Flange Adaptor Manufacturer
China competitive flange adaptor manufacturer, we have more than 10 types flange adaptor design and we can design according to client requirement.We can offer very competitive price and outstanding quality products based on automatic moulding line.
Flange adaptor, also called flange coupling, it is used to connect flange end of valves, pipe fittings ,meters etc to pipe plain ends.It is important and common ,flange ends is connected rigidly ,socket ends with gasket is flexible connection with pipes which can allow small deflection.To avoid pipe movement, restrained type or mechanical type is also available.
Judberd is a Chinese manufacturer specializing in flange adaptor. Judberd can supply flange adaptor in ductile iron, carbon steel and stainless steel material. The pressure can be PN10, PN16, PN25, PN40, PN63 or PN100, where for PN25 and below, the material of the gland and body of the flange adaptor is ductile iron (ductile iron grade can be ENGJS400-18, ENGJS450-10, EN GJS500-7,ASTM65-45-12 or as per client requirement), for PN40 and above, the material of the gland and body of the flange adaptor is carbon steel or stainless steel (carbon steel or stainless steel can be Q235 ,Q275 or other grade as per client requirement). Judberd’s flange adaptor can be used to connect ductile iron pipes, steel pipes, PVC pipes, AC pipes, GRP pipes etc. For these common pipes, we have dedicated flange adaptor that can be used to connect one type pipe. We also have wide range flange adaptor that can connect several different pipes in order to reduce the stock quantity of distributors. We can also design restrained or mechanical joint flange adaptor for special pipe or service conditions.Below are our flange adaptors,OEM or ODM are welcome.
Why judberd flange adaptor?
Judberd is a flange adapter manufacturer in china with 30 years experience
Judberd can design flange adaptor according to customer’s usage requirements
Judberd has many types of flange adaptor that can be selected by customers
Judberd’s flange adaptor is with flower shape flange, the same flange can be connected to EN1092 PN10 and EN1092 PN16 flange, ANSIB16.48/ANSIB 16.5 and AS4087 flange is also available
We have added a stopper design in the following position, which both increases the sealing surface and improves the sealing performance of the flange adaptor, and the stopper also prevents the pipe from being inserted too deep and thus causing damage to other pipework products such as the valve sealing surface.
The end ring of flange adaptor has a edge ring designed to fix rubber ring, which can ensure that the rubber ring is evenly wrapped around the pipe when it is tight, making it easier to install
There are many types of tie rods to choose from, 4.8 grade, 6.8 grade or 8.8 grade carbon steel, SS304, SS316 and other stainless steel are available.
Rubber can be EPDM, NBR or other materials
The powder on the surface can have multiple colors or different authentication, thus meeting the different needs of customers.

Flange adaptor dimension
judberd can offer below flange adaptors
universal flange adaptor
Size from DN40 to DN700 Pressure is PN10/PN16/PN25
Dedicated flange adaptor
Size from DN40 to DN2500,Pressure is PN10/PN16/PN25 for ductile iron material body and end ring,Pressure is PN10/16/25/40/63/100 for carbon steel or stainless steel material body and end ring
Quick flange adaptor
Size from DN40 to DN400,pressure is PN10/16,for size bigger than DN400,quick flange adaptor will not work
Restrained flange adaptor for PE pipe
Size from OD50 to OD315 ,PN10/16 ,with brass grip ring
Size from OD355 to OD710,PN10/16,with ductile iron Tightening block
Universal step flange adaptor
Size from DN40 to DN2000,Pressure is PN10/PN16/PN25
Mechnical joint step flange adaptor
Size from DN40 to DN2000,Pressure is PN10/PN16/PN25
Mechanical joint vs restrained joint flange adaptor
The restrained joint is a type of mechnical joint designed to prevent the pipe from being pulled out longitudinally. The restrained joint type flange adaptor is designed to prevent the pipe from being pulled out and thus causing leaks.This type of flange adaptor is particularly useful in areas where the ground is unstable or prone to movement, as it prevents the pipe from being pulled out and causing leaks. It is also useful in preventing the tube from being pulled out in the case of HDPE pipes. This type of adapter is easy to install and does not require welding, making it a popular choice for many applications.
Advantage for restrained flange adaptor for hdpe pipe
The restrained flange adaptor has the following advantages over conventional PE pipe hot-melt connections
1. The restrained flange adaptor takes only about 5 minutes to install, compared to 30-40 minutes for hot fusion
2. The restrained flange adaptor requires no special tools or installation experience, whereas the hot fusion connection requires specialist skills and equipment.
3, Restrained flange adaptor is 100% restrained and reliable
4, Restrained flange adaptor saves time and money compared to hot fusion connections.
How to choose the right flange adaptor?
1, You need to make sure that the outer diameter of the pipe is matchable with the socket end of the flange adaptor. If using a wide range flange adaptor, make sure that the range of the flange adaptor includes the outer diameter of the pipe. For dedicated flange adaptor, ensure that the outer diameter of the pipe can be inserted into the socket end of the flange adaptor and that it is well sealed.
2. Make sure that the flange of the flange adaptor is of the same standard, pressure and size as the flange on the pipe, only then can the connection be made.
3, make sure that the length of the flange adaptor is appropriate.
4, To confirm whether the pressure of the flange adaptor meets the pressure requirements of the pipe
What is the different from flange adaptor for hdpe pipe,flange adaptor for pvc pipe and quick flange adaptor for HDPE pipe, quick flange adaptor for PVC pipe?
For PVC and PE pipe,we have same function flange adaptors
one is mechnical flange adaptor with tie rods(for PVC pipe,wide range flange adapor is ok.For HDPE pipe,restrained flange adaptor is needed.),Compare to quick flange adaptor,mechnical flange adaptor with tie rods can offer more stable connection and higher pressure.Both small and big size are available(judberd can offer from DN40 to DN2500),but the Max. size for quick flange adaptor is DN400/OD400,larger than OD400 will not work well.
But quick flange adaptor can be installed more quickly and easier.
