Carbon steel flange is made of the material production of carbon steel flange, and flange, is a kind of used to connect piping accessories. Carbon steel flange (flange) material general allowance is 10% 10% of the theory of the flange thickness flange thickness and the smaller the diameter D, delta and section steel flange (flange) need to be normalizing + tempering heat treatment, machining port. And the better the performance of mold joint, the easier arc instability in the flange wrinkling.

Connections are welding, thread, the three CARDS.

Production technology in forging, casting, medium plate rolling, the plate cutting, etc. Second forging of the highest prices, medium plate products, casting products are the lowest. Carbon steel flange (flange) the principle of determining the heating temperature is above material austenitizing temperature. The higher the heating temperature. The higher the material yield limit of high temperature, the higher the heating temperature.

Carbon steel flange (flange) standard has the mechanical standard JB/T81-94, chemical standard HG20593-97, HG20617-97, the national standard GB/T9119-2000, Marine standard CB M1001-81, thermal power D - GD87-1101 standard. Carbon steel flange (flange) insulation joint, used in stainless steel and carbon steel connection joint, domestic dissimilar steel material change, like direct dissimilar steel welding, as well as through the flange connection, but did not consider different potential difference between the two materials, corrosion potential difference will exist. Domestic design seems to be no more attention to this, foreign projects are basically take this connection, carries on the insulation.

Compared with ordinary carbon steel flange (flange) made of Q235B, 20 #, 16 mn, 45 # steel, Q345B material, etc. The main origin division MengCun County in hebei province and Shanxi Province dingxiang county area. Right angles to the carbon steel flange is black color, amount, quality, wear resistance, not easy to damage. Carbon steel flange (flange) specifications for 1/2-10 inch, products widely used in petroleum, chemical industry, metallurgy, electric power industries such as pipeline, equipment and supporting services. And generally do not add a lot of alloy element in steel, carbon steel mainly refers to the mechanical function depends on the carbon content in steel. Sometimes referred to as the carbon steel or carbon steel. Carbon steel or carbon steel, carbon content W3 is less than 2% iron carbon alloy.
