Carbon Steel Flange
Carbon steel flange I. product introduction Carbon steel flange, that is, the body material for carbon steel flange or end flange connection. Which contains carbon steel material flange, known as carbon steel flange. Common materials are cast carbon steel WCB, forging A105, or Q235B, A3, 10#, 20 steel, 16 manganese, 45 steel, Q345B, etc. Ii. Product parameters Model Q41F - 16 c Q41F - 25 c The American standard A105 is about 0.9% (the standard is that 1.05Max can reach 1.65%Max with the decrease of carbon content). The content of 16Mn in the national standard is about 1.3% (the standard is 1.2% ~ 1.6%), and the content of daily standard S25C is lower than 0.6%. Iii. Product advantages Production process has forging, casting, plate rolling system, plate cutting system and so on. Among them forging price is the highest, medium plate product is the second, casting product is the lowest. In terms of quality, the best is forged, the second is rolled and the third is cast. But the forging diameter is generally small. Another layer of carbon steel flange means: According to the national standard size, the tolerance range, such as the production of flange, apart from not according to the standard size production of flange piece also said two standard flange (someone called non-standard flange is not correct), usually some unscrupulous merchants will reduce two flange thickness, diameter size to achieve the purpose of saving material, and made from scrap steel and scrap steel flange, is usually the steel chemical composition and mechanical properties of substandard waste, moreover steelmaking production flange with black steel private, the private steel steelmaking technology using old, there is no guarantee that the mechanical properties and welding performance, use which may not be able to and steel pipe welding, Or the steel itself has cracks, pores, and so on after welding will leak. So choose carbon steel flange when buying flange plate as far as possible. Carbon steel flanges are compact and reliable. It has two sealing surface, and the ball valve sealing surface materials are widely used in a variety of plastics, good sealing, can achieve complete sealing. Carbon steel flange can be used in medium with suspended solid particles because of its wiping property during opening and closing.

Alloy Steel Flange
Alloy steel flange is different from the common 20#, Q235 carbon steel flange, mainly used for special characteristics of pipelines and pipelines, more used for high temperature and high pressure position.Its common materials are 12Cr1MoV, 15CrMo, P91, P22, 10CrMo910 and so on.Alloy steel flanges can be divided into national standards (ministry of chemical industry standards, petroleum standards, power standards), American standards, German standards, Japanese standards, Russian standards and so on.Alloy steel flange of main resources and main application parameters are as follows: alloy steel flange of the reference standard, alloy welding neck flange manufacturing method choice, chemical composition analysis, mechanical performance, corrosion performance of detection, the main method of heat treatment, the tensile and hardness tests, alloy for the welding process in the process of installation. Alloy steel flange is one of the most widely used parts in petrochemical industry and is an important pipeline equipment in petrochemical industry.Butt welded flanges are used in pressure vessels and cryogenic vessels because of their excellent compressive stress and low temperature resistance.Alloy flanges have been used in chemical pipelines because of their corrosion resistance and oxidation resistance.In addition, by changing the content of chromium in alloy steel flanges and adding other alloying elements, it can also be used in ships, offshore oil exploration, aviation lights.
