The corrosion is inevitable after exposure to the environment as per thermodynamics even if the metal is stored under good condition. Tyhoo like the other institutions or enterprises is also committed to the research and development of anti-corrosion technology.

TYHOO's pipe insert sleeve is a pipe fitting specially designed to protect the welded joint area of piping from corrosive process fluids by forming a continuous internal coating transmission at the joint welding section.

This equipment is suitable for testing the peeling strength of steel pipe 3LPE/PP external anti-corrosion coating and heat (cold) shrink sleeve (tape) field joint coating, applied to the external coating production line or external field joint coating on site where need perform peeling strength test for coating.
