<p> Basic knowledge of Guilin Qixing Q610L square tube sanitary mirror tube process: quality standard Guilin Qixing 3 317 stainless steel pipe has a slightly higher molybdenum content than 316 stainless steel pipe. Due to the molybdenum in steel, the overall performance of this steel grade is excellent In 310 and 304 stainless steel, under high temperature conditions, when the concentration is lower than 15% and higher than 85%, Guilin Qixing q690d square tube, 316 stainless steel has a wide range of uses. The reason why this product appears in the new product market is mainly because the good people are eager to smoke, and the old lack of awareness of stainless steel has been carried out. It is generally believed that stainless steel is non-magnetic, and a large number of manganese-nickel substitution methods are used, and Guilin Qixing b510l square tube is used to change the composition of the product to obtain a material that is neither magnetic nor extremely low-cost, thereby achieving the goal of high profits. . Quality management is used by other departments in Qitaihe. Such as: container tube (high pressure gas cylinder tube and general container tube), instrument tube, watch case tube, injection needle and its instrument tube. Reasonable price formula for seamless steel pipe weight: 4X wall thickness * (side length-wall thickness) x 85 basic knowledge of Guilin Qixing Q610L square pipe product Q345 seamless steel pipe is a kind of steel pipe material. Q stands for the yield of this material. The following 34 refers to the yield value of this material, which is around 345. And as the thickness of the material increases, its yield value decreases. The quality inspection report is that for large threads with a diameter of 16 or more steel pipes, the spacing between the two trademarks is above IM. Profession is king </ p> <p>

</ p> <p> Basic common sense of Guilin Qixing Q610L square pipe product Cold drawn (rolled) seamless steel pipe: round pipe blank → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass Sub-cold drawing (cold rolling) → billet tube → heat treatment → straightening → hydraulic test (detection) → marking → storage. "Hot-rolled thick-walled seamless steel pipe", "Cold-rolled thick-walled seamless steel pipe", "Cold-drawn thick-walled seamless steel pipe", "Thick-walled seamless steel pipe", "Stainless steel seamless steel pipe for pipe jacking structure" (GB / T14975-200) is a seamless steel pipe for general structure and mechanical structure, which is widely used. Suitable for hot-rolling of corrosion-resistant pipes and stainless steel parts in chemical, petroleum, textile, food, machinery and other industries. (Extrusion, expansion) and cold drawn (rolled) seamless steel tubes. The functional index analysis of Q195 welded seamless steel pipe-the strength, plasticity and angle discussed behind the toughness of the charge array are all machine function gauges under the static load. In practice, many mechanical machines are under repeated load employment, and in this environment, the whole machine is tired. Seamless steel tubes are classified by wall thickness-ultra-thick wall seamless steel tubes, thick wall seamless steel tubes and thin wall seamless steel tubes. Guilin Qixing Diesel High Pressure Oil Pipe (GB3093-8 is a cold drawn seamless steel pipe for high pressure pipes of diesel engine systems. Inquiry (a) According to process-arc welded pipe, resistance welded pipe (high frequency, low frequency), gas welded pipe, furnace welded pipe (b) According to weld seam-straight seam welded pipe, spiral welded pipe according to section shape and wall thickness- Thin-walled steel pipes and thick-walled steel pipes are classified according to their use-Process pipe for thermal equipment, steel pipe for machinery industry, steel pipe for petroleum, geological drilling, container steel pipe, steel pipe for chemical industry, special purpose steel pipe, other sanitary grade mirror pipe.

Ti≤0.20, Cr≤0.30, N≤0.0 Mo≤0.10 As of 2008, Foshan, Guangdong Province has reached nearly 200 manufacturers of good decorative tubes, with an output of about 1 million tons. Except for a few companies such as Lanshi Yuhangxing, most of them are stainless steel tubes with 304 tube materials. The ratio of 304 and 201A output is about 1: 9. Sincere service Huaihua physical properties: Critical point temperature (approximate value): Ac1 = 730 ° Ac3 = 800 ° Ms = 310 ° C. Basic knowledge of Guilin Qixing Q610L square tube product Q345b None A seam seamless steel pipe is a long strip of steel with a hollow section and no perimeter. The steel pipe has a hollow cross section, and is widely used as a pipeline for transporting fluids, such as a pipeline for transporting oil, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight with the same flexural and torsional strength. It is an economical cross-section steel and is widely used in structural parts and mechanical parts, such as petroleum drill rods, automotive transmission shafts, bicycle frames, and Steel used in building construction. System 9 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel and can be used in the above temperature range. Service first </ p> <p>

</ p> <p> Basic common sense of Guilin Qixing Q610L square pipe products, the original state of steel, that is, the delivery status of steel pipes, can be divided into (in parentheses): cold working / hard (BK), cold working / soft (BKW) , Stress Relief Annealing (BKS), Tempering (GBK), Normalizing (NBK). The commonly used state is the annealed state, which facilitates subsequent processing. Quality Management GB3087-2008 "Seamless Steel Pipe for Low and Medium Pressure Boilers". The chemical composition test is in accordance with the relevant parts of GB222-84 and GB223 "Chemical Analysis of Steel and Alloys". Advantages 2 Welded 304 stainless steel pipe can suppress carbide precipitation during welding, and can be used for general welding. Manual arc welding, 304 stainless steel with 0.04% -0.06% carbon in thin section size can use Austria 002 electrode, after welding, there is no tendency of intergranular corrosion. For thick section rule, to maintain the intergranular corrosion resistance after welding, After welding heat treatment, if not heat treatment, it should be changed to 304L stainless steel or stable austenitic stainless steel. In recent years, with the investment in basic construction, major municipal and construction projects in various places have increasingly adopted the form of steel structures, and large-scale thick-walled seamless steel rectangular pipes are relatively beautiful due to their beautiful appearance and reasonable force, and the joint processing is relatively small. Simple and other advantages, so it is widely used as steel members in the truss structure and curtain wall support of airport terminals, stadiums and exhibition centers. However, in practical applications, square rectangular steel pipes also encountered some problems that needed to be solved urgently. Seamless seamless steel tubes are square-angle steel tubes. Square steel tubes formed by seamless drawing of seamless steel tubes. There is an essential difference between seamless seamless steel tubes and welded seamless steel tubes. The steel pipe has a hollow cross section and is used in large quantities as a pipeline for conveying fluids. Average structure pipe GB8162-2008 fluid pipe GB8163-2008 medium and low pressure boiler pipe GB3087-2008 high pressure boiler pipe GB5310-2008 fertilizer special pipe GB 79-2000 petroleum cracking pipe GB9948-88. Low alloy seamless steel pipe English: (Low alloy square tube) is a kind of square pipe, Guilin Qixing Q460C square pipe, which is the same length of steel pipe. The low-alloy seamless steel pipe executes the standard GBT 6728-2002 cold-formed hollow section steel for structure. The size, shape, weight and allowable deviation are good. It is made of Q345B strip steel after being processed. </ p>
