Katherine source Pipe Co., Ltd. Liaocheng standing resource material for the: 20 #, 45 #, 16mn, [Q235B, C, D,] Q235, A, B, C, 27simn 20G, 20mn2,45mn2, PII, P22, T91, cr5mo , 35crmo, 42crmo, 12cr1mo, 15cr1mo, 10crmo910, and so on. Implementation of standards; structural tubes GB8162--1999, fluid management GB8163--1999, low-pressure boiler pipe GB3087-1999, high alloy pipe GB5310-1995 fertilizer tube GB6479--2000, oil cracking pipe GB9948--88, gas GB18248--2000 seamless steel bottles and so on. P91 Alloy uses 1, P91 alloy tube is so widely used. P91 alloy tube for general use by ordinary carbon steel, low-alloy structural steel or alloy steel rolling into production up to T91, mainly used for transporting fluids or structural components. 2, depending on the use of three types supply: a, according to the chemical composition and mechanical properties supply; b, according to the mechanical properties of supply; c, according to hydrostatic testing supplies. Press a, b class supply pipe, such as to withstand the liquid pressure, but also pressure test. 3, P91 alloy tube boiler with a special purpose P91 alloy tube, geology and petroleum with P91 alloy pipe seamless pipe and other. The main alloying elements FSC specifications silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth alloy steel tube in addition to iron, carbon, and a small amount of non- Avoid beyond silicon, manganese, phosphorus, sulfur, also contain a certain amount of alloying elements in steel alloying elements which silicon, manganese, molybdenum, nickel, Ge, alumina, titanium, niobium, boron, lead, and other rare earths one or more of T91, each of the steel alloy called alloy systems, with their own resources, production and use vary conditions abroad in the past has been the development of nickel, steel Ge system, the discovery of silicon, manganese , vanadium, titanium, niobium, boron, lead, rare earth-based steel alloy systems account for about ten percent of the total production in the steel, usually in an electric furnace smelting of steel pipe by use can be divided into eight Tianjin categories T91, they are: alloy structural steel, spring steel, bearing steel, alloy tool steel, high speed tool steel, stainless steel, heat-resistant steel can not afford leather, electrician has good formability silicon steel PC / ABS, may Processing large automotive parts such as automobile fenders, there is a very high price in the ordinary carbon steel alloy steel pipe on the basis of one or more alloying elements to add the right amount and classification of iron-carbon alloy steel tube constituted: P91 alloy steel points tube and welded steel pipe. Of Island T91, T91, Katherine source of steel provided by source Pipe Co., Ltd. Liaocheng trillion. Liaocheng Katherine source Pipe Co., Ltd. (www.lczygg.com) strong, credible, Liaocheng in Shandong steel industry has accumulated a large number of loyal customers.
