Stainless steel pipe, which was consumed and used at the end of the 1990s, is a rebirth group emerging in today's 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, so as to facilitate further implementation. In order to promote stainless steel pipe, since the 1990s, 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,430 mirror stainless steel plate, due to the glorious history of galvanized steel pipe, all kinds of new plastic pipes and composite pipes have been lost and developed rapidly, 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, especially the stainless steel pipe with wall thickness of only 0.6 ~ 2mm 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, which will play an unparalleled role in improving water quality and improving people's living standard.
The application of stainless steel pipe in the automobile industry is developing rapidly. In recent ten years, stainless steel pipe materials have been widely used in public transportation tools such as buses, subways, high-speed railway vehicles, household cars and so on!
Installation materials.5: 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, professional stainless steel plate, stainless steel coil, stainless steel belt, stainless steel pipe and other special products. It is a 20-year-old brand with 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 1500-2000. The hardness of spring wire is as follows: fully soft | 1 / 4 hard | semi hard | 3 / 4 hard | fully hard | extra hard. Steel wire rope gauge: 7 * 1,6 * 12,7 * 7,7 * 19,17 * 39,Nickel plated stainless steel strip, etc., which is higher than that of wires, rods and tubes of the same material, 304 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 13 chromium steel, 18-8 chromium nickel steel and other high alloy steels.
The cold working process performance and cold forming performance are much better than that of ferritic stainless steel.
Stainless steel pipe will not rust but it is relatively not easy to rust. It will rust in a specific environment. It will rust if placed in seawater or acid-base environment. Even in the air, it will be corroded and oxidized slowly but it will take a long time. In general, stainless steel pipes will not rust. However, if the stainless steel pipe is used or maintained improperly, or the environment in which the stainless steel pipe is located is too bad, the stainless steel pipe may rust. When we see rust spots on the steel surface we can quickly confirm that it is a sign of rust. Why does stainless steel pipe rust? First of all, let's understand the structure of stainless steel pipe: stainless steel pipe is a crystal solid composed of atoms similar to a piece of toys. In addition to iron, it also contains its metal components, such as chromium, nickel titanium, etc. Chromium and nickel have anti rust function. It forms a protective film - passive film to prevent stainless steel pipe from rusting. Generally, as long as the film is not damaged, broken or contaminated by impurities, the stainless steel pipe will not rust. However if the blunt film is damaged due to improper use or maintenance, the stainless steel pipe will rust.
500 Series & mdash; Heat resistant chromium alloy steel.
Executive standard. ·Rotary shaft, press roller, blade, etc. in high-strength corrosion-resistant environment.
The surface resistance is less than 1000mb; Wear protection; Scalable; Excellent chemical resistance; Good alkali metal and acid resistance; Strong toughness; Flame retardant.
The surface of stainless steel contains acid, alkali and salt substances (such as alkali water and lime water splashing on the decoration wall), which leads to local corrosion.
.According to the specification, the specification of stainless steel pipe is mainly based on gb14975-94 stainless steel seamless steel pipe. The general length (indefinite length) of precision stainless steel pipe and thick wall pipe is 5-10m for hot-rolled steel pipe and 1m or more for hot-rolled steel pipe. The wall thickness of cold drawn (rolled) stainless steel pipe is 0.5-0mm and the length is 0-7m; the wall thickness of stainless steel pipe is greater than 0mm and the length is 5-8m.
Clamping operation the jaw of the caliper must be placed perpendicular to the axis of the pipe and pipe fitting, and the convex ring of the pipe fitting needs to be put into the groove of the jaw for clamping. In order to prevent operation, the operator can only stand on the axis of the pipe, not on the left and right sides of the tong head.
Check 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 DN25 is slightly smaller than the outer diameter of the pipe, ranging from 0.1-2mm. The larger the pipe diameter, the greater the difference.
