8At this time， we usually answer directly: no! What we produce is stainless steel decorative pipe， which belongs to stainless steel slotted pipe. It can not be used as stainless steel water pipe. If you want to choose stainless steel water pipe， you must choose stainless steel pipe.
zThe back is not protected by argon， and good economic benefits have been obtained.
Under the corrosion condition of plasma arc cutting， there are dust containing other metal elements or attachments of dissimilar metal particles on the surface of stainless steel. In humid air，stainless steel sheet causing electrochemical reaction and damage to the protective film，2m stainless steel plateOxidation resistance of which is called electrochemical corrosion.
FNajinWhen selecting stainless steel water supply pipe， carefully observe whether the surface of the pipe is shiny， damaged and crushed， and pay attention to whether the incision is neat. If these phenomena occur， they should be carefully considered.
SeFor 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.
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 sheet 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.
The power supply with vertical external characteristics is adopted， and the positive polarity is adopted in DC (the welding wire is connected to the negative pole).
mStop the written technical disclosure， on-site technical and safety disclosure to the on-site operators.
VFor the manual clamping tool， the upper and lower jaw are fixed modules， and the pressure is set to output a constant pressure of MPa. The detection standard is to observe the seam of the upper and lower jaw and press it once or twice.
Zsafety requirements Check whether the sealing ring of pipe fittings is complete and clean and whether the placement position is correct. If there is dirt， it must be cleaned up. If the sealing ring is damaged it must be replaced again.
cNQuality: different steel strip materials determine the quality of stainless steel， which is a major factor affecting the price of stainless steel at present.
Choose the price.
Quality managementzShop around and choose affordable stainless steel water supply pipes. Compared with the prices of pipes sold by various companies，stainless steel sheet 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，2m stainless steel plateOxidation resistance of which saves the transmission cost， so the price will not be too expensive.
AAt the same time， the Ministry of construction attaches great importance to the promotion and application of stainless steel pipes. The industry standard of stainless steel water pipe was issued and implemented in . The Ministry of construction has issued documents on relevant technical specifications and installation sets of pipeline engineering， which are being prepared by Tongji University. Sales of all kinds of stainless steel plate， stainless steel coil stainless steel belt， stainless steel pipe formal qualification， welcome to telephone inquiry， sincerely invite cooperation! At present，tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd there are stainless steel pipes in Sichuan， Guangdong， Zhejiang， Jiangsu and other places， and the products have become mature. Therefore， the time for popularization and application has come.

h. Distinguish between L and L. There are two kinds of commonly used stainless steel l (or corresponding to the German / European standard l， the main difference in chemical composition between L and is that L contains Mo， and it is generally recognized that has better corrosion resistance than in high temperature environment. Therefore， engineers generally choose L parts in high temperature environment. However， this is a big problem. People who study mechanics have all studied threads. Remember a black solid lubricant that needs to be applied to prevent threads from biting at high temperature: molybdenum disulfide (MOS) L should not be used at any higher temperature! No However， from which two conclusions are drawn: No:  Mo is indeed a high-temperature resistant material (know what crucible gold is melted in? Molybdenum crucible!).  : molybdenum can easily react with high valence sulfur ions to form sulfide. Therefore， stainless steel is a steel with more impurities (but these impurities are more corrosion resistant than steel). If it is steel， it can react with other substances.
zR: stainless steel wire: it can also be called stainless steel wire， coil rod and coil yuan， but it is different from stainless steel wire rope. Wire rod mainly includes spring wire and screw wire. It specializes in selling special products such as stainless steel plate， stainless steel coil， stainless steel belt and stainless steel pipe. The old brand has advantages in price and guaranteed quality. As the name suggests: screw wire is mainly used to make screws， The spring wire is used to make springs or other hardware products required. Others， such as bright wire hydrogen withdrawal wire， electrolytic wire， axle hairpin wire， etc. the tensile strength is -. The hardness of spring wire is as follows: fully soft | / hard | semi hard | / hard | fully hard | extra hard. Steel wire rope gauge: * ， * ， * ， * ， * ， which is higher than that of wires， rods and tubes of the same material， stainless steel is a kind of high alloy steel that can corrode in air or chemical corrosion medium. Stainless steel has beautiful surface and good corrosion resistance. It does not have to go through surface treatment such as color plating， but gives full play to the inherent surface properties of stainless steel. It is used in many aspects of steel， which is usually called stainless steel. Representative properties include chromium steel， - chromium nickel steel and other high alloy steels.
In the past few years， the United States has imposed anti-dumping and countervailing duties on a variety of steel pipe products exported from China， including ring welded pipe， rectangular pipe， small-diameter pipeline pipe， welded stainless steel pressure pipe， oil well pipe and seamless steel pipe. These foreign double back pressures have greatly reduced the number of steel pipes exported by China.
