Half pipe Sleeves

Half Repair pipe Sleeves 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.

Material used are structural quality carbon steel or pressure vessel quality carbon steel plates, which are to ASTM specifications, and in the following grades: ASTM A36 (structural; minimum yield 36,000 psi) ASTM A572 GR50 (structural; minimum yield 50,000 psi) ASTM A572 GR65 (structural; minimum yield 65,000 psi) ASTM A516 GR70 (pressure vessel; minimum yield 38,000 psi) ASTM A537 Class I (pressure vessel; minimum yield 50,000 psi) 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.

Manufacturing

Half Repair Pipe Sleeve 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 of: Pipe O.D. Size | Sleeve Length 2" thru 3 1/2" = 5' 0” 4" thru 12" = 10' 0” 14" thru 16" = 8' 0”
