HALF PIPE SLEEVE
We are manufacturer of:
- Half Pipe Sleeve
- Half Sole Repair Sleeve
- Pre-Stressed Metallic Sleeve
- Leak Defect Repair Sleeve
- Split Sleeve
Pipeline Products Inc are designed to avoid a costly shut down. Existing lines can be cased without thru-put loss, because it is not necessary to shut down the carrier line to perform the required repair. A full scope of sizes, ASTM grades of steel plate (structural and pressure vessel quality), wall thickness and longitudinal edge options are available. Half Sole Repair Sleeves, also called split casing or half wrap, are custom-fabricated to your specifications, to assure a precision product and secure fit. There are four types of material available, two pressure-rated steels and two structural-grade steel. The pressure-rated steel sleeves can be used to repair leaking and non-leaking defects while the structural-grade steel sleeves can function as reinforcement for a defective area.
FEATURE
The steel repair sleeves can be used for internal and external corrosion, gouges, dents, grooves, arc burns, cracks, defective girth
welds, laminations and leaks. Pressure containing sleeves feature a wall thickness equal to or greater than required for the maximum allowable operating pressure or the full strength of the pipe being repaired. The steel Repair sleeve material is certified and the carbon equivalent will not exceed 0.45 percent. Each half-sole segment comes with one pre-crimped back-up strip.
Steel Repair Sleeves can be used as pads or cradles for above ground piping, drain tile supports and patches (segments in 90° and 180° arcs, from 6-inches to 10 feet in length are available as specials).
Each Steel Repair Sleeve has standard bevels with a back-up strip and material certifications. Sleeve ends are square cut. Back-up strip are not included with Standard Girth Weld Steel Repair Sleeves but are available as special order.
MATERIAL
Material used are structural quality carbon steel or pressure vessel quality carbon steel plates, which are to ASTM specifications, and in the following grades:
API 5L Gr B, X42, X46, X52, X56, X 60, X 65, X70 – PSL 1 – PSL2 (minimum yield 42000 / 52000 / 60000 / 65000 / 70000)
ASTM A36 (structural; minimum yield 36,000 psi) ASTM A572 GR42, GR50, GR55, GR60, GR65 (structural; minimum yield 29,000 psi) ASTM A516 GR55, GR60, GR65, GR70 (pressure vessel; minimum yield 38,000 psi) ASTM A537 Class I, Class 2, Class 3 (pressure vessel; minimum yield 50,000 psi) EN 10025 – S235, S275, S355, S450
The chemical composition does not exceed the percentages specified for the ASTM material ordered. Repair sleeves are fabricated from plate with low carbon equivalency for good weld ability.
The maximum allowable carbon equivalency (CE) quality carbon steel plates will be based on the heat analysis. The maximum allowable carbon equivalency (CE) pressure vessel quality carbon steel plates will be based on the heat analysis, in most cases.
Note : The sleeve can be manufactured in any grade as per the application & client requirements.
MANUFACTURING
Pipeline Products Inc is formed by rolling, step braking, or die forming without the use of heat treating.
Longitudinal edges of the Half Sole are beveled for welding, if requested, at 30º. The bevel are a mechanical type and/or produced by plasma torch burning.
Half Repair Pipe Sleeve ends have sheared square edges for fillet welding, unless square end bevel is requested, and are available in maximum lengths as per clients requirements.

CARBON STEEL & STAINLESS STEEL WELD ON REPAIR SLEEVE
Carbon Steel Weld on Repair Sleeve and Stainless Steel Weld on Repair Sleeve are designed to repair and reinforce in-service steel pipelines without shutdown or service disruption. Weld on Repair Sleeves are suitable for repair of weak or leaking areas caused by external/internal corrosion, damage (dents, gouges), inferior welds, defective piping material and other problematic causes.
This can be furnished as full body repair sleeves or partial repair sleeves depending on the application need. Fittings are supplies standard beveled for welding (square cut sleeve ends) and welding back up strips are available. Pressure grade and Structural grade materials are available in both carbon steel and stainless steel.
Weld On Repair Sleeve feature :
Immediate availability Built to exact pipe diameters for custom fit Material grades and thickness to application codes/requirements Restores host pipe to original & future expected service requirements Coatings for corrosion resistance
Beyond repair, Weld On Sleeves can be used to cradle, support, reinforce or pad pipelines in above ground piping systems.
PRE-STRESSED METALLIC SLEEVE
The pre-stressed sleeves are of full encirclement split type and are manufactured by a production process, that minimizes occurance mill defects. Axial edges of the sleeves are bevelled to form 60° weld angle on assembly for the horizontal butt joint. A recess on the inner side of each pair of half sleeves is machined (cut out) to accommodate a 3 mm thick by 18 mm wide backing strip along the horizontal joint. The backing strips are manufactured from the same material as the sleeves and supplied. Circumferential edges of the sleeves is pre- fabricated to form 90° lap joint with the pipe.
The internal diameter of the sleeves is designed and constructed so as to fit on the pipe withour leaving a gap between the inner surface of the sleeve and outer surface of the pipe all around.
On assembly prior to welding, the maximum root gap shall be 3.0 mm on both horizontal joints. A 1.5 mm root face shall be allowed on both edges.
Both the horizontal and circumferential edges shall have a smooth finish.
The sleeve surfaces shall be protected from corrosion by a suitable method such as coating with corrosion resistant paint or other acceptable methods.
LEAK DEFECT REPAIR SLEEVE
Lightweight for easy handling and installation. Eliminates costly downtime. Minimizes repair costs. Complies with CSA Z183 and ANSI B31.4 Standards.
ENCAPSULTAING SLEEVE
RUPTURE SLEEVE – ENCAPSULATING SLEEVEIt is a Pipe Repair TYPE B Sleeve used to enclose / encapsulate a CLAMP: TEMPORARY LEAK REPAIR CLAMP – Rupture Clamp or any other leak joint over the main Pipeline. It encloses the additional material like Clamp or Flange over the Pipe and forms a Full Encirclement Sleeve joint To give a full strength to the defected portion of the pipeline with the help of welding.
GIRTH WELD SLEEVE
The Steel Repair Sleeves can be used for internal and external corrosion, gouges, dents, grooves, arc burns, cracks, defective girth welds, laminations and leaks. Pressure containing sleeves feature a wall thickness equal to or greater than required for the maximum allowable operating pressure or the full strength of the pipe being repaired. The Steel Repair Sleeve material is certified and the carbon equivalent (long formula) will not exceed 0.45 percent. Each half-sole segment comes with one pre-crimped back-up strip. Steel Repair Sleeves can be used as pads or cradles for above ground piping, drain tile supports and patches (segments in 90° and 180° arcs, from 6-inches to 10-feet in length are available as specials). Each Steel Repair Sleeve has standard, longitudinal bevels with a back-up strip and material certifications. Sleeve ends are square cut. Back-up strips are not included with standard girth weld steel sleeve.
Materials used for Girth Weld Sleeve
ASTM specifications are followed to manufacture girth weld 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 the below-mentioned grades :
ASTM A572 GR50 ASTM A572 GR65 ASTM A516 GR70 ASTM A537 CL1
In addition to these, the sleeves can also be made in any custom grade as per the client usage.
