Full Encirclement Steel Sleeve / Full Reinforcement Sleeve / Half Pipe Soles / Half Pipe Wrap / Split Sleeve
Type A Sleeve | Type B Sleeve
Mettalo Piping Products Inc., Manufacture a Complete Line of Full Encirclement Steel Sleeve This Sleeves are probably the most important and widely used method of General Repair of Pipeline Defects.
Full Encirclement Steel Sleeves consist of a Cylindrical Shell Placed around the pipe section to be Repaired and Welded along the Two Longitudinal seams. There are Two Types of Sleeves, herein referred to as “Type A” and “Type B.” Sleeves can be made from Pipe or Rolled Plate Material.
It was a Result of the work that began in the year 1970 show that a properly fabricated steel sleeve restores the strength of a defective pipeline segment to at least 100% of the specified minimum yield strength (SMYS). Damaged pipe sections repaired using properly installed repair sleeves failed in the pipe body away from the repair.
To prevent an area of corrosion or other damage from causing a Pipeline to Rupture, the area containing the damage must be reinforced to prevent the pipeline from bulging. Alternatively, the area containing the damage can be encapsulated to contain any leak that may occur. The predominant method of reinforcing or encapsulating damage in cross-country pipelines is to install a Full-Encirclement Repair Sleeve.
We produce sizes ranging from 3.5″ ID up to 60″ ID, 120″ lengths and thickness ranging from 5/16″ up to 3/4″
Milled Groove for Backing Strip is available.
Type A Sleeve (Reinforcing)
Type A Sleeve Ends are not Welded Circumferentially to the Carrier Pipe. The Type A sleeve is not capable of containing Internal Pressure but functions as reinforcement for a Defective area. It is only used for the repair of defects that are not leaking and that are not expected to grow during service, or when the damage mechanism and growth rate are fully understood.
Type A Sleeve is made by two curved piece of Steel Plates or Two Cylinfrical Halves of Pipe that are wrap arounf the Carrier Pipe the Defective Area and After Positioning, they are joined by Welded the Side Seams
Type B Sleeve (Pressure Containing)
Type B sleeve ends are welded circumferentially to the carrier pipe. A Type B sleeve is capable of containing internal pressure because the ends are fillet welded to the carrier pipe. Type B sleeves can be used to repair leaking defects or defects that may eventually leak and to strengthen pipe having defects that reduce the axial load carrying capability of the pipe. The ends of a Type B sleeve are fillet welded to the carrier pipe. Since its ends are attached to the carrier pipe, a Type B sleeve can be used to repair leaks and to strengthen circumferentially oriented defects.
In fact, a Type B sleeve has been used in place of a girth weld to make a tie-in on a pipeline. Because a Type B sleeve may contain pressure and/or carry a substantial longitudinal stress imposed on the pipeline by lateral loads, it should be designed to carry the full pressure of the carrier pipe. Additionally, it should be carefully fabricated and inspected to ensure its integrity.
