For the length of welding arc， ~ mm is better for ordinary steel welding and ~ mm is better for stainless steel welding. If it is too long， the protection effect is not good.
0According to rolling it can be divided into hot rolled， hot extruded and cold drawn (rolled) stainless steel pipes.
uModel & mdash; The corrosion resistance is the same， and the strength is better because the carbon content is relatively high.
Stainless steel pipe is a long strip of steel with hollow section and no joints around it. The thicker the wall thickness of the product， the more economical and practical it is. The thinner the wall thickness the higher its processing cost will be.
FShahemone(I) The output reached a record high. From January to June，304 stainless steel plate ，Benxi 304 stainless steel platebuild the country produced million tons of crude steel， an increase of % year-on-year， an increase of percentage points over the same period last year. In the first six months， the average daily output of crude steel was tons， equivalent to the level of . billion tons of crude steel. Among them， it reached a record high of . million tons in February. Although it fell from March to June， it still remained at a high level of more than . million tons. From January to June， according to provinces and regions The crude steel output of Hebei and Jiangsu increased by % and % respectively year-on-year. The total new output of the two provinces accounted for % of the national increase of . million tons. In addition， the output of Shanxi，304 stainless steel plate Henan and Yunnan also increased by more than million tons. According to the types of enterprises， percentage points lower than the national average increase. They specialize in the sales of L stainless steel pipes and s stainless steel pipes Stainless steel pipe， L stainless steel pipe has high pressure resistance grade， good waterproof performance， fire resistance， high temperature resistance， strong overload capacity， corrosion resistance， radiation protection and long service life. However， it is still years old
HaThe cold working process performance and cold forming performance are much better than that of ferritic stainless steel.
After the pipeline is installed and the pressure test is qualified，304 stainless steel plate it is better to wash with low chloride ion water and disinfect with .% potassium permanganate.
The stainless steel strip is supplied in coils， also known as strip steel. It is divided into hot rolling and cold rolling，Benxi 304 stainless steel platebuild as well as ordinary steel strip and high-quality steel strip. There are many kinds of stainless steel belts!

Tquality indexCharacteristics and application h austenitic stainless heat strength steel has good corrosion resistance， welding performance and heat strength performance. h stainless steel is used for large boiler superheater， reheater， steam pipeline and petrochemical heat exchanger pipe fittings.
bPStainless steel pipe water supply pipe is a healthy， economic， sanitary and energy-saving water pipe. It is the best choice for both domestic and large engineering buildings. It is also frequently launched in the market. If you want to buy a stainless steel pipe water supply pipe with quality assurance， we should choose carefully and should not buy them at a low price. However， the transmission energy consumption of stainless steel pipe water supply pipe is low， which saves the transmission cost， so the price will not be too expensive.
Usage: it is widely used in automobile industry， aviation industry and other departments.
Product linelAccording to rolling， it can be divided into hot rolled， hot extruded and cold drawn (rolled) stainless steel pipes.
TStainless steel pipe， which was consumed and used at the end of the s， is a rebirth group emerging in todays pipe range. It has been widely used in the construction of water supply and direct drinking water pipelines. Stainless steel pipe is durable and has been recognized by the engineering community， and relevant parties are starting from reducing the wall thickness and reducing the price， so as to facilitate further implementation. In order to promote stainless steel pipe， since the s， China has started to reduce wall thickness and cost; High diameter to wall ratio and high precision & rdquo; The technical effect of stainless steel pipe makes the stainless steel pipe lose its application and expand quickly. There are various connection modes of stainless steel pipes. The rare types of pipe fittings include contraction type， compression type， union type， push type， push thread type， socket welding type， union flange connection， welding type and derivative series connection mode combining welding with traditional connection. These connection methods have different application ranges according to their principles， but most of them are convenient， firm and reliable. The sealing ring or gasket materials used for connection are mostly silicone rubber， nitrile rubber and EPDM that meet the requirements of national specifications， which eliminates the worries of users. In the construction of water supply pipe system， due to the glorious history of galvanized steel pipe， all kinds of new plastic pipes and composite pipes have been lost and developed rapidly， but they are far from fully meeting the needs of water supply pipe system and the national requirements for drinking water and related water quality. In direct drinking water， stainless steel pipe system is undoubtedly one of the best. At present， hotels and public places at the international level have been equipped or are equipped with direct drinking water pipelines. In many cases， stainless steel pipe has more advantages， especially the stainless steel pipe with wall thickness of only . ~ mm has the characteristics of safety， reliability， sanitation， environmental protection， economy and applicability in high-quality drinking water system， hot water system and water supply system that puts safety and sanitation first. It has been proved by engineering theories at home and abroad that it is not only one of the new， energy-saving and environmental protection pipes with good comprehensive function of water supply， but also a very competitive water supply pipe， its wear-resistant corrosion and fatigue corrosion properties are better than austenitic stainless steel.
uGCheck the clamping forming effect after each clamping and there shall be no clamping in place or serious depression of pipe clamping. According to visual inspection， the pipe fitting end and the pipe are tightly bonded. The smaller the diameter of the diamond edge of the pipe fitting above DN is slightly smaller than the outer diameter of the pipe， ranging from .-mm. The larger the pipe diameter， the greater the difference.
As we all know， stainless steel pipe has a strong ability of atmospheric oxidation and is not easy to rust under normal circumstances， & ldquo; Stainless steel pipe & rdquo; Hence the name of. But what I want to tell you today is rust
