JB High Pressure Flanges

High Pressure Flanges
High-pressure flange: A flange used for the connection of pipes or tools with a stress increased than 10MPa. It in most instances consists of normal high-pressure flanges and high-pressure self-tightening flanges.
Product Overview
Traditional high-pressure flange: It is a area that makes use of the plastic deformation of the sealing gasket (oval gasket, octagonal gasket, lens gasket, etc.) to attain the sealing effect, is linked to the pipe end, and the pipe is linked with each and every other.
Product Introduction
Traditionally, it consists of a pair of flanges, a spacer, and a volume of bolts and nuts. The gasket is set up on the sealing flooring of the two flanges
After tightening the nut, the specific pressure on the ground of the gasket reaches a positive value, so that the connection is tight and does now no longer leak. This shape can be used in flammable, explosive, toxic media and immoderate stress things to do then again the sealing reliability is poor.
Features:
1. The sealing principle belongs to plastic deformation
2. Bolt connection
3. The bolt want to suffer tensile force, temperature big difference stress, and many exterior stresses such as bending 2d and torque
4. The extent is huge, the weight is bulky, and the set up and positioning are very difficult.
5. The sealing standard overall performance is unstable, specially in the harsh case (high temperature, immoderate pressure, and exceptionally toxic medium), which is handy to leak, inflicting serious consequences.
Application characteristics
The high-pressure flange is in the important used in the set up of pipelines, and the high-pressure flange connection is an necessary connection mode for pipeline construction, which particularly connects the connection between pipes and performs an indispensable feature and value. The high-pressure flange connection is to restoration two pipes, pipe fittings or equipment on a flange plate first, and between the two flanges, add flange pads, and fasten them at the same time with bolts to whole the connection. Some pipe fittings and equipment already have their private flanges, which are moreover flange connections. [1] High Pressure Flange Product Performance:
1. Wear resistance: the content material cloth of Al2O3 in the ceramic layer lined with ceramic composite metallic pipe is greater than 95%, and the microhardness is HV1000-1500, so it has exceedingly immoderate put on resistance, and its put on resistance is higher than ten cases larger than that of quenched medium carbon steel, which is greater than tungsten drilling cemented carbide.
2. Corrosion-resistant ceramics are unbiased materials, with impervious chemical properties, remarkable corrosion resistance and acid resistance, and can face up to a wide variety inorganic acids, herbal acids, herbal solvents, etc., and its corrosion resistance is more than ten cases that of stainless steel.

High-pressure flanges commonly refer to flanges used to be part of pipes and equipment, and their indispensable elements and benefits include:
Withstand immoderate pressure: The high-pressure flange design is in a role to stand up to immoderate pressure, making positive that the piping machine operates reliably under immoderate stress conditions.
Strong corrosion resistance: high-pressure flanges are normally made of high-strength alloy steel or stainless steel, which have perfect corrosion resistance and are terrific for the transportation of corrosive media.
Good sealing: The connection form layout of the high-pressure flange makes it have good sealing performance, which can effectively end the leakage of the medium and make positive the impervious operation of the pipeline system.
Easy set up and maintenance: The high-pressure flange is bolted, which is reachable and speedy to set up and disassemble, and simple to keep and replace.
Wide range of application: high-pressure flanges are excellent for high-pressure pipeline constructions in extra than a few industrial fields, such as petrochemical, electric powered powered power, papermaking, metallurgy and extraordinary industries.
In general, high-pressure flanges have an imperative role and software program in high-pressure pipeline buildings due to their advantages of immoderate strength, corrosion resistance, correct sealing and reachable installation.
