Rubber Lining Industry

The solids are thrown outwards against the wall of the vessel and then move away from the gas inlet and are collected in the conical base of the equipment. This separation process is very effective unless the gas contains a large proportion of solid particles less than 10 p in diameter and is equally effective when used with dust or mist-laden gases. The cyclone separators are obviously rubber lined to withstand wear at the velocity of gas and corrosion and are the most commonly used general purpose separator in the chemical process industry. 

Rubber to metal bonding is a generic phrase covering a number of interdependent processes. The rubber bonded units that result from the process are used for the isolation of noise and vibration in automotive, engineering and chemical industry applications, such as in rubber lining of process equipment. 

Hydrochloric acid is stored in rubber lined steel storage tanks and shipped in rubber lined tank cars, pot cars or glass carboys. The following commercial grades of hydrochloric acid are known synthetic hydrochloric acid which is prepared by the reaction of hydrogen with chlorine sulphate acid obtained as a by-product in the manufacture of sodium sulphate hydrochloric acid used in the foodstuff industry and finally chemically pure hydrochloric acid. 

This brilliant description of rubber lining and of its failure after providing the required performance of protection during even the shortest duration in the space industry is also relevant today for the application of rubber lining in chemical and other process industries the choice of materials, techniques and controls should be put into practice. 

Though for a number of years the application of rubber lining was limited to small fabricated tanks, vessels and pipes (which could be dealt with in a factory setting) the necessity arose to rubber line large storage tanks, ducts and vessels at clients sites and other outdoor installations due to the rapid growth, upgrading and modernisation of the chemical process industries. 

The outstanding property of rubber in general is resilience, or low modulus of elasticity. The flexibility and physical properties of rubber account for its application in general engineering and automobile industries whereas its chemical, wear and abrasion resistance as a sacrificial material, plus its insulating properties are utilised in many corrosion and erosion applications in process industries. Rubber lined mild steel, pipes and tankages have been standard materials of construction for hydrochloric acid service for many years. 

Rubber Lining for Corrosion Protection in the Chemical Industry... 

The technical advantages of a long-term nature are supplemented by considerable economic advantages. The combination of mild steel and rubber lining as materials of constructions in a chemical industry is much cheaper than stainless steel. An example is given by Heinrichs as [8] ...
