In any chemical industries floors, drains, storage & reaction vessels etc., require suitable lining to prevent corrosion, normally a layer is required for Protection. The Company set up its Rubber Lining Division in 2000, for the manufacture of corrosion resistant and abrasion resistant Rubber Linings and other Rubber Lined products for industrial applications and has been a major player since then.
For process equipment vessels, storage tanks, ducts, columns and other specialized items.
Rubber Lining is thin layer of coating apply on inner & outer surface of vessels & pipes for protection.
The sandblasting operation is done under high pressure to smooth a rough surface, roughen a smooth/Shape the surface to remove its contaminants"
With a pulley lagging system, your pulley and conveyor belt remain in contact at all times. This increases friction and prevents the belt from slipping – which would otherwise rapidly ruin your belt, especially at high rotation speeds.
Rubber linings have been used successfully in equipment for the manufacture, storage and transportation of phosphoric acid for many years. It is the most cost-effective material for preventing corrosion when the correct material is selected and the application is done properly.
Rubber Lining is the skilled application and bonding of rubber sheet to specially prepared surfaces. The rubber can be applied as either unvulcanised material which is then vulcanised and hot bonded – usually in a steam autoclave; or as pre vulcanised material which is cold bonded using two part adhesives. The fully bonded lining provides a durable and resilient protective rubber coating that will withstand very aggressive process conditions and applications.
It is necessary to have a good understanding of the various service conditions, rubber linings suitable for these conditions, and proper procedures for application and curing in order to obtain a long and trouble-free service life.
Temperatures can range from 140°F (60°C) to over 200°F (93°C). The concentrations can be from 28% to over 70%. The solution may be under pressure, static storage or under full vacuum. Under these conditions, the acid is highly corrosive and requires the best efforts of all parties to yield a rubber lining that will give the desired service life. The following sections will go into some detail to explain the steps required to accomplish a successful rubber lining project.
The resistance of various different types of Tank rubber lining and solvents vary greatly.
Soft Natural Rubber : This Rubber has an excellent resistance to Hydrochloric and Sulfuric Solutions.
Ebonite Rubber : This Rubber has higher degree of chemical resistance & Hardness and is widely use in the Electro-Plating and metal finishing industry.
Synthetic Rubbers : Synthetic Rubbers such as Butyl, Hypalon, Neoprene and Nitrile have good resistance to hydrocarbons and mineral oil and can be used in some circumstances between 80 to 90 degree C. We will be pleased to recommend a suitable rubber lining service.

The principal benefits of rubber lining are its excellent resistance to corrosive and abrasive chemicals and materials, e.g. acids, alkalis, salt water, slurries, sand, shot blast media, crushed rock etc. In addition rubber linings provide other benefits including noise and vibration reduction, electrical and thermal insulation and product protection.
