Yorkshire Rubber linings Ltd take delivery of large 100% rubber lined cell tank. The old lining will be removed by pyrolysis control, grit blasted to Sa2.5, line internally with 10mm thick N270 and externally with 3mm thick N270, autoclave vulcanise and spark test

Prior to the cell tank undergoing pyrolysis control to remove the old lining careful documenting is recorded of the old lining to use a guide along with the drawings to make sure that the rubber lining is correctly applied.

After the pyrolysis cycle the cell tank is unloaded ready for metal inspection, on the photo you can see the residue of ash still left on the cell tank that was the rubber lining.

On close inspection it is visible that the cell tank requires metal repairs, here you can see the result of what chemical attack does to unexposed metal or an area were the lining has failed due to mechanical damage.

This photo shows more evidence of chemical attack on the steel suture around the bolt holes.

Metal corrosion of the inner section of the cell tank,

After a inspection of the metal fabrication repairs begins on the cell tank, our qualified fabrication team carry out the repairs in our on site fabrication shop.

After completion of the metal fabrication repairs the unit is then shotblasted to SA 2.5 it is then blown down to remove any dust and then moved to the rubber lining production area ready for rubber lining. This photos show our skilled operative applying the bonding agent to the freshly prepared shotblasted steel.

After the tank has been prepared with the bonding agent, it is then left to dry, once the bonding agent is dry, the rubber lining commences. This tank is 100% rubber lined so the smaller most difficult areas are started first, this photo shows the difficulties sometimes associated with rubber lining a tank or vessel 100%.

Careful and precision application of the rubber seams can be seen taking place in this photo, each seam has to be 100% spark proof

Each section of rubber has to cut to size with the correct bevel edging to ensure that each section of rubber correctly fits.

YRL Operative carrying out stitching "jointing of the seams"

Some section of the unit requires a thicker rubber lining. Each section of the unit has be carefully rubber lined to make sure that air is not trapped between each layer of the rubber.

Outside area almost completed

Last of the tricky section are completed

Once the rubber lining has been completed it is then loaded into the largest of our autoclaves, operatives can be seen here carefully loading the unit

Quality Control, the unit undergoing final inspection after vulcanization. final inspection incudes a full 100% spark test, hardness check and visual test.

Unit is carefully loaded into place.

Safely loaded ready for despatch to customer
