The surface of the valve should always be kept clean,Keep the lubrication of the valve reduce friction between parts. Not allowed to knock, support heavy objects or stand on the valve, so as not to dirty the valve and damage the valve
Weld Pipe is made of steel plate or steel belt after crimping forming welded steel pipe. Welded steel pipe production technology is simple,high production efficiency, varieties, specifications, less equipment investment, but lower than general strength of seamless steel tube.
: Seamless Pipe has a hollow section and is widely used for conveying fluid pipelines;Seamless Steel pipe for fluid transportation;Seamless steel tubes for high pressure boiler
Non -Destructive testing of macroscopic defects without damaging the object to be inspected;Magnetic Particle testing is performed using ferromagnetic powder coated with a material that fluorescently emits ultraviolet light.
The manual valve is the most widely used valve.The sealing surface strength and the necessary closing force are considered. Valve is in the fluid system, used to control the direction of the fluid, pressure, flow device is to make the pipe and equipment in the medium
Stainless Acid resistant Steel Needle Valve used for Nitric Acid, Acetic Acid, needle valve material should be selected according to its parameters and different temperature the needle valve select is not same.
