ASME B16.5 High Pressure Flanges

High Pressure Flanges
High-pressure flange: A flange used for the connection of pipes or gear with a stress extended than 10MPa. It in most conditions consists of daily high-pressure flanges and high-pressure self-tightening flanges.
Product Overview
Traditional high-pressure flange: It is a place that makes use of the plastic deformation of the sealing gasket (oval gasket, octagonal gasket, lens gasket, etc.) to gain the sealing effect, is linked to the pipe end, and the pipe is linked with each and every and each and every other.
Product Introduction
Traditionally, it consists of a pair of flanges, a spacer, and a extent of bolts and nuts. The gasket is set up on the sealing floor of the two flanges
After tightening the nut, the special pressure on the ground of the gasket reaches a best 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 as soon as extra the sealing reliability is poor.
Features:
1. The sealing principle belongs to plastic deformation
2. Bolt connection
3. The bolt select to go via tensile force, temperature large big difference stress, and many exterior stresses such as bending 2nd and torque
4. The extent is huge, the weight is bulky, and the set up and positioning are very difficult.
5. The sealing conventional regular usual overall performance is unstable, in unique in the harsh case (high temperature, immoderate pressure, and noticeably toxic medium), which is reachable to leak, inflicting serious consequences.
Application characteristics
The high-pressure flange is in the quintessential used in the set up of pipelines, and the high-pressure flange connection is an essential connection mode for pipeline construction, which particularly connects the connection between pipes and performs an crucial 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 equal time with bolts to complete the connection. Some pipe fittings and equipment already have their non-public flanges, which are in addition flange connections. [1] High Pressure Flange Product Performance:
1. Wear resistance: the content material fabric cloth material of Al2O3 in the ceramic layer lined with ceramic composite steel pipe is greater than 95%, and the microhardness is HV1000-1500, so it has instead immoderate put on resistance, and its put on resistance is increased than ten cases massive than that of quenched medium carbon steel, which is improved than tungsten drilling cemented carbide.
2. Corrosion-resistant ceramics are impartial materials, with impenetrable chemical properties, magnificent corrosion resistance and acid resistance, and can face up to a giant vary inorganic acids, herbal acids, herbal solvents, etc., and its corrosion resistance is more than ten situations that of stainless steel.

High-pressure flanges frequently refer to flanges used to be part of pipes and equipment, and their quintessential elements and blessings include:
Withstand immoderate pressure: The high-pressure flange diagram is in a characteristic to stand up to immoderate pressure, making exquisite that the piping laptop computer operates reliably below immoderate stress conditions.
Strong corrosion resistance: high-pressure flanges are normally made of high-strength alloy metallic or stainless steel, which have great corrosion resistance and are incredible for the transportation of corrosive media.
Good sealing: The connection structure layout of the high-pressure flange makes it have right sealing performance, which can effectively end the leakage of the medium and make excessive first-rate the tightly closed 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 effortless to hold and replace.
Wide differ of application: high-pressure flanges are remarkable for high-pressure pipeline constructions in increased than a few industrial fields, such as petrochemical, electric powered powered powered powered power, papermaking, metallurgy and terrific industries.
In general, high-pressure flanges have an imperative role and software program software utility in high-pressure pipeline constructions due to their advantages of immoderate strength, corrosion resistance, proper sealing and reachable installation.
