Type B Sleeve Leading Manufacturers & Exporters

Reli Sleeve offers a number of solutions for pipeline repair. One such possibility is the type B sleeve. Repairs can be conducted without shutting down the pipeline with the type B sleeve.

When a pipeline operator discovers an abnormality that threatens to shut down their pipeline, they repair it using approaches that return the system to its original design structure before the incident. In such a circumstance, Reli Sleeve can help by providing Type B sleeves, which can be used to regulate leaks or reinforce an area where there is a fault. The Type B Sleeve is similar to the Type A Sleeve, except that it is fully welded to the pipe.

Type B Sleeves come in a variety of diameters, wall thicknesses, and grades of steel plates, all of which are ASTM certified and have a longitudinal edge. Type B sleeves come in a variety of grades and varieties, and can be customised to meet the needs of the customer.

Customers like the Type B Sleeve because it may be put on a pipeline without welding it into the former carrying pipe. Because the Type B sleeve is unable to hold pressure, it should only be used for non-leaking flaws. The Type B sleeves should be used in low-pressure situations where the fault is likely to fail.

PROPERTIES OF TYPE B SLEEVE

One of the major advantages for the users of the Type B sleeves as compared to the other sleeves is that for relatively smaller flaws it can function extremely effectively without having high structural integrity. Hence, we can claim with pride that we provide sturdy, best quality Type B Sleeves pipes for multiple uses.

PRINCIPAL OPERATION OF TYPE B SLEEVE

The early work by Battelle showed that steel sleeves are effective because they restrain bulging, or accumulation of strain, in the defective area while absorbing only 15 to 20 per cent of the hoop stress in the carrier pipe. Steel sleeves are effective because the stiffness (elastic modulus) of the sleeve material is equivalent to that of the line pipe steel.

MATERIALS USED FOR TYPE B SLEEVE

ASTM specifications are followed to manufacture Type B sleeves from superior quality carbon steel plates. Structural quality carbon steel or pressure vessel quality carbon steel is used according to the usage and requirement of the client.In addition to these, the Type B sleeves can also be made in any custom grade as per the client usage.

PRODUCTION OF TYPE B SLEEVE

After immense research and experience, we can claim with pride that we provide sturdy, high-quality Type B sleeves pipes for multiple uses. Reli Sleeve is one of the best producers of the Type B sleeves. The production process of Type B Sleeves is elaborately done from the latest technology and highest industry standard machinery. Our production team is an experienced one with over a decade of knowledge of the field.

ADVANTAGES & DISADVANTAGES OF TYPE B SLEEVE

One of the claimed advantages of composite repairs over steel sleeves is that their installation requires no welding to an in-service pipeline. It is clear from the discussion above that the installation of Type B sleeves, which can serve the same purpose as composite repairs, also requires no welding to an in-service pipeline. Welds that do not contact the carrier pipe are not considered to be “÷in-service’ welds according to Appendix B of API 1104, even though longitudinal seam welds are made while the pipeline is in-service.

Another claimed advantage of composite repairs is that their installation is simpler than steel sleeves. While this may be the case for Type B sleeves where welding to an in-service pipeline using specially qualified welding procedures and specially qualified welders is required, this is certainly not the case for Type B sleeves. Type B sleeves require no in-service welding, can have fillet-welded overlapping side strips (see Figure 4), and are very simple to fabricate and install. They can be supplied with the side strips fillet welded to the bottom half of the sleeve so that the only welds required in the field are the fillet welds on the top of the side strips. These welds can be readily made by welders without special training or qualification. The raw materials required to make Type B sleeves are significantly less expensive than composite materials. Type B sleeves can be fabricated in the field by simply splitting a length of pipe of equal, diameter, wall thickness and grade as the line-pipe material. Unlike composite materials, steel sleeves have no finite “÷shelf life’. Also, the stiffness and long-term performance of Type A sleeves are equivalent to that of line-pipe steel.

While the long-term performance of steel is well established, the long term performance of composite materials on buried pipelines beyond about 20 to 25years has not yet been demonstrated. The significantly reduced stiffness of composite materials compared to steel makes the use of composite repairs questionable for application to pipelines that experience cyclic pressure fluctuations. Cyclic strains in the defect area may cause the defect to grow and eventually fail in subsequent service.

Both Type B sleeves and composite sleeves rely upon the use of an effective sealer to keep potentially corrosive fluids (e.g. groundwater) from entering the crevice area between the carrier pipe and the repair. Corrosion under Type B sleeves can be prevented by using either an elastomeric sealant or a hardenable sealant.

While Type B sleeves do have to be fillet welded to the pipeline (see Figure5), they can be used where composite repairs cannot, such as for repair of defects that are 80 per cent deep or greater, circumferentially-oriented defects, leaking defects or for defects that will eventually leak (e.g. internal corrosion), and cracks. The raw materials required to make Type B sleeves are significantly less expensive than composite materials and the stiffness and long-term performance of Type B sleeves are equivalent to that of line-pipe steel.

When considering the cost of various repair options, both material cost and cost of installation need to be considered. Mobilisation cost and the application cost of steel sleeves may be highly variable, depending upon availability and labour rates for welding personnel. While the mobilisation cost for composite repair installation may be less in some cases, the materials are more expensive. Composite sleeves or wet layup composite repair kits are typically designed for a standard, fixed length. If the length of the area requiring repair is longer than that which can be repaired by a single composite sleeve, the use of steel sleeves may be significantly less expensive than composite repairs.
