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.

Application Method of Rubber Lining 1. HOT BONDING Process Rubber Sheet Unvulcanized 2.COLD BONDING Process Rubber Sheet Vulcanized

Lining Method for Hot Bonding 1. Surface Preparation - All substrate surface to be lined is inspected visually before shotblasting. - All Surfaces to be lined shall be blasted. 2. Adhesive Application Rubber Sheet Rubber Adhesive Bonding Agent Primer Substrate/Stee l

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 10mm – 30 mm that the overlap follow the direction of flow. 2. Applying the lining sheet to the Rubber Sheet substrate. Substrate/Steel 3. All sheet and joints shall be checked visually and pinholes testing shall be done to detect defects. 2.5 x t 4. Rubber sheet edge shell be cut scantly at the width about 2,5t using soldering iron of knife. Rubber Sheet t 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 1. Autoclave Cure - Steam pressure shall be kept constantly - Curing Steam pressure max 4,0 kg/cm² - Time max 4 hours 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
