Z41W-2205 double-phase steel gate valve Overview the opening and closing part of the gate valve is the gate plate, the direction of motion of the gate plate is perpendicular to the direction of the fluid, the gate valve can only be fully opened and fully closed, not suitable for adjustment and throttling. The two sealing faces of the wedge type gate valve form a wedge, and the wedge Angle varies with the valve parameters, usually 5°.The gate plate of the wedge valve can be made into a whole, which is called the rigid gate plate; It can also be made to produce a micro deformation of the ram, in order to improve its processability, make up for the sealing surface Angle in the processing of the deviation, this ram is called elastic ram. When the gate valve is closed, the sealing surface can be sealed only by relying on the medium pressure, that is, relying on the medium pressure to press the sealing surface of the gate plate to the seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, it is necessary to rely on external forces to force the gate to the seat to ensure the tightness of the sealing surface. The gate valve's gate plate moves in a straight line with the valve stem, which is called the lifting lever gate valve (also called the bright lever gate valve). Usually there is a trapezoidal thread on the lifting rod, and through the nut at the top of the valve and the guide groove on the valve body, the rotating motion is changed into a straight motion, that is, the operating torque is changed into the operating thrust. Some valves, the valve stem nut is located on the gate, the hand wheel rotation drives the valve stem to rotate, and the gate is lifted, this valve is called the rotating rod gate valve or the dark rod gate valve.Z41W-2205 dual-phase steel gate valve tube is defined as stainless steel smelting and manufacturing in its solid quenching structure of ferrite phase and austenitic phase proportion of each half, referred to as 2205 stainless steel pipe, also known as 2205 dual-phase steel pipe. The actual phase proportion is 45~55% ferrite, the corresponding austenite accounted for 55~45%, 2205 duplex stainless steel excellent performance is guaranteed by the appropriate proportion of two-phase structure

2205 duplex stainless steel pipe has excellent mechanical properties and corrosion resistance, as well as good weldability, and has a wide range of applications in the oil and gas industry, Marine engineering, chemical industry and other industries. The length of oil and gas pipelines laid by duplex stainless steel materials in the oil and gas industry has exceeded 850Km, most of which are 2205 duplex stainless steel seamless steel pipes (there are also some S31803 duplex stainless steel pipes and 2507 duplex stainless steel pipes); In the West-east gas transmission project, 2205 duplex stainless steel material is used in high-pressure pipelines due to the strong corrosiveness of the medium transporting natural gas.
