BAR WRAPPED STEEL CYLINDER (BWSC) PIPE

Manufacturing of BWSC pipe begins with fabricated steel cylinder with joint rings confirming to IS 15155:2002 which is hydraulically tested. A high rich cement mortar lining is placed at inner side of pipe by using centrifugally casting method. After the lining is cured, the steel cylinder is wrapped with MS bar, using slight tension in the bar. The size and spacing of the bar as well as thickness of the steel cylinder are proportioned to provide the required strength of the pipe. The steel cylinder and bar wrapping are covered with high rich cement mortar coating by using High Velocity impaction process.

As per IS 15155:2002 these pipes can be economically manufactured from diameter range from 250 mm to 1800 mm and upto 26 .length of each pipe shall be 5 m to 7.5 m. Higher diameter length pipes are also possible.

Advantages

These pipes have sliding overlap joint (rigid joint). Easy to assemble due to overlap weld joint, therefore can be installed rapidly and economically.

Pipe joint is rigid so there are less chances of leakage.

These pipes having higher structural integrity because of the interlocking of steel elements of pipe. composite construction greatly increase the rigidity of pipe beam strength and resistance impact..

These pipes made up of steel plate of lesser thickness than conventional steel pipes so it can be economical.

These pipes are improved steel pipe with high structural integrity and pipe stiffness at reduced price.
