Stainless steel flanges have excellent corrosion-resistant performance in water with different qualities, even under the ground, due to thin but solid oxidation film.
Flow characteristics of control valve refers to the relationship between valve opening size and relative flow of medium under the conditions that a valve maintains constant differential pressure.
1. Various performance indicators (mechanical properties, wall thickness, surface): in fact, as a seller, it is good enough to know what is the material and surface of goods.
Stamping elbow, whose full name is stamping welding elbow, is produced through using pressing tool to make the board having the same material with the pipe become a half block of annular elbow and then weld the two half elbow together.
Flat welding flanges save space, reduce weight and have good sealing performance due to no leakage design in joint area.
Two-piece structure is the earliest infrastructure of ceramic valves. During the use, however, we found that this structure is not reasonable, so later we developed three-piece structure and it is often used on double seat valves.
With constant development of the national economy construction, the stainless steel tube is more and more widely used in all kinds of industries.
Stainless pipe cap,is also known as pipe plug or pipe cover. The major function of pipe cap is welded in pipe end to cover the pipe with the same function as pipe plug.
The connection types of butterfly valves can be divided into three kinds: flanged connection, wafer connection and welded connection, which users can select based on specific pipeline requirements.
When rubber seal butterfly valves are used to throttle the flow, improper measures will produce cavitation and make the rubber seat flake or damaged.
