Product introduction: Vacuum welding gate valve is a kind of mechanical equipment, which is suitable for pipelines with working temperature ≤ 425 ℃ and ≤ 550 ℃ and working medium of water, steam or air.
Overview of NKJ61H vacuum globe valve: The main body of this series of valves adopts casting and forging structure, with parallel double sealing pairs and semi-forced two-way sealing. The sealing surface moves in place and the wedge block moves step by step to achieve zero leakage. The sealing surface has low friction, easy opening and closing, and1
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, mechan1
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
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
The elbow is a kind of pipe fitting used at the turn of the pipeline. Among all the pipe fittings used in the piping system, the proportion is relatively large, about 80%. Generally, different forming processes are selected for elbows of different materials or wall thickness. The commonly used seamless elbow forming processes in manufacturing plant1
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
Tubing is mainly used to connect drill collars and drill bits and transmit drilling power; A casing is a steel pipe used to support the walls of oil and gas wells, ensuring the normal operation of the entire well during the drilling process and after completion.
