puddle flange specification

What factors should be considered when selecting a gi puddle flange for a specific application?

  • Environmental corrosion: It is an important factor in choosing a gi puddle flange for a specific application. The puddle flange must operate in dry and wet conditions and therefore must be made of corrosion-resistant materials.
  • Temperature: The puddle flanges also have to work in extreme temperatures and under sunlight. These should be made up of material that can operate well in high temperatures.
  • Flow pressure: The welded puddle flanges are provided in the pipe to make the pipe connection to other piping systems. It must control the flow pressure or can work in the high-pressure fluid efficiently.

How is an ms puddle flange connected to the main piping system?

  • This type of flange is connected to the main piping system by either doing a welding process, brazing process, or threading process. Before joining the ms puddle flange to the main piping system it is very necessary to clean the surface well.
  • As there must be no residue or smaller particles left as they can be a disturbance in the perfect joining.After the joining process is done give a finishing to the joint surface. After the finishing process lubricate the joints well.

What are the methods used to test the integrity of a stainless steel puddle flange installation?

  • Visual inspection method: This method is done to check any impurities, defects, cracks, or holes are present in the puddle flange or not.
  • Cleanliness: Prior to the installation method, check that the stainless steel puddle flanges are free from any debris or contaminants.
  • Coating: Check that the threaded puddle flange is properly coated with anti-corrosion paint properly.
  • Codes and standards: Make sure that in the making of the flanges, the proper procedures and followed or not as per the industry codes and standards.

What are the requirements for the thickness of the integral puddle flange according to industry standards?

  • These flanges are used to prevent the leakage of water outside the pipe and these pipes pass through walls, floor slabs, concrete structures like tanks, etc. Integral puddle flanges are easy to install and have good strength
  • The integral puddle flange thickness according to the industry standards is in the range of 25mm to 1299mm. These puddle flanges are designed in such a manner that they can be fitted with pipe sizes of 50mm to 100 mm.

What is the maximum allowable pressure for a mechanical puddle flange according to industry standards?

  • The puddle flanges can work effectively in high-pressure conditions. These puddle flanges are used to seal the outside of pipes that are going to pass through the structures made of concrete. These puddle flanges can be installed easily in the walls, floor slabs, and ceiling designs.
  • The maximum allowable pressure for a mechanical puddle flange according to the industry standard is 10 bar water pressure. It can also work superbly in any type of weather conditions. It can also be maintained easily.

What are the typical installation procedures for a carbon steel puddle flange in a piping project?

  • Before installing the carbon steel puddle flange in a piping project make sure that work station is properly cleaned and maintained and all the work areas are released by the contractor.
  • When all these steps that are involved in the installation procedures are completed then again recheck these steps to see whether any discrepancies are left or not for the full satisfaction.
  • Before the process of installation of the square puddle flange, it is necessary to make sure that all the pipe sleeves that are passed through the bricks/walls, and concrete structures are properly inspected.
