Half repair Pipe Sleeve

Half repair Pipe Sleeve

» General

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. 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.

» 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 245000 / 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

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 as per clients requirements.

» 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.

» Milling of Half Repair Pipe Sleeves for backing Strips

Half repair pipe sleeves can be milled on the inside longitudinal edges for the backing strips. Depth of 1/16" (.625) -0" + 1/32" and width 5/8" (.625) -0 + 1/16" on each side. Outside longitudinal edges are beveled 30° (+5° - 0°) for welding.

» Backing Strips

Backing Strips are hot rolled commercial carbon steel sheet and strips of commercial quality. A-569 / A1011 SS GR33 / IS:2062 or equivalent in coils and cut lengths having a maximum carbon of 0.15%. 1 1/4" wide, 16 gauge (.0598) with a tolerance of min. 0.0538 - max 0.0658, 10' long, precrimped (10 degree total bend).

ASTM steel composition of A569/A1011 SS GR33/IS:2062:

Carbon (Max) Manganese (Max) Phosphorus (Max) Sulphur (Max) Copper (when specified)
0.15 0.60 0.036 0.035 0.20 min.


» Mechanical Properties and Testing

Mill test reports will be furnished on all materials. If stock plate is not available with a maximum hardness guarantee independent testing may be performed to check the hardness on stock plate and this report will be submitted along with ptoduct. If required additional testing reports will be furnished which includes destructive, magnetic particle, liquid penetrate, ultrasonic and radiographic reportrs carried out by a reputed third party.

» Dimensional Requirements

Longitudinal edges to be beveled to 30 degrees (+5 degrees -0 degrees), with a root face (land of 1/16" (+-1/32"). Inside diameter (I.D.) of each Half pipe repair sleeve will be fabricated to match the outside diameter (O.D.) of Standard nominal line pipe (bare with tolerance of:

Wall Thickness Half Pipe ID Size Tolerance
3/16", 1/4" plate 2" thru 12" (+0"-1/8")
3/16", 1/4" plate 14" thru 42" (+0"-1/4")
5/16" plate 6" thru 12" (+0"-1/8")
5/16" plate 14" thru 42" (+0"-3/16")
3/8" plate 8" thru 12" (+1/8"-0")
3/8" plate 14" thru 20" (+1/16"-1/16")
3/8" plate 22" thru 42" (+0"-1/4")
1/2" plate 12" thru 20" (+1/16"-1/16")
1/2" plate 22" thru 42" (+1/8"-1/8")

Half repair sleeves can be manufactures in such a way that when two (2) halves of the sleeve are placed on the pipe, their total circumference shall equal the circumference of the pipe minus a gap between the longitudinal edges on either side of 1/16" (-1/16" + 1/32") for welding.

» Size

We can manufacture in any size and also as per client's requirement.
