Steel Flanges EN1092/ISO7005

Product Description

Steel Flanges is a product in pipe fittings, specially designed to be used with pipes. It is a fitting product with holes, two flanges are connected by bolts, and gaskets are used between the flanges for sealing. This connection method has good pressure resistance and corrosion resistance, as well as excellent sealing performance.

Backing rings

Puhui provides state-of-the-art fitting accessories
for jointing HDPE piping system which not only
ensures the safe conveyance but also makes it
possible to easily move HDPE pipes at a later stage.
Flanged Joints (with Stub Flanges and Backing Plates) – HDPE pipes can be flange-jointed by using HDPE stub
Hot-dip galvanized flange is a class of flanges with good corrosion resistance, can be made in the flange after the formation of rust immersed in about 500 ℃ melting zinc liquid, so that the surface of the steel components attached to the zinc layer, so as to play the purpose of anti-corrosion.
flange ends in conjunction with metal backing plates and a sealing gasket to provide a demountable joint or to
match up with pumps, valves etc.
Backing Rings have been modified as per the requirements of HDPE sizes.
Puhui can provide variety of backing ring for mechanical connectios in galvanized steel, statinless steel and PP coated steel.

Role of Steel Flanges

Steel Flanges play a vital role in the pipeline system, and its role is reflected in the following aspects:

1. Connecting pipes: It can connect two pipes in the same system to ensure that the fluid can flow smoothly, so as to achieve connection and disconnection between pipes, and facilitate maintenance and replacement.

2. Connecting equipment: In addition to connecting pipes, it can also connect various equipment, such as water pumps, compressors, storage tanks and conveyor belts, to ensure that fluids or materials can flow freely from or into the equipment.

3. Adjust the flow or pressure of the pipeline: By installing flanges of different sizes, the flow or pressure of the pipeline can be changed to achieve control of fluid flow. ‌

4. Easy installation and disassembly: The design of Steel Flanges allows for easy installation or disassembly, thus simplifying the process of pipeline maintenance or equipment replacement. ‌

5. Leakage-proof: By tightening the bolts, the pipeline can be kept sealed to prevent fluid or gas leakage. ‌

6. Corrosion resistance: With excellent corrosion resistance, it can be used in humid and acidic environments to ensure the durability of the pipeline system. ‌

7. Safety guarantee: In compliance with international standards, the use of qualified Steel Flanges can effectively avoid safety accidents such as leakage and explosion in the pipeline system due to fitting problems, ensuring the safety of the pipeline system.
