Two way check valve
The types of oxygen shut-off valves and flange shut-off valves are divided into external threaded and internal threaded pneumatic shut-off valves based on the position of the valve stem threads. According to the flow direction of the medium, there are direct flow, direct flow, and angular flow. Globe valves are divided into packing sealed globe val1

Tee carbon steel pipe fittings
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

Flat welding flange with neck
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

180 ° welded elbow
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

Concentric reducer
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
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
