Gray cast iron casing expansion joints Model SS2 (gray iron) / SSQT (ductile iron), commonly known as expansion joints, expansion joints or pipe compensator First, the scope of the product is suitable for conveying water, fresh water, hot and cold water, drinking water, sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, temperature no higher than 170 degrees of steam and particulate powder and other media. Go buy iron expansion joints Gongyi City Shunxiang water plant! Second, the functional description of gray cast iron casing expansion joints Model SS2 (gray iron) / SSQT (ductile iron), commonly known as expansion joints, expansion joints or pipe compensator. Reference Standard: GB700-8 carbon structural steel, GB2555-81 general purpose pipe flange dimensions, GB9439-88 gray iron castings, GB9876-88 to the sewer with a rubber sealant material, following GB10709-89 110 degree hot water delivery pipe rubber seal material specification. Third, the main function of the cast iron pipe expansion joints mainly due to thermal expansion and contraction produced by temperature changes, effective compensation, especially for PP pipes, steel pipes and other thermal expansion and contraction obvious deformation, expansion joints can play a very good of compensation. To prevent excessive expansion, expansion joints can install anti-pull-off device. Advantages: Compared with steel expansion joints have better resistance to corrosion, suitable for buried underground. Cons: no high pressure resistance, easy installation inadvertently pull rotten.
