Purpose Use of Rubber Lining

The purpose of the use of rubber lining is to protect an equipment against corrosion / rust and chemicals that abbrasive and other ingredients such as sea water, acid, sand, slurry, etc., which can damage an equipment.

Material & Specification

Lining Method for Hot Bonding

• All substrate surface to be lined is inspected visually before shotblasting.
• All Surfaces to be lined shall be blasted.

• 2. Adhesive Application
• 1. Surface Preparation

Primer

Application of the Rubber Sheet

• 1. Individual sheet shall be spread on

the working table and edges shall be beveled to make overlap scraf joints. Overlap scraf joints shall be made so that the overlap follow the direction

• f flow.
• 2. Applying the lining sheet to the

substrate.

• 3. All sheet and joints shall be checked

visually and pinholes testing shall be done to detect defects.

• 4. Rubber sheet edge shell be cut

scantly at the width about 2,5t using soldering iron of knife.

• 5. For joints, the length of overlap is

about 10 – 30 mm for shell and flat area, and internal support and flange area will be 10 – 30 mm.

Curing Procedure

• Steam pressure shall be kept constantly
• Curing Steam pressure max 4,0 kg/cm²
• Time max 4 hours
• 1. Autoclave Cure
• 2. Exhaust Steam Cure

The equipment which can not be put into autoclave shall be cured with steam at ambient pressure.

Inspection Procedure

• 1. Surface Cleanliness
• 2. Quality of the lining and bonding materials
• 3. Visual check before curing
• 4. Visual check after curing
• 5. Hardness Test
• 6. Spark Test / Pinhole Test
• 7. Bonding Strength Test
