Advantages: Necked flat welding flanges are also classified as flat welding flanges, as they have a short neck, which improves the strength of the flange and improves its load-bearing capacity. So it can be used on higher pressure official roads. Disadvantages: Compared to plate type flat welding flanges, they have a higher cost and are more prone 1
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,1
The fully lined rubber and fluorine lined flange butterfly valve has a simple structure, small volume, and light weight, and is only composed of a few parts. Moreover, the valve can be quickly opened and closed by rotating it 90 °, with simple operation and excellent fluid control characteristics. When the butterfly valve is in the fully open posit1
D63H, D363H, D663H, and D963H PN10~PN100 three eccentric welded hard seal electric butterfly valves use precision J-shaped elastic sealing rings and three eccentric multi-level metal hard sealing structures. They are widely used in industrial pipelines with medium temperatures ≤ 400 ℃, such as metallurgy, power, petrochemical, water supply and drai1
Pressure regulating valve is an actuator product that does not require external energy. Can be used for nominal pressures PN01, PN10. Differential (micro) pressure can be adjusted in stages. From 50mm. W. C to 0.1MPa. It has a wide range of uses and can be used in industrial combustion furnace systems to control the ratio of two materials, such as 1
In pipeline systems, elbows are fittings that change the direction of the pipeline. According to angles, there are three most commonly used types: 45 ° and 90 ° and 180 °. In addition, according to engineering needs, there are also other abnormal angle elbows such as 60 °. The materials of elbows include cast iron, stainless steel, alloy steel, mal1
A concentric reducer is a type of pipe that is directly welded to a steel pipe. The main manufacturing standards for concentric reducers are generally GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/T21635, HG/T21631, and SY/T0510. Corresponding to the concentric reducer, there are also eccentric reducers made of carbon steel, alloy steel, and1
Equal diameter cross, commonly referred to as a professional term, refers to pipe fittings and pipeline connectors, used in main pipelines where branch pipes are required. Equal diameter cross is a type of cross, which can be divided into two types: general equal diameter cross and differential diameter cross. Named because the four ends can be con1
The J61Y and J61H forged steel globe valve series products are not only suitable for medium and low pressure, but also for high pressure. They play a role in cutting off or connecting regulating pipelines in various operating conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries.
