Purpose Use of Rubber Lining
The purpose of the use of rubber lining is toprotect an equipment against corrosion / rust andchemicals that abbrasive and other ingredients suchas sea water, acid, sand, slurry, etc., which candamage 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.
Rubber Sheet
Rubber Adhesive
Bonding Agent
Substrate/Steel
2. Adhesive Application
1. Surface Preparation
Primer
Application of the Rubber Sheet1. Individual sheet shall be spread on
the working table and edges shall bebeveled to make overlap scraf joints.Overlap scraf joints shall be made sothat the overlap follow the directionof flow.
2. Applying the lining sheet to thesubstrate.
3. All sheet and joints shall be checkedvisually and pinholes testing shall bedone to detect defects.
4. Rubber sheet edge shell be cutscantly at the width about 2,5t usingsoldering iron of knife.
5. For joints, the length of overlap isabout 10 – 30 mm for shell and flatarea, and internal support andflange 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 notbe put into autoclave shall becured with steam at ambientpressure.
Inspection Procedure
