What are valve standards?
Many kinds of valves are used in the industrial process, and to ensure proper functionality, compatibility, and safety for end-users, EPC, or engineering, every country has particular organizations to make standards.
The major standard organizations include the American National Standards Institute(ANSI), American Petroleum Institute(API), The American Society of Mechanical Engineers(ASME), British(BS), China valve standards(GB, JB, HG), and so on. THINKTANK provides standard resources for all interesting valves friends study.

Quality Control
A valve can be described as a mechanism that controls the passage of liquids through a pipe. Research states that valves being manufactured in China are amongst the top valve competitors in the valve industry.
Nondestructive Test
Radiography Inspection guarantees no failures inside of the castings or forgings. Ultrasonic inspection acts an alternative of inspection. Dye penetrant testing and magnetic particle testing can examine surface failures on castings and forgings.
Cryogenic Treatment
-196 ℃ Cryogenic Treatment System is a basic treatment for LNG usage valves or similiar applications.
Leakage Test
Leak testing is a procedure that inspectors use to determine whether an object or system is functioning within a specific leak limit.
Chemical Analysis
All our materials are strictly made under supervision of ladle analysis instrument in the foundries and inspected by high precision spectroanalysis instrument when they arrive in our plant.
Mechanical Properties Test
All mechanical properties test will act before we use the materials to secure the performance and safety.
Heat Treatment
Up to 1200 ℃ electric furnance provide an availability of various heat treatment cycles.
