DESCRIPTION

Butt-welding elbow is a steel hot-pressed or forged elbow, its connection form is directly to the elbow and steel pipe butt welding. Butt-welding elbows can be divided into long-radius butt-welding elbows and short-radius butt-welding elbows according to their curvature radius; there are about 17 kinds of pressure classes, which are the same as American pipe standards, including STD and XS commonly used; 45-degree butt-welding elbows, 90-degree butt-welding elbows and 180-degree butt-welding elbows according to the angle of the elbow. Welding elbow and other elbow with different angles; material is divided into: carbon steel, alloy steel and stainless steel.

Flange butt welding is required for welding flange installation. The general butt welding flange is mostly a neck flange, also called a nipple flange. Butt welding flange is used for the connection of medium and high pressure pipeline, butt welding flange is generally at least pn2.5mpa, butt welding is used to reduce stress concentration.

Compared with butt welded flange, flat welded flange has simple structure and low material consumption, but its rigidity and seal are not as good as butt welded flange with neck. Flat welding flange is widely used in connection of medium low pressure vessels and pipes. Flat welded flanges are suitable for joining carbon steel pipes with nominal pressure not exceeding 2.5mpa. Flat welded flanges can be made into three types: smooth, convex and mortise-groove. Flat welded flanges have a large amount of applications. They are mostly used under mild medium conditions, such as low-pressure non-purified compressed air and low-pressure circulating water. Butt weld flange is a kind of pipe fittings, refers to the flange with neck and pipe transition and pipe butt welding connection. Butt welding flange is not easy to deform, well sealed, widely used, has the corresponding requirements of rigid and elastic and reasonable butt welding thinning transition, weld distance from the joint surface is large, the joint surface is free from welding temperature deformation.
