Rubber Linings

Over the years, the Regal Group has become increasingly involved with the rubber lining of bespoke, offshore and marine products, tanks, chutes, pipework, etc.

Rubber lining is a specific coating method used to protect various engineered products and systems. The coatings are applied to prepared surfaces, usually by hand and must be chemical, seawater resistant, etc. The linings are ‘vulcanised’ ensuring they are fully bonded to the coated surface.

The Regal Rubber Group has three large electric and steam vulcanisers, including one of the biggest in the UK, therefore we can undertake some of the largest and most complex rubber linings!

Regal Rubber have completed many Caisson guide and clamp lining contracts for a multitude of oil and gas platforms and more recently, J-tube lining for off-shore wind-farm installations.

These linings are generally manufactured with our ribbed, seawater grade neoprene compound, and can be either hot or cold bonded to the inside surfaces of the guides.

(Cold bonding is done with special epoxy-based resins whilst hot bonding is done using rubber-to-metal proprietary adhesives and vulcanised in an autoclave).

Typical Manufacturing Procedure:

Inspection of guide or clamp metalwork.
Guide is marked with unique I.D. number.
Metal de-greased if necessary, prior to grit-blasting.
Inside guide surfaces grit-blasted to ISO 8502-3.
Metal surfaces coated with primer and proprietary adhesives.
Rubber compound tested to BS 903
Rubber lining applied to inside metal surface.
Hot bonded guides are cured inside computer controlled vulcanizer.
Finished linings inspected for hardness and dimensional accuracy.

Rubber Lining of Trawler Boat Sheaves

The puretic power block is a special kind of mechanised winch used to haul nets on fishing vessels. The power block is a large powered aluminium pulley incorporating a ‘V’ or ‘W’ shaped sheave which is

protected with a specially designed neoprene rubber coating. At one time many men were needed for the back-breaking work of hauling a purse seine manually however the same work can now be

carried out with fewer men using a power block. The puretic power block revolutionised the technology of hauling fishing nets, particularly purse seine nets.

These rubber lined ‘sheaves’ come in various shapes and sizes, all of which can be successfully rubber lined with Regal’s seawater grade rubber compounds.
