Plate slip on flange (chemical standard HG20592, national standards gb/t9119, Machinery jb/t81): Easy to draw, simple to manufacture, low cost, wide use, but the rigidity is not good, so it can not be used for supply and demand, flammable, explosive and higher vacuum requirements of the chemical process piping system and high, extremely hazardous occasions. The

Stainless steel slip on flange is convenient, simple to manufacture, low in cost and widely used, but the rigidity is poor, so it can not be used in the chemical process piping system with the requirement of supply and demand, flammable, explosive and high vacuum degree, and high and extreme harm. The sealing type has

Manufacturing high-pressure elbow pipe material needs some special raw materials for production, these raw materials to be tough choice and control, raw materials to choose the right, otherwise the production of high-pressure elbow will not have quality assurance. High-pressure elbow bend Pipe Application Data is a large class of special electricity, the new data of

1. Hot-Push forming Hot-push elbow forming process is the use of special elbow push machine, core mold and heating device, so that the billet on the die in the push machine pushing forward movement, in the movement by heating, expanding and bending forming process. The deformation characteristic of the hot-push elbow is to determine the

High-pressure pipe fittings are used in specific environment such as high-pressure steam equipment, chemical high-temperature high-pressure pipelines, power plants and nuclear power plant pressure vessels, high-pressure boiler accessories. Pipe fittings are the general designation of parts that connect, control, change direction, shunt, seal and support in piping system. Pipe Use classification 1. Pipe fittings For

The quality of different-diameter tube high-pressure pipe fittings should conform to the current national standard “steel butt welded Seamless pipe” GB/t 12459-2005, the roundness of the reducer should not be greater than the corresponding end diameter of 1%, and allow the deviation of the ±3mm; the permissible deviation of the size of the reducer shall

Flange is a disk-like part, in the pipeline engineering is the most common, flanges are used in pairs. In piping engineering, flanges are mainly used for connection of steel pipes. In the need to connect the pipeline, a variety of installation flange, low pressure pipe can use wire flange, more than 4 kilograms of pressure

Langfang Ding Yang flange pipe fitting Co., Ltd specializes in producing insulating flanges and stainless steel carbon steel pipe. Tee pipe fittings are usually used in construction, power, shipbuilding, chemical and other industries. Different types of tee fittings have their own shortcomings and advantages. Different types of three-way pipe fittings have different characteristics, to distinguish between

Now the common standard of carbon steel flange is generally divided into: sy/t5037-2000 (Ministry of Standard, also known as ordinary fluid pipeline with spiral seam submerged arc welded steel pipe), gb/t9711.1-1997 (GB, also known as the oil and gas industry transportation pipe Delivery Technical conditions Part I: A-class steel pipe (to the current requirements of

Flange is a disk-like parts, in the pipeline engineering is the most common, flanges are used in the pipeline engineering, stainless steel flange is mainly used for the connection of steel pipe. In the need to connect the pipeline to install a flange, low pressure pipe can use wire flange, more than 4 kilograms of
