High neck flangeProducts used in boilers and pressure vessels, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbows, food and other industriesHigh neck flange refers to the high neck height, which improves the stiffness and bearing capacity of the flange.High neck flange: Compared with butt welding flange, the welding workload is large, the electrode consumption is high, and it cannot withstand high temperature and high pressure and repeated bending and temperature fluctuations, but it is more convenient to install on site, and the process of weld film flaw

There are two main systems of international pipe flange standards, namely the European pipe flange system represented by the German DIN (including the former Soviet Union) and the American pipe flange system represented by the American ANSI pipe flange. In addition to this, there are Japanese JIS pipe flanges, but they are generally only used for public works in petrochemical plants and have little international influence. The flanges of various countries are briefly introduced as follows:1. The European system represented by Germany and the former Soviet Union is flanged2.

The formal name of blind disk is Flange cover, and some are also called blind flange or pipe plug. It is a flange without a hole in the middle and is used to seal the pipe opening. The function is the same as that of the head and cap, except that the blind seal is a removable sealing device, and the seal of the head is not ready to be opened again. There are many types of sealing surfaces, including plane, convex, concave and convex surface, tenon and groove surface and ring connection surface.

Threaded flange refers to a flange that is linked to a pipe with the useful resource of thread. When designing, it can be dealt with with free flanges. The attain is that no welding is required and the multiplied torque on the cylinder or pipe is very small when the flange is deformed. The draw decrease lower back is that the flange thickness is massive and the rate is higher.

The butt welding flange is now no longer frequent to deform, seals well, is notably used, has the corresponding inflexible and elastic requirements and good butt welding thinning transition, the welding joint is a prolonged way from the joint surface, and the joint floor is blanketed from welding temperature deformation, it adopts a accelerated intricate cough flare structure, which is great for pipelines with massive fluctuations in stress or temperature or pipelines with excessive te

1. Loose flanges can be divided into three forms: flat welded metal ring free flanges, plate flanging free flanges, and butt welded ring free flanges.2. The free flange is to use flanging, steel rings, etc. to put the flange on the pipe end, and the flange can go on the pipe end. The metal ring or flange is the sealing surface, and the attribute of the flange is to compress them.
