What is anti-corrosive flange?
Anti-corrosive flange is the flange adopted by coating,galvanizing and other anti-corrosive measures.Anti-corrosive flange can be divided into container flange and pipe flange according to the parts connected.According to the structure there are integral flange,lap joint flange and threaded flange.The production process of anti-corrosive flange is mainly divided into forging,casting, cutting and rolling.
Flange coating with interthane-990 Polyurethane
Large-scale anti-corrosive flange mainly adopts radiation cross-linked polyethylene thermal shrinkage belt anti-corrosive process.Radiation cross-linked polyethylene thermal shrinkable tape is a new kind of anti-corrosive material with good performance and easy operation. It is composed of base material and hot melt adhesive layer.The material of large anti-corrosive flange is mainly carbon steel,which is suitable for oil and gas transportation engineering and chemical industry.
The large anti-corrosive flange can be divided into pushing,pressing,forging,casting and so on.
The standards of large anti-corrosive flange can be divided into national standard(GB),American standard(ANSI),Australian standard(AS),British standard(BS),German standard(DIN),Japanese standard(JIS),Russian standard(GOST),etc.
Cold galvanized slip on flanges finished in Haihao Group
There are the main standards of large anti-corrosive flange:GB/T 9114-2010 pipe flange with neck rebar, GB/T 9115-2010 butt-welded steel pipe flange,GB/T 9116-2010 plain welded steel pipe flange with neck, GB/T 9117-2010 butt-welded steel pipe flange with neck socket, GB/T 9118-2010 butt-welded steel pipe flange with neck.
The large anti-corrosive flanges in chemical industry mainly adopt thermal shrinkage sleeve, which is designed for anti-corrosive welding joints of buried and overhead steel pipes and insulation joint of insulation pipes.It is composed of radiation cross-linked polyolefin substrate and special sealing hot melt adhesive.
