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,

Polishing method of dual phase steel flange 1. There are four polishing methods of dual phase steel flange: manual, mechanical, chemical and electrochemical. Polishing can improve the corrosion resistance and decoration of the flange. The existing electrolytic polishing solution for stainless steel still uses phosphoric acid and chromic anhydride. During polishing and cleaning, some chromium

The existence of dual phase steel flange restricts the growth of grains between dual phases. Dual phase stainless steel maintains fine grains, and the total area of grain boundary of dual phase stainless steel is larger than that of single-phase steel. Therefore, dual phase stainless steel has high strength, especially yield strength, ensuring certain plasticity

I. paint maintenance solutions Maintenance paint is a hard film that can be directly bonded to the substrate, generally epoxy or polyurethane coatings. There are many edges and edges in the China flange, and the edge will become thinner with the service time and the action of corrosive medium. It is difficult for the conventional coating
