Pipe Sleeve / Insert Sleeve for Internally Coated Steel Pipe

RELI SLEEVE, is a part of Reliable Group of Companies manufactures Insert sleeve also known as pipe sleeve in sizes from 2” to 72”. Reliable markets its product with the trademark name RELI-SLEEVE. RELI-SLEEVE specializes in manufacturing custom made pipe sleeve/insert sleeve which can be used in place of reducers to join to different diameter pipes.

The Reli-Sleeve is designed to protect the girth weld area from corrosion & also to provide 100% internally coated pipeline. Internally coated steel pipes suffer a major drawback of corrosion at the girth weld area. Until recent years internal coated pipelines were not much in use due to the uncoated portion of the girth-weld area. The insert sleeve offers a homogeneous coating internally and also protects the girth weld area from corrosion.

The insert sleeve/pipe sleeve have a major advantage due to its easy-fabrication and fast assembly. There are many alternative solutions available in the market to protect the girth weld area from corrosion but are very expensive and require complex robotics technology. Protecting the girth-weld area from corrosion through such complex robotics is not only very expensive but also time consuming. The complexity of the job is also limited to larger sizes. Insert sleeve/ pipe sleeve are the only resource for fast assembly & cheaper solution for protecting the girth-weld from corrosion in stainless steel, carbon steel & other steel pipes also they possess an advantage of their size range which is suitable for sizes up to 2 inch also. Pipe sleeve/ insert sleeve do not require any special equipment for installation and are a cheaper resource as transportation of the sleeve is an easy process.

PROBLEM SOLVER
During the welding process, heat generated within the pipe will burn back the internal plastic coating approximately 1-2 inches from the welding seam. This sleeves and fittings are designed to isolate the burn-back of the coating and protect the steel substrate.

Advantages

• 1. Pipe Sleeves / Insert Sleeves can be manufactured in both stainless steel & carbon steel in any grade as per customer requirement.
  2. Applicable to a wide variety of pipeline systems both onshore as well as offshore pipeline systems.
  3. Pipe Sleeves / Insert Sleeves can be custom fabricated as per the line pipe.
  4. The field joint can be X-Rayed 100%.
  5. Pipe Sleeves / Insert Sleeves can be coated with any liquid or powder coatings.
  6. Pipe Sleeves / Insert Sleeves are custom fabricated to cover the cut-back portion of the internal coated pipe.
  7. Pipe Sleeves / Insert Sleeves have an advantage of easy manufacturing & can be manufactured along with the pipeline where it has to be installed which saves a lot of time as compared to complex robotics technology where the work can proceed only after the welding process of the pipe is complete.
  8. Pipe Sleeves / Insert Sleeves does not require any special equipment’s or training.
  9. Mastic forms a smooth surface at the sleeve edge & form a insulation barrier to obstruct flow of the pipeline material between the pipe & sleeve.

Coating

The internal coated pipelines increase the life span of the pipeline by saving the pipeline from corrosion. Pipe Sleeves / Insert Sleeves are coated with the same material as the pipe and the coating is applied with the same technology as the pipe coating (including high temperature baking) the whole pipeline is fitted with a uniform coating film of the same high quality and performance. Any other coating applied at the welding seam area after pipe welding which is cured at ambient temperature creates a pipeline with serious problematic zones.
Hence the pipe sleeve/ insert sleeve has to be coated with the same coating as the pipeline. Some of the most common coatings used are listed below depending upon the following factors:-

• 1. The fluid or gas passing through the pipeline.
  2. Minimum & maximum operating temperature.
  3. Velocity of the material flowing through the pipeline.
  4. Minimum & maximum Operating pressure.

The coatings that are generally used to coat pipe sleeve/ insert sleeve are as below:

Pipe Sleeve / Insert Sleeve used for :

Insert Sleeve / Pipe Sleeve for Internally Coated Steel Pipes
The Sleeve is inserted into the end of an internally coated pipeline. A second internally coated pipe is then slipped over the protruding half of the Sleeve so that both ends of the pipes touch the weld nubs. The fitting weld numbs ensure proper spacing for the final welding process.
The Sleeve installation is completed with a simple welding procedure that will provide a 100% internally coated pipe. The Sleeve is the most simplistic and efficient method to provide full corrosion protection for all internally coated pipeline systems
Stainless Steel Pipe Sleeve / Insert Sleeve for Prevention of Stress Corrosion Cracking
The Pipe/Insert Sleeve and weld band can be manufactured from stainless steel tubing using the same materials as the destination pipeline. Using the same pipeline materials eliminates the traditional problems caused by welding dissimilar metals. Additionally, the Stainless Steel Sleeve reduces potential stress corrosion cracking in the weld area.
Standard weld procedures for the specific grade of stainless steel pipeline may be used to weld the Stainless Steel Sleeve into place. Specific o-rings are selected to provide the best long-term performance for the individual pipeline application.
Pipe Sleeve / Insert Sleeve for Cement & Mortar Line Pipes
The Sleeve can be manufactured to provide weld area protection for cement and mortar lined pipelines. The Sleeve is manufactured to the same thickness of the pipe lining. The result is a pipeline that does not have an I.D. restriction and has eliminated the traditional damage and loss of material durability caused by extreme heat introduced by a hydraulic set.
The cement sleeve offers the same weld area protection as the standard pipe / insert sleeve installed in thin film coating pipelines. The cement Sleeve uses a multiple system and removable spacer nubs to ensure proper weld area spacing.
Unlike the tapered ends of the standard CC Sleeve, the cement sleeve designed for mortar lined pipes is squared on the ends. The pipeline mortar is blanked off two inches from the end of the pipleine.
Purpose and Application
Bush “oil” – a product intended for corrosion protection of internal weld. Bush “oil” is used when connecting pipes (fittings) with an internal anti-corrosion coating in transporting oil and gas mixture, water harvesting and other harsh environment applications
