Tubesheet is a kind of round steel, which is used to fix the tube and seal the medium in the heat exchanger. It is a kind of fitting which can weld and fix the pipe. The precision of tubesheet processing, especially the pipe hole spacing and pipe diameter tolerance, perpendicularity and finish, ...

Hot dip galvanizing is an effective way of metal anticorrosion. Flanges hot dip galvanizing refers to the production of flange molding, after rust immersed in the molten zinc at about 500 degrees Celsius, so that the surface of the flange steel member is attached to zinc layer, so as to achieve ...

Once the flange appears rust or the surface of the flange stains, it will cause damage to the flange itself, and may even affect the entire pipeline transport, so that the pipeline leakage. Carbon steel flanges may have cleaning problems after tempering during heat treatment. For example, improp ...

Flange connection consists of a pair of flanges, a gasket and a number of bolts and nuts. Flanges with holes, can wear bolts, so that the two flanges are tightly connected, between the flanges with gasket sealing. The gasket is placed between the sealing surface of two flanges. After the nut is ...

If the problem of flange leakage can not be handled in time, the leakage will expand rapidly under the medium corrosion, form data loss, damage the production environment, make the enterprise stop production, and form huge economic losses. If the accident is the leakage of toxic, flammable and e ...

Spectacle blind flange ASME B16.5 is designed to isolate or connect piping systems.It consists of two discs connected by flat steel, one is  solid and the other hollow ring with the same diameter as the flange.Spectacle blind flange ASME B16.5 is independent of other facilities or equipment in t ...

Stainless steel flange has the ability of corrosion in the medium containing acid, alkali and salt, namely corrosivity; it also has the ability of anti atmospheric oxidation, namely, rust resistance; however, the size of its corrosion ability varies with the chemical composition of the steel its ...

As a sealing and fastening connector, large diameter flange is easy to install, flexible in position and long in service life. It is widely used in large vessels in aerospace, petroleum, chemical and other fields. The welding seam of large diameter flange shall be subject to 100% ultrasonic or r ...

An anchor flange is a device installed on a pipeline to combat axial movement. Resembling a collar, once it is attached to a pipe, the anchor flange is commonly anchored into a concrete foundation. Typically placed onto a section of pipeline as it makes a turn or is at a bridge crossing, the anc ...

Flange is a kind of connection sealing parts. If there are quality problems in the production process, there will be leakage, resulting in economic losses, environmental damage and even safety accidents. So the welding and production of flange is very important. At present, the flange production ...

Flat washers and spring washers are well-known and frequently used washers. Due to the different characteristics of the two,in actual application,the two must be distinguished, otherwise not only cannot play the role of the gasket,but may cause some unnecessary trouble. As the professional flang ...

The tightness of the pressure vessel flange will be affected by the bolt pretension,gasket sealing performance,flange sealing surface characteristics,flange stiffness and operating conditions during use. 1.Bolt pre-tightening force Appropriate pre-tightening force can ensure that the gasket can ...
