Pipe supports are used to eliminate damage at the pipe crossings caused due to lateral or linear movement of pipes and are ideal for use between pipe & pipe supporting structures or at pipe crossings. They also find usage as structural supports / expansion plates for boilers, pressure vessels, air pre-heaters, electro static precipitators etc. These sliding bearing supports permit unrestricted movement at free end, owing to the changes in temperature or during loading / unloading or due to seismic effect. If the supports are rigid, stress will be developed at the supports & causing major damages to the structure.

Pipe / structural supports are generally designed to meet the requirements of BS 5400 standard section 9.1. Rollon bearings design & manufacture the pipe supports / structural supports with ROLLON TB SLIDEWAY material as the interface material. ROLLON TB SLIDEWAY is a composite material consisting of PTFE & sintered bronze along with special wear resistant additives. It is a self-lubricating, wear resistant material suitable for temperatures up to 260° c and not effected by weather & most chemicals.

We can also supply the sliding supports with interface material in virgin PTFE, graphite or any filled PTFE  to suit the customers specification.

The pipe / structural supports consist of lower plate & upper plate. The lower plate shall be of ROLLON TB SLIDEWAY material suitably bonded on to the carbon steel plate, the upper plate shall be made of 1.5MM thick stainless steel (SS 304) tack welded to the backing carbon steel plates. The assembly is so designed that upper plate is larger than the lower plate by an amount in excess of the expected movement, so keeping the contact area constant throughout the cycle of motion.
The bearings are designed to accommodate the lateral & longitudinal movements anticipated in the structure. We can also design the bearings to accommodate any rotational movements or bearings with capacity to self align during erection. Such bearings can be designed up to maximum vertical load of 250mt & horizontal load of 50mt.

We can also manufacture bearings with elastomeric backing, this will accommodate small angular misalignments.

SKIVING : Billets are skived to the required thickness in the state of the art, CNC SKIVING MACHINE which ensures uniform & consistent thickness with very close tolerances.

ETCHING PLANT : In order to achieve perfect bonding of the skived material , the interface materials is chemically etched on one surface of the material. The chemical etching on one surface ensures perfect bonding. Rollon provides the Industry's highest quality etched surface for superior bonding characteristics.

TENSILE STRENGTH : We also have in our inspection lab, tensile testing machine enabling us to conduct necessary test for every skived sheet. These tests are conducted as per ASTM D1457

MACHINING : Rollon has various other machining facilities like centreless grinder, vertical surface grinder, universal cylindrical grinder, lathes, drilling machines, etc,. Enabling us to have control over the entire manufacturing.

TESTING :  Rollon has the in-house facility to conduct the load, both vertical & horizontal & friction test on the structural supports manufactured. The test rigs are calibrated regularly.
