Product overview
In the chemical production industry, it is often necessary to add gas or materials directly to the liquid level of the reactor, but there is agitation in the reactor, ordinary steel pipes are faced with corrosion, fracture and other factors. Therefore, double-layer steel pipes or thick-walled pipes are used to ensure strength. Both inside and outside the steel pipes are used to wrap the steel pipes in contact with materials to protect the steel pipes from corrosion by chemical substances. When there is no stirring in the equipment, it can be made of ordinary thin-walled steel pipe, which is more economical and practical.
