Angle globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters valve VI from below the valve disc, the resistance to be overcome by the operating force is the friction force between the

Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The connection methods with the pipe include: direct welding (commonly used) flange connection, hot-melt connection, electric fusion connection, threaded connection, socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow,

In the production of large Stainless Steel flanges, there are many factors that affect the performance of large flanges. Here are some common factors, First, annealing temperature (the annealing temperature is the temperature parameter when the primer and template are combined. When 50% of the primers and complementary sequences are double stranded DNA molecules, it is

Dual phase steel flange is also called flange plate or flange. Dual phase steel flange is a connecting part between shafts, which is used to connect pipe ends. It can also be used as the flange at the inlet and outlet of the equipment, and is used for the connection between two equipment, such as

Common things for flat welding flanges. The fixing form of the flange and the pipe is applicable to: the flange is sleeved at one end of the pipe, the inner and outer ports of the welding flange, the fixed flange, and the nominal pressure is 2 Below 5MPa.   Butt welding flange, also known as

Flanges, as the name suggests, are used in high pressure environments. Specifically, it is used for connecting flanges of piping and other equipment with pressure higher than 10MPa. There are two main types of high pressure flanges. One is a traditional high-pressure flange, and the other is a high-pressure self tightening flange. Two kinds of

Alloy steel flange connection methods can generally be divided into flat welding, butt welding, socket welding, loose sleeve and thread.   The first four are described in detail below:   1. Flat welding: only weld the outer layer, not the inner layer; It is generally used for medium and low pressure pipelines, and the nominal

There are many materials for international flanges. Now the common materials in the market are forged steel, WCB carbon steel, alloy steel, stainless steel, chromium molybdenum steel, chromium molybdenum vanadium steel, molybdenum titanium, rubber lining and fluorine lining. No matter which kind you need, our company will be useful. However, do not choose companies without

International flange is relatively strict in production. In fact, as long as you bring the word international, you mean the flange produced according to the provisions of relevant standards. Therefore, it is in full compliance with the regulations. Such international flanges will be more assured when used, at least in terms of quality. Since it

International flanges are generally used for connection, so they are often connected with some pipes. But some people don’t know much about its way. In fact, the national standard flange connection is to fix two pipes, pipe fittings or equipment on a flange first, and add flange pads between the two flanges. At this time,
