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 oil measuring hole is divided into pedal type and rotary type, which is installed on the top of the oil tank and is one of the main equipment on the top of the oil storage tank. It is mainly used for measuring the elevation of the oil in the tank and sampling. The measuring hole is provided with a closed hole cover and a tightening bolt. In order to prevent sparks caused by impact between the hole cover and the iron when it is closed, the sealing groove of the hole cover is embedded with an oil-resistant rubber pad or soft metal (copper or aluminum).

The ripple compensator belongs to a compensation element.The effective expansion and deformation of the bellows of the working body is used to absorb the size changes caused by thermal expansion and cold contraction of pipelines, conduits and containers, etc., or to compensate the axial, transverse and angular displacements of pipelines, conduits and containers.It can also be used to reduce noise and vibration.It is widely used in modern industry.

Knife gate valve, also known as knife gate valve, knife gate gate valve, slurry valve, and mud valve, has a gate as its opening and closing component. The direction of movement of the gate is perpendicular to the direction of the fluid, and the medium is cut off by a blade shaped gate that can cut fiber materials. The gate has two sealing surfaces, and the most commonly used mode is that the two sealing surfaces of the gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50. The gate of the wedge knife type gate valve can be made into a whole, called a rigid gate. It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate. The valve body actually does not have a cavity, and the gate rises and falls in the side guide groove, and is tightly pressed onto the valve seat by the bottom lug. If high medium sealing is required, an O-ring sealing valve seat can be selected to achieve bidirectional sealing. Knife gate valves have smaller installation space, low working pressure, and are less likely to accumulate debris, resulting in lower prices.

Product Introduction: Product Name and Model: Eccentric Hemispherical Valve Q347 PN16, PN25 Product Usage: Q347F floating soft seal ball valve is used on various pipelines from PN6 to PN40, to cut off or connect the medium in the pipeline, especially for various granular media such as lime powder under harsh working conditions. The selection of bimetallic sealing pairs for different alloys (or combination balls) during overlay welding can be used for working conditions that require wear resistance, corrosion resistance, high temperature resistance, and strict sealing requirements Universal valve: suitable for situations with strict requirements such as sewage treatment, pulp, urban heating and heating, etc Special valves for oil and chemical industry: suitable for various types of oil products such as crude oil and heavy oil, as well as weak corrosion and two-phase mixed flow media in the chemical industry Gas specific valve: suitable for the transportation control of gas, natural gas, and liquefied gas Slurry dedicated valve: suitable for industrial pipeline transportation in liquid and solid two-phase mixed flow or chemical reactions with crystallization or scaling in liquid transportation Special valve for coal powder and ash: suitable for controlling power plants, hydraulic slag removal, or gas conveying pipelines

Product introduction: ZZY type self operated pressure regulating valve does not need additional energy. It uses the self energy of the regulated medium and the power source to introduce the actuator to control the position of the valve core, and changes the pressure difference and flow at both ends to stabilize the pressure in front of (or behind) the valve. It has the advantages of sensitive action, good sealing, low power of pressure set point wave and so on. It is widely used in the automatic control of pressure reduction and pressure stabilization of gas, liquid and steam medium.

All welded ball valves are widely used in city gas, city heating, petrochemical, shipbuilding, steel, pressure regulating station, power plant and other pipeline equipment.

Control the outlet pressure of the main valve, when the inlet pressure level is 1.6 Mpa, the outlet pressure is 1.15-0.8 Mpa; when the inlet pressure decreases, the outlet pressure decreases accoredingly. It can be used in domestic water supply, fire fighting system and industrial water supply system.
