For stainless steel precision tubes, we can see from the name that it has more precision than ordinary stainless steel tubes, so what is the difference between stainless steel precision tubes and ordinary tubes? Let's take a look at how Fuxin Pipe Industry introduces!   Zhejiang Fuxin Pipe Industry Co., Ltd. is mainly engaged in the production, processing and installation of steel pipes, pipe fittings, flanges and pressure vessels. The main materials are: Ha C276, 904L, incoloy800H, incoloy 926 steel, incoloy 600, steel Monel 400, 253MA , 254SMo, urea grade 725LN, 724L, 316Mod, 347, 317, 310, 321, 304, duplex steel 2205, 2507 and other series. The company selects Baosteel, Yongxing Special Steel, Taiyuan Iron and Steel, Walsin Lihua, Qingshan and other companies to smelt raw materials to provide safe and reliable stainless steel piping system products for global users.1. Pipe diameter tolerance   As we said above, stainless steel precision tubes have more words of precision, so the biggest difference between them and ordinary tubes is precision. Ordinary pipes are mostly used in decoration and industry, and the requirements for pipe diameter tolerances are relatively small, and the precision of pipe diameter tolerances is generally above ±0.1mm; stainless steel precision pipes are different from them. Within ±0.05mm.   2. Surface treatment   The surface treatment of stainless steel precision tubes is more stringent than that of ordinary tubes. Stainless steel precision tubes need to meet the following requirements:   1. No scratches and scars on the surface of the pipe.   2. The wall thickness is uniform and smooth, and the nozzle is complete without burrs.   3. The inner wall is smooth, there is no leaking sand hole in the weld, and the surface brightness is above 200 mesh.   Ordinary stainless steel tubes have a rough surface when they leave the factory, and secondary surface treatment should also be performed, so stainless steel precision tubes must be much stronger than ordinary tubes in comparison.   3. Performance   The commonly used materials of stainless steel precision tubes are generally 304 and 316L, while ordinary tubes are mostly made of 201 material, and 304 and 316L are rarely used. Therefore, stainless steel precision tubes are more prominent in material performance than ordinary tubes.   The company's production, sales and management are carried out in strict accordance with the requirements of ISO9001 international quality system certification. The company has been recognized by the same industry for its high-quality product quality, and is favored by domestic and foreign consumers for its affordable price.

Recently, the power plant of Liuzhou Iron and Steel Zhongjin Company completed the technical transformation of hot rolling wastewater treatment, which promoted the efficient use of wastewater, achieved an annual cost reduction of nearly 4 million yuan, and achieved a double harvest of "environmental protection benefits + economic benefits".   It is understood that after the plan was finalized, the power plant of CICC immediately organized maintenance personnel to connect and transfer the front and rear pipes, realizing the direct delivery of hot rolling wastewater to the sedimentation tank of the cast iron machine for use.   According to statistics, cast iron machines can save 200 tons of new industrial water per day, and reduce the cost of hot rolling wastewater treatment by about 3 million yuan per year.   At the same time, strengthen the real-time monitoring of hot-rolling wastewater, keep abreast of the water supply situation, and make timely and reasonable adjustments to further reduce the consumption of molten iron per ton.(Source: Liugang News)statement:The above content is reproduced from 51 stainless steel network, if there is any infringement, please inform and delete it.

Some manufacturers of stainless steel EP pipes on the market will spray the surface, so why is this? Is spraying necessary for EP pipes?   Zhejiang Fuxin Pipe Industry Co., Ltd. is mainly engaged in the production, processing and installation of steel pipes, pipe fittings, flanges and pressure vessels. The main materials are: Ha C276, 904L, incoloy800H, incoloy 926 steel, incoloy 600, steel Monel 400, 253MA , 254SMo, urea grade 725LN, 724L, 316Mod, 347, 317, 310, 321, 304, duplex steel 2205, 2507 and other series. The company selects Baosteel, Yongxing Special Steel, Taiyuan Iron and Steel, Walsin Lihua, Qingshan and other companies to smelt raw materials to provide safe and reliable stainless steel piping system products for global users. The main materials produced by our company are classified into duplex stainless steel, Hastelloy, austenitic stainless steel, urea grade steel, high temperature nickel base, iron base and other special alloys. All kinds of steel pipes, pipe fittings, flanges, heads, manholes, valves and other pipeline system accessories and non-standard customized metal parts products are widely used in petroleum, chemical industry, heat exchangers, nuclear power plants, railways, seawater equipment, environmental protection equipment, medicine Machinery, food machinery, shipbuilding and paper industry, sewage engineering, biological engineering and other industries.Generally speaking, stainless steel EP pipes do not need to be sprayed for the following reasons:   1. The function of spraying is mainly to prevent corrosion, and the stainless steel EP pipe itself has excellent corrosion resistance.   2. If the stainless steel EP pipe is sprayed, it is easy to be confused with the galvanized steel pipe.   3. Unless it is a customer's request, this process has no practical value.   The surface of the stainless steel EP pipe is smooth. If it is sprayed, it will fall off after a while, and it may also affect the appearance of the surface, so it is not necessary.

The processing of stainless steel EP pipe is very important. If the technology is immature or there are defects, it may lead to waste steel pipes, and the level of secondary processing characteristics will decline. Therefore, the following are some common processing problems about stainless steel EP pipes.1. The surface is inconsistent: only pickling and passivation is carried out on the welding, resulting in uneven surface and unsightly appearance.   2. Weld seam defects: Weld seam defects are relatively serious, and manual mechanical grinding is used, and the resulting grinding marks lead to uneven surface layers.   3. Scratches are difficult to remove: the overall pickling passivation cannot remove the scratches produced by processing, and it is also impossible to clean up impurities such as carbon steel and splashes adhered to the surface of stainless steel due to scratches and welding spatters, making them in corrosive media. In the presence of chemical corrosion or electrochemical reaction corrosion occurs.   4. Uneven passivation of grinding and polishing: Pickling and passivation treatment after manual grinding and polishing is difficult to achieve a uniform and consistent effect on large-area workpieces, and the cost of labor and auxiliary materials is relatively high.   5. The ability of pickling is limited: the pickling passivation paste is not complete, and it is difficult to remove plasma cutting, flame cutting and black oxide skin.   6. Scratches caused by human factors: In the process of lifting, transportation and structural processing, the scratches caused by human factors (knocking, dragging, hammering, etc.) important reason.
