We supply all kinds of carbon steel lap joint flange with standard ANSI B16.5, DIN and EN1092.
Specification of carbon steel lap joint flange
Standard of carbon steel lap joint flange：ANSI B16.5,ANSI B16.47, DIN,EN1092
Material of carbon steel lap joint flange：ASTM A105,105N,20Mn,St37.2,Q235,S235jg
Surface Yellow Black Paint or Antidust Oil
Pressure of carbon steel lap joint flange: 150-1500Lbs, PN10/16, 5K,10K
Technology of carbon steel lap joint flange:Forged
Size 1/2-72''
Face :FF RF LJ RTJ TG
Marking:according to customers need
Examples of drawings of carbon steel lap joint flange are as follows:
carbon steel lap joint flange are shaped to accommodate the stub end. The combination of flange and stub end presents similar geometry to the raised face flange and can be used where severe bending stresses will not occur. The carbon steel lap joint flange is economical if costly pipe such as stainless steel is used because the flange can be carbon steel, and only the lap joint stub end needs to be furnished in the line material. A stub end is used in a lap joint, and the cost of the two items must be considered. If both stub end and flange are of the same material, they would be significantly more expensive than a weld neck flange.
When selecting carbon steel lap joint flanges, it should be noted that the moisture in the arc column atmosphere, the flange welding data and the moisture adsorbed by the oxide film on the base metal surface are important sources of hydrogen in flange welding. Therefore, the source of hydrogen should be strictly controlled to avoid the formation of pores.
