HG High Pressure Flanges

High Pressure Flanges

High-pressure flange: A flange used for the connection of pipes or equipment with a stress expanded than 10MPa. It in most situations consists of everyday high-pressure flanges and high-pressure self-tightening flanges.

Product Overview

Traditional high-pressure flange: It is a location that makes use of the plastic deformation of the sealing gasket (oval gasket, octagonal gasket, lens gasket, etc.) to obtain the sealing effect, is linked to the pipe end, and the pipe is linked with 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 ground of the two flanges

After tightening the nut, the unique strain on the floor of the gasket reaches a nice value, so that the connection is tight and does now no longer leak. This form can be used in flammable, explosive, poisonous media and excessive stress matters to do then once more the sealing reliability is poor.

Features:

1. The sealing precept belongs to plastic deformation

2. Bolt connection

3. The bolt choose to go through tensile force, temperature massive distinction 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 general normal overall performance is unstable, in particular in the harsh case (high temperature, excessive pressure, and notably poisonous medium), which is reachable to leak, inflicting serious consequences.

Application characteristics

The high-pressure flange is in the essential used in the set up of pipelines, and the high-pressure flange connection is an fundamental connection mode for pipeline construction, which especially connects the connection between pipes and performs an imperative function and value. The high-pressure flange connection is to restoration two pipes, pipe fittings or gear on a flange plate first, and between the two flanges, add flange pads, and fasten them at the equal time with bolts to total the connection. Some pipe fittings and tools already have their personal flanges, which are in addition flange connections. [1] High Pressure Flange Product Performance:

1. Wear resistance: the content material fabric fabric of Al2O3 in the ceramic layer lined with ceramic composite metal pipe is higher than 95%, and the microhardness is HV1000-1500, so it has rather excessive put on resistance, and its put on resistance is greater than ten instances large than that of quenched medium carbon steel, which is increased than tungsten drilling cemented carbide.

2. Corrosion-resistant ceramics are independent materials, with secure chemical properties, excellent corrosion resistance and acid resistance, and can face up to a large range inorganic acids, natural acids, natural solvents, etc., and its corrosion resistance is extra than ten instances that of stainless steel.

High-pressure flanges regularly refer to flanges used to be section of pipes and equipment, and their essential factors and advantages include:

Withstand excessive pressure: The high-pressure flange graph is in a function to stand up to excessive pressure, making tremendous that the piping laptop operates reliably underneath excessive stress conditions.

Strong corrosion resistance: high-pressure flanges are usually made of high-strength alloy metal or stainless steel, which have best corrosion resistance and are superb for the transportation of corrosive media.

Good sealing: The connection shape format of the high-pressure flange makes it have correct sealing performance, which can efficiently stop the leakage of the medium and make high quality the tightly closed operation of the pipeline system.

Easy set up and maintenance: The high-pressure flange is bolted, which is reachable and rapid to set up and disassemble, and easy to maintain and replace.

Wide vary of application: high-pressure flanges are splendid for high-pressure pipeline constructions in greater than a few industrial fields, such as petrochemical, electric powered powered powered power, papermaking, metallurgy and remarkable industries.

In general, high-pressure flanges have an vital position and software program application in high-pressure pipeline constructions due to their blessings of excessive strength, corrosion resistance, right sealing and reachable installation.
