PIPE SLEEVE

Reli Sleeve™ can be manufactured for OD & N.B. sizes starting from 2” to 72”.

• Girth Weld Safety-Detach 1-2 from the Burn-back welding channel, securing the steel substratum.
• Natural accommodation-Container-appropriate handling of the corrosive environment.
• Improving the top and tapered ends of flow-smooth contributes to increased flow and decreased turbulence.
• Secure anchor- If the recessed metal backing ring of the mounting is attached to the two ends of the pipe with tabs or pins during the welding process, the mounting is tightly secured to the shaft.
• They can use any solvent and powder for decoration.

Pipe Sleeve are found in many various industries and applications. Below are only a few of them listed.

• Applicable in onshore, marine, industrial, and petroleum pipelines.
• Holds an I.D. Coating from the spattering of harmful welds during construction.
• Suitable for all types and degrees of tubing in API 5L, ASME, ASTM material such as carbon fiber, and stainless steel.
• No specially trained welder needed is mounted using a standard welding technique.
• Isolates the portion of welded girth with a 100 percent I.D. Loop screwed shut.
• It is part of the finished tube at completion, having the same permanent corrosion protection as the carrier tubing.

Pipe sleeve are coated with liquid or powder coatings 100 percent internally & externally. Based on the substance which flows through the tube, the sleeves may be painted. Several of the most commonly used coatings for pipeline coverings are:-

RECOMMENDED INSTALLATION PROCEDURE FOR PIPE SLEEVE

• The checking state of the tubing continues to ensure no harm happens. Wash the earth, garbage, and other plant-influencing waste. The heat pipe stops to extract water or moisture at temperature 60-80 ° C if any is found. Measure the shaft’s inner diameter, to be at least horizontally and vertically within tolerance.
• The Pipe Sleeve coating does not cause any harm, corrosion or other negative defects. Ensure the sealing pins, heat-resistance tape and other accessories are of high quality.
• Mix epoxy mastic according to the mixing ratio and hold returning to the life of the epoxy pot when combined as suggested by a supplier.
• Both welding operations must be downwards of 7 to 10 inches (175 to 250 mm) per minute. To allow the exhaust of expanding gases, a weeping hole of 0.5″ to 1″ (12.7 to 25.4 mm) is left. When passing the welding tab a weaving motion of the electrode must be produced to ensure complete melting.
• Do not initiate intermediate passes until the weld has cooled down to or below 120 ° C. The weep hole will be filled at the start of the first filler run. Wait for as many passes as possible to complete the weld, and keep the weld downhill. The slags and other welding materials shall be removed from both passes.
• Push the sleeve to one end of the thread, until the shaft’s bevel edge meets the pins. The process of injection shall be systematically shifted horizontally by hand. Add the next primed pipe end to the correct sleeve with epoxy, until the pins touch the bevel edge of the plug.
• For welding procedures adhere to standard API 1104 or SAE31.1 chapter 9. Choose the lowest power rates available to hold the machines. The welded frame must be well ventilated and can be secured against inclement weather. During the welding process, pipe coatings and epoxy can emit toxic gasses. Connects the part MSDS to the welding cycle.
• If preheating is required, after application of epoxy mastic heating from the outer pipe may not exceed 120 ° C. Attached manually to each end of the pipe but never to sleeve tabs and never welded or fastened to the center of the tubing. An additional pipe lock may be used for the purposes of welding tabs to connect the securing ends. Reli Sleeve avails it’s products all across India and various countries abroad as well.
