Manufacturer of Pipe Sleeve
We, Manufacture a Full Line of Pre-Stressed Metallic Sleeve. We Supply Pre-Stress Metallic Sleeves Worldwide, for Oil and Gas Industries.
They are supplied are used for Pipeline Defects Repair by the Shielded Metal Arc Welding Process (SMAW). The Pipelines Repaired are Manufactured by the Electric Resistance Welding (ERW) Technique.
The Specification of Material of Construction is -
The Pre-Stressed Metallic 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.
The Sleeves shall be Manufactured to the Standard Lengths of 1.0 m and 3.0 m for any Diameter of Pipe.
The backing strips shall be manufactured in standard lengths of 3m.
We can manufacture Pre-stressed Metallic Sleeve for any Size Depending on the Client's Requirement.
