A three-way fitting is a type of pipeline connector used at the branch of the main pipeline, which can be divided into equal diameter and reduced diameter. Tee fittings are used in areas where pipelines have branches, and due to their convenience and simplicity, they are widely used in fields such as chemical engineering, civil construction, mechanical manufacturing, and shipbuilding. A tee is a type of pipe fitting used at the branch of a pipeline. For the manufacturing of tees using seamless pipes, there are usually two processes used: hydraulic bulging and hot pressing forming.

Bend pipes are bent using a complete set of bending molds, which are divided into two processes: cold bending and hot pushing. Regardless of the type of machine equipment and pipeline, most of them use bent pipes, mainly for oil, gas, infusion, and other purposes. Classification: According to the production method, it can be divided into pushing, pressing, forging, casting, etc. According to manufacturing standards, it can be divided into national standards, electrical standards, ship standards, chemical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc. According to its curvature radius, it can be divided into long radius elbows and short radius elbows. A long radius elbow refers to a pipe with a curvature radius equal to 1.5 times the outer diameter, i.e. R=1.5D; A short radius elbow refers to a curvature radius equal to the outer diameter of the pipe, i.e. R=1.0D. (D is the diameter of the elbow, R is the radius of curvature). If divided by pressure level: there are about seventeen types, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; The most commonly used ones are STD and XS.

The tank top vent pipe is installed on the top of the heavy oil tank to breathe and provide sufficient ventilation conditions for the tank. At the same time, it plays an overflow protection role in the accident state to ensure the integrity of the tank and ensure the fire safety of the oil product reservoir area, which is generally connected by flange.

Competitive Advantage: 1. 18 Months Guarantee for quality. 2.OEM manufacturer, print client’s LOGO on the valve body. 3.Offer Operation Manual & Install Introduction for safety use. 4.Offer manufacturer’s reasonable price to win the market for both. 5.Accept any the third party inspection. 6.As a factory, every production process can be controlled during manufacture. 7.Offer inspection & testing reports for raw materials, production process, wall thickness, face to face dimension, pressure test, welding test, painting test, etc.

Product introduction: Piston type steam pressure reducing valve is to control the opening of the opening and closing parts in the valve body to adjust the flow of the medium and reduce the pressure of the medium. At the same time, it can adjust the opening of the opening and closing parts with the help of the pressure behind the valve to keep the pressure behind the valve within a certain range. In the case of constant change of the inlet pressure, it can keep the outlet pressure within the set range and protect the subsequent life and production appliances.

Overview of ZX pneumatic diaphragm three way control valve: ZX new series pneumatic diaphragm three-way control valve adopts cylindrical thin-wall window valve core guide,which is different from the bushing guide of plunger valve core.Equipped with multi spring actuator.ZX type pneumatic diaphragm control valve has the advantages of simple structure,light weight,small volume and convenient disassembly.Widely used in accurate control of gas,liquid and other media,process parameters such as pressure,flow,temperature,liquid level to maintain a given value.The utility model is suitable for the occasions where one fluid flows out in two paths through the three-way valve or two fluids are combined into one fluid through the three-way valve. This series of products have two kinds of three-way confluence (ZXQ) and three-way shunt (ZXX). The nominal pressure rating is 1.6, 4.0 and 6.4Mpa, and the diameter range of valve body is DN25-200. The applicable fluid temperature ranges from - 60℃ to + 450℃.The leakage standard is grade IV.There are two kinds of flow characteristics:straight line and parabola.
