tungsten inert gas has good compliance, high welding quality and good penetration function. Its commodities are widely used in chemical, nuclear and food industries.Chloride ions exist in the service environment. Chloride ions exist widely, such as salt, sweat, sea water, sea breeze, soil, floating rust of iron foam and so on. Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary low carbon steel. Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry. (in this way, the container leaks due to corrosion days after it is replaced with stainless steel.San-Marcos,After the installation of stainless steel water pipe cleaning pipeline, it is recommended to use % potassium permanganate for disinfection. It is strictly prohibited to use bleaching water for disinfection, and clean it with clean water after disinfection. If it is not put into use for a short time, compressed air must be used to blow out the residual water in the pipe, so as to prevent the corrosion reaction between oxygen free in the pipe and other media.Model & mdash; Commonly used precipitation hardening stainless steel model, usually also called -; %Cr,%Ni.GranvilleBrinell hardness in stainless steel pipe standards, Brinell hardness is widely used, and the hardness of the material is often expressed by indentation diameter, which is intuitive and convenient. However, it is not suitable for steel pipes with hard or thin steel.Stainless steel, precipitation hardening stainless steel and high alloy with iron content less than % are usually named by patent name or trademark.Austenitic stainless steel. It contains more than % chromium about % nickel and a small amount of molybdenum, nitrogen and other elements. Good comprehensive performance and resistance to corrosion of various media.

With the implementation of China's reform and opening up titanium,San-Marcos625 stainless steel plate, and a large number of urban houses, public buildings and tourism facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing. Galvanized steel pipe, a common pipe, will gradually withdraw from the historical stage under the influence of relevant countries because of its corrosivity. Plastic pipe, composite pipe and copper pipe have become common pipes in the pipeline system. However, under certain circumstances, stainless steel pipe has more advantages, especially the stainless steel pipe with wall thickness of only . ~ mm. In high-quality drinking water system, hot water system and water supply system that puts safety and sanitation first, it has the characteristics of safety, sanitation, environmental protection, economy and applicability. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environmental protection pipes with good comprehensive performance of water supply system. It is also a very competitive water supply pipe,San-MarcosDN50 stainless steel pipe, which will play an incomparable role in improving water quality and people's living standards.The shielding gas is argon with a purity of %. When the welding current is ~ a, the argon flow is ~ lmin, and when the current is ~ A, the argon flow is ~ lmin.Stainless steel seamless steel pipe for structure (instead of gbt-)market price,Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.Ferritic and martensitic stainless steels are represented by series numbers. Ferritic stainless steel is marked with and , martensitic stainless steel is marked with and C, dual phase (austenite ferrite).Various welding methods of combined welding stainless steel welded pipe have their own advantages and disadvantages. Combined welding methods include argon arc welding plus plasma welding, high-frequency welding plus plasma welding

Application field: launch the market plan of stainless steel pipe in the target market of new products such as stainless steel kitchen equipment.average method,Model & mdash; Add a small amount of sulfur and phosphorus to make it easier to cut.Oxygen plus gas flame can not cut stainless steel plate because stainless steel is not easy to be oxidized.It has the characteristics of high efficiency and low cost. At the same time, we use this method to weld joints and repair joints, with a one-time qualified rate of welding), which is worthy of our use.San-Marcos,Proper heat treatment process can prevent intergranular corrosion and obtain excellent corrosion resistance.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.Model & mdash; It has better temperature resistance.
