Slip on flange is a flange that is connected to a container or pipe by fillet weld. It is an arbitrary flange. According to the degree of integrity of the connection between the flange ring and the straight cylinder section, the design is checked by the integral or loose flange respectively. Slip on flange not

When the two edges of the tube blank are heated to the welding temperature, the common metal grains are formed under the extrusion of the extrusion roll, which permeate and crystallize with each other, and finally form a solid weld. If the extrusion force of the weld is too small, the number of common crystals will

Use of heat preservation elbow and hot pressing elbow: Connect two pipes with the same or different nominal diameter to make the pipe bend at a certain angle. Classification of heat preservation elbows and hot pressing elbows: 1. Carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon lapping, ppc, etc. 2.

Now many people will come into contact with the flange, but do not know what kind of flange in the end is what kind of thing, flange appears in people’s lives everywhere, the following to elaborate on the use of carbon steel flanges and connections. Flange connection is the two pipes, fittings or equipment, first fixed in

Flat welded flange is not common in our daily life, but it plays a very important role, for some people who have just started to understand it should not be too much, in this article, to share with you. Flat welding flange can be divided into rotary forging, rotary forging, roll forging, cross wedge rolling, ring

The sealing failure of large flange sealing joint is mainly manifested in leakage. In pipeline systems and installations in various industries, the sealing failure of carbon steel flange joints can cause a large amount of waste of energy and raw materials. If the cost of labor and materials is any more serious, it will lead to equipment

1. Different types of weld: flat welding seam can’t be detected by X-ray, but butt weld can. The welding seam form of flat welding flange with neck is fillet weld, while that of butt welding flange with neck is girth weld; flat welding is two fillet girth welds, and butt welding is one butt girth

Stainless steel butt welding elbow is the general name of all kinds of stainless steel pipe connectors. It has the characteristics of convenient equipment, high performance and easy to use. It has been widely used in the construction and installation of various pipelines. So, how to install stainless steel butt welding elbow? Let’s take a look

Pipe flange and its gasket and fastener are collectively referred to as flange joint. 1. Application Flange connection is widely used in engineering design. It is an essential part of pipeline design, pipe fittings, valves, etc. It is also an important part of equipment components. In addition, industrial furnace, heating, drainage, heating and ventilation, automatic
