Quality Assurance & Testing
Every lining and coating job is executed under strict QA/QC protocols. We maintain detailed inspection and test plans (ITPs) including spark testing, adhesion testing, hardness verification,and dimensional checks. Our lab is equipped with Rheometers, Tensile Testers, Ageing Ovens,Abrasion Testers, and precision gauges to ensure material and process conformity.
Our Process
- Surface Preparation – abrasive blasting and inspection
- Primer & Adhesive Application – multi-coat bonding system
- Lining Application – sheet or spray applied lining with skilled workmanship
- Vulcanization / Curing – autoclave or field curing for strong adhesion
- QA/QC Inspection – spark test, DFT measurement, visual and adhesion verification
Advantages of Industrial Linings
- Protects against corrosion, erosion, and abrasion
- Extends equipment life by up to 5–10 years
- Reduces maintenance and unplanned shutdowns
- Prevents contamination and product loss
- Improves process safety and reliability.
Why Rubber Lining?
Rubber lining is a protective barrier applied to internal surfaces of steel equipment to resist:
- Corrosion caused by acids, alkalis, and salts
- Erosion due to slurry and particulate flow
- Abrasion in mining and material handling systems
- Chemical attack in process industries
Using advanced vulcanized rubber technology, Diode Trading ensures maximum adhesion,uniform lining thickness, and leak-proof sealing for extended service life.
