SWR Piping Systems with Elastomeric Sealing Ring Joint

Jointing & Installation

• It is imperative to mark the pipe from all sides so that pipe is cut with the help of a Hand Saw. It should be a right angle cut from all the sides. The cut piece should not be with burr on the edges.
• (This step is required when pipe cutting is done from 3 meter pipe to any required length during installation) After cutting, the pipe needs to be chamfered from the outer sides of the pipe. It is advisable to provide approximately 2mm wide, 150 chamfer on pipe end.
• Push the pipe inside the fitting till marked end is completely inserted equally from all sides.

• Do not cut slant/unevenly.
• Do not proceed with installation of pipe without chamfering.
• Do not use a hammer or half push the pipe.

Chamfering

• Remove all the burrs and ridges accumulated on the inner as well as the outer edges of the pipe with the help of a deburring knife, file or abrasive paper.

• Do not proceed with the installation of pipe without deburring.

Deburring and ridge removal

• Thoroughly clean the pipe with dry cloth where the solvent cement is going to be applied to avoid dust, dirt, oil, moisture and other foreign materials during the installation process.

• Do not join the pipes without CLEANING cleaning the pipe ends.

Dryfit Test

• Before applying solvent cement, insert the swr pipe end into the socket of the next pipe or fitting to check that interference occurs at about 1/3rd to 2/3rd of the socket depth.
• Mark the pipe length to be inserted for jointing. Apply a liberal coat of lubricant for easy and smooth insertion.Do not insert the pipe and fitting

• Do not apply solvent cement without conducting Dryfit Test.

Leakage Test

• Leakage tests may be carried out at 0.5 kg/cm2 pressure for 15 minutes. Ensure proper alignment and avoiduse of damaged rubber rings if any.
• Pipe line should be installed in proper alignment and along with necessary clamps.
• Pressure tests may be carried out at 0.5 kg/cm2 pressure for 15 minutes.

• Avoid loose joints & misalignments.
• Pressure testing should not be done before 24 hours of curing.

Cutting

• It is imperative to mark the pipe from all sides so that pipe is cut with the help of a Hand Saw. It should be a right angle cut from all the sides.The cut piece should not be with burr on edges.

• Do not cut slant/unevenly.

Chamfering

• (This step is required when pipe cutting is done from 3mtr pipe to any required length during installation) After cutting, the pipe needs to be chamfered from the outer sides. It is advisable to provide an approximately 2mm wide, 150 chamfer on spigot end.

• Do not proceed with installation of pipe without chamfering.

Deburring and ridge Removal

• Remove all the burrs and ridges accumulated on the inner as well as the outer edges of the pipe with the help of a deburring knife, file or abrasive paper.

• Do not proceed with installation of swr pipe without deburring.

Dryfit Test

• Before applying solvent cement, insert the swr pipe end into the socket of the next pipe or fitting to check that interference occurs at about 1/3rd to 2/3rd of the socket depth.

• Do not apply solvent cement without conducting Dryfit Test.

Cleaning

• Thoroughly clean the pipe with dry cloth where the solvent cement is going to be applied to avoid dust, dirt, oil, moisture and other foreign materials during the installation process.

• Do not join the pipes without cleaning the pipe ends.

Application of Solvent Cement

• Mark the pipe length to be inserted for jointing. Apply a liberal coat of solvent cement with the help of the brush on the marked surface.

• Do not apply excess solvent cement on the swr pipe and do not use solvent cement by hand.

Jointing

• Push the swr pipe inside the fitting/pipe so that it goes inside equally from all the sides. Wipe off excess solvent cement that comes out from all the edges. Hold the joint for one to two minutes so that the jointing is perfect.

• Do not use a hammer or half push the pipe.

Installation & Commissioning

• Pipe line should be installed in proper alignment & along with necessary clamps.
• Pressure testing may be carried out after a curing period of 24 hours.

• Avoid loose joints & misalignment.
• Pressure testing should not be done before 24 hours of curing.
