Stainless steel pipe is a kind of hollow long cylindrical steel. Its application scope is used as the pipeline for conveying fluid, mainly used in petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and other industrial transmission pipelines and mechanical structural components. The stainless steel pipe is made of the billets of acid

There are two systems in the international pipe flange standards, namely the European pipe flange system represented by DIN (including the former Soviet Union) and the American pipe flange system represented by ANSI. In addition, there are JIS pipe flanges in Japan, but they are generally only used for public works in petrochemical plants, and

How to determine the flange size? 1.First, judge the flange type. Common flange types include flat welding flange,Butt Welded Fitting, SOCKET WELD/SW FLANGE, plate welding flange and ring loose flange. 2.Second, judge the flange end form, mainly RF, concave, convex, RJ torus. Tenon groove face 3.After judging the flange type, the main measured data are

LAP JOINT/LJ FLANGE is also called flange. It’s a part of the tube that connects with the tube. Connect to pipe end. There are holes on the flange, and bolts can be worn to make the two flanges tightly connected. The flange is sealed with gasket. Flange pipe fittings refers to the fittings with flange

1. In order to prevent eye to eye corrosion due to heating of flange cover, the welding current should not be too large, about 20% less than that of carbon steel electrode, the arc should not be too long, the interlayer should be cooled quickly, and the narrow weld bead is preferred. 2. The welding

A valve device for a Sanitary Fitting having at least two control elements which are movable relative to one another and on which at least two inlet channels and at least one control channel are formed is described. The control channel is configured for a communicating connection between at least one of the inlet channels

Flange connection is to fix two pipes, fittings or equipment on a flange separately, between the two flanges, plus flange pad, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection. Flange connection is an important connection mode in pipeline

National Day is approaching. This year marks the 70th anniversary of the founding of New China. Many friends have already planned where to travel. They are very excited, but safety comes first. Therefore, we must pay attention to travel safety. Next, I will share some precautions for traveling safety during the eleventh long vacation. 1.Before

Carbon steel flanges are generally adaptable and can be used in different fields, and the carbon steel flange produced by this method is pn≥2 to the pressure of oil and gas field. 5MPa long distance transmission pipeline, station yard and other insulating carbon steel flanges are used. Simply change the carbon steel flange to the

The weld form is different: the weld seam cannot be radiographic inspection, and the weld seam can be welded. The welded weld seam with slip on flange pipe and flange is a fillet weld, and the welding weld seam with neck weld neck flange and pipe is ring weld; the flat weld is a two-fillet weld, Butt-weld.
