Wear & Abrasion
- Wear and Abrasion is the process of wearing down or rubbing away by means of friction
- Wear and Abrasion can also be found in wet and dry service conditions
- Excessive wear and abrasion results in substrate failure
Rubber Lining

Configuration of Rubber Lining




Corrosion Protective Lining
A protective layer that delayed the permeability of gas/vapor/liquid reaching the substrate

When vapor/liquid pass the lining layer, it will destroy the primer and causing delamination of lining layer

Specification of Rubber
When selecting rubber lining materials, the following physical properties shall be considered :
- Tensile strength
- Elongation at break
- Density
- Hardness
- Abrasion
- Rebound resilience
- Tear growth resistance

Type of Rubber Lining
Type of Rubber Lining Based on Curing System
1)Hot Lining System
2)Cold Lining System
Type o Rubber Lining Based on Hardness
1)Soft Rubber
2)Hard Rubber/ Ebonite Rubber
Most Popular Type Material of Rubber Lining:
- Natural Rubber
NR has good physical properties such as abrasive, tensile strength, tear strength and elongation break. Other that NR has good chemical resistance
- Butyl Rubber
Butyl rubber has Excellent chemical rubber, so butyl rubber suitable for chemical tank and other equipment with high concrentarion chemical.
- Chloroprene Rubber
Chloroprene rubber has excellent bonding, so the CR is commonly used for adhesive product. CR suitable for lining sea water equipment because CR has antibacterial sea water.
- Hard Rubber
Hard rubber is widely use as protective lining for highly corrosive substance at elevated temperature
- Sand-hard ( Soft-hard-soft )
The soft rubber outer layer against abrasion, when chemical permeate the soft rubber layer, it will be stopped by middle layer of hard rubber. The last layer of soft rubber form a strong bonding to the steel and also can take the thermal expansion of the tank.

Surface blast class (metal):

Sa 1 Light blast-cleaning. SSPC-SP-7
When viewed without magnification, the surface shall be free from visible oil, grease and dirt, and from poorly adhering mill scale, rust, paint coatings and foreign matter (see note 2). See photographs B Sa 1, C Sa 1 and D Sa 1.
Sa 2 Thorough blast-cleaning. SSPC-SP-6
When viewed without magnification, the surface shall be free from visible oil, grease and dirt, and from most of the mill scale, rust, paint coatings and foreign matter. Any residual contamination shall be firmly adhering (see note 2 below). See photographs B Sa 2, C Sa 2 and D Sa 2.
Sa 2½ Very thorough blast-cleaning. SSPC-SP-10
When viewed without magnification, the surface shall be free from visible oil, grease and dirt, and from mill scale, rust, paint coatings and foreign matter. Any remaining traces of contamination shall show only as slight stains in the form of spots or strippes. See photographes A Sa 2½, B Sa 2½, C Sa 2½ and D Sa 2½.
Sa 3 Blast-cleaning to visually clean steel. SSPC-SP-5
When viewed without magnification, the surface shall be free from visible oil, grease and dirt, and shall be free from mill scale, rust, paint coatings and foreign matter. It shall have a uniform metallic colour. See photographs A Sa 3, B Sa 3, C Sa 3 and D Sa 3.
RUST GRADE:
Surface Preparation Grades of Blast Cleaned Steel
Assessment of degree of removal of rust, mill scale and other visual containments
(inspected without magnification)
IMPORTANT NOTE:
Surface cleanness is not a measure of Surface profile. See the following pages for Notes on surface profile
Rust Grade A:
Steel with mill scale layer intact and very minor, or no rusting
Rust Grade B:
Steel with spreading surface rust, and the mill scale commenced flaking
Rust Grade C:
Rusty steel with the mill scale layer flaked and loose, or lost, but only minor occurrence of pitting
Rust Grade D:
Very rusty steel with the mill scale layer all rusted and extensive occurrence of pitting
