        橡膠接頭的碳鋼法蘭和平焊法蘭介紹
            碳鋼法蘭:即本體材質為碳鋼的法蘭盤或末端法蘭聯接件。那邊邊含有碳鋼材質的法蘭,稱為碳鋼法蘭。常見材質為鑄造碳鋼牌號WCB、鍛件A105,或Q235B,A3、10#、#20鋼,16錳,45號鋼、Q345B等。
           
        Carbon steel flange: that is, the body material is carbon steel flange or end flange connection.The flange with carbon steel is called carbon steel flange.Common materials are cast carbon steel brand WCB, forging A105, or Q235B, A3, 10#, #20 steel, 16 manganese, 45 steel, Q345B, etc.

            平焊法蘭:符合運用于壓力等級比較低,壓力波動、振蕩及震動均不嚴重的管道系統中。平焊法蘭有點在于平焊法蘭焊接裝配時較易對中,況且價格比較便宜。平焊鋼法蘭符合運用于公稱壓力不超過2.5MPa的優質碳素鋼管道聯接。平焊法蘭的型式除對焊法蘭外,還有鑄鋼法蘭、鑄鐵法蘭等。對焊法蘭標準除GB9119.7-88外,常用標準還有:化工部標準HG20592~HG20602-97;中石化標準SH3406-96等。
            
        Flat welded flanges: suitable for use in piping systems where pressure levels are relatively low and pressure fluctuation, oscillation and vibration are not serious.Flat welding flange a little bit in the welding and assembly of flat welding flange is easier, and the price is cheaper.Flat welded steel flanges shall be suitable for use in quality carbon steel pipe connections with nominal pressure not exceeding 2.5mpa.Flat welding flange type in addition to butt welding flange, there are cast steel flange, cast iron flange.Welding flange standards in addition to gb9119.7-88, the commonly used standards are: the ministry of chemical industry standards HG20592 ~ hg20602-97;Sinopec standard sh3406-96, etc.
