UNI Flange manufacturer in India

Supply Series 400, 1300, 1400 UNI Flange for ductile iron pipe

What Is UNI Flanges?
The UNI Flanges helps in eliminating all the issues associated with prefabricated and pre-engineered piping systems. The process of pipe fabrication can be performed on-site without threading, welding, and grooving. They mate with an existing flange and wherein the bolts of the flange are tightened. This leads to the formation of a compression type seal with the mating flange and also the surface of the pipe. The joint basically gets sealed without getting restrained. As the set screws are tightened, they bite into the wall. The UNI Flanges are then locked to the pipe forming a tight connection which restrain thrust. The features of the UNI Flanges are as follows:

  • The fabrication is conducted on-site with the help of a plain ended pipe.
  • It helps in eliminating the issues associated with bolt holes.
  • They permit pipe defection.
  • They come with an end restraint which is built-in.
  • They can be assembled and disassembled easily, hence maintenance becomes easy.

UNI Flange Installation Instructions
The UNI Flange Installation Instructions are as follows:

  • The pipe ends usually need to be cut in a square shape for most of the installation processes. Remove burrs and bevels, if any. Next, the pipe’s plain end should be scraped and cleaned for ensuring a bare metal surface in order to ensure the engagement of the set screw and the gasket seal. It is essential to lubricate the pipe thoroughly, and then the flange can be slid to the pipe easily. Ensure that the cavity of the gasket faces the pipe end. Now, the next step is to slide the lubricated gasket over the end of the pipe. Ensure that the hub faces the joint between the UNI Flange and the pipe.
  • The next step is to slide the flange in the forward direction till the gasket is seated evenly in the cavity of the flanges. The UNI Flange should be flushed with the pipe end.
  • Now the UNI Flange should be bolted with the conventional flanges. It is essential to ensure that the bolts are alternately tightened on the opposite sides. However, the bolts should never be over-tightened.
  • Finally, all the set screws should be advanced to the pipe surface before the torque is applied. The tightening should be done in an alternate manner. A torque wrench can be used so as to verify the proper torque value.

Functions Of UNI Flange
The UNI Flanges helps in eliminating all the issues associated with prefabricated and pre-engineered piping systems. The process of pipe fabrication can be performed on-site without threading, welding, and grooving. All it needs is simple equipment like a plain end pipe, with pipe cutter and a wrench. With UNI flanges, there is no need for off-site fabrications and machine shops. They are widely used for retro-fiiting of piping systems and their renovation.

Where To Use UNI 2282 Pn16 Flanges
Generally, the UNI 2282 Pn16 Flanges are used in industries like natural gas, offshore, shipbuilding, water system, electric power equipment, and many more.

  • Built-In End Restraints
  • Future Maintenance Capabilities

There are two funtions of UNI Flange

1) Seal : When UNI Flange is brought to mate against an existing flange and the bolts are tightened, a copression type seal is created against the mating flanges and pipe surface. The joint is now sealed but not restrained.

2) End Restraint : The hardened set screws 'bite into' the wall of the pipe when they are tightened. The Uni-flange then locked on to the pipe to form a rigid connection providing thrust restraint.
