INSULATION AND RUBBER LINING

1. Insulation

Insulation is used to reduce heat loss, prevent condensation, and provide personnel protection in industrial, commercial, and residential applications.

Types of Insulation

✅ Thermal Insulation – Prevents heat transfer in piping, equipment, and buildings.
✅ Cryogenic Insulation – Used for extremely low temperatures (e.g., LNG tanks).
✅ Acoustic Insulation – Reduces noise in industrial plants and buildings.
✅ Electrical Insulation – Prevents electrical conductivity in power systems.

Common Insulation Materials

  • Mineral Wool – Fire-resistant, used in industrial piping and HVAC systems.

  • Fiberglass – Lightweight, commonly used for buildings and ductwork.

  • Calcium Silicate – High-temperature resistance, used in refineries and power plants.

  • Foam Glass – Non-combustible, used in cryogenic applications.

  • Aerogel – Advanced, ultra-light, and highly efficient insulation

Applications of Insulation

🏭 Industrial piping and boilers
🏢 HVAC ductwork
🚢 Marine and offshore structures
⚡ Electrical panels and transformers

 

2. Rubber Lining

Rubber lining is applied to tanks, pipes, and equipment to protect against corrosion, abrasion, and chemical attack.

Types of Rubber Lining

✅ Hard Rubber Lining – Used for chemical resistance in tanks and reactors.
✅ Soft Rubber Lining – Flexible and used for abrasion protection in chutes and pipes.
✅ Natural Rubber Lining – Resistant to acids and alkalis.
✅ Neoprene Lining – Excellent oil and weather resistance.
✅ EPDM Rubber Lining – Resistant to heat, steam, and UV exposure.

Rubber Lining Process

  1. Surface Preparation – Cleaning and roughening the surface.

  2. Adhesive Application – Applying bonding agents for adhesion.

  3. Rubber Sheet Installation – Lining is applied manually or vulcanized.

  4. Curing/Vulcanization – Heat or chemicals are used to set the rubber.

  5. Inspection & Testing – Spark testing and adhesion checks ensure quality.

Applications of Rubber Lining

🏭 Chemical Storage Tanks – Protects against aggressive chemicals.
⛏ Mining Equipment – Reduces wear and tear in slurry pipes.
🚢 Marine & Offshore – Used in seawater pipelines.
⚙ Power Plants – Protects scrubbers and ductwork.
