What We Do

Protecting steel from the chemistry that would destroy it

Rubber lining is the application of a chemical-resistant elastomer barrier between steel substrates and aggressive process media. It's one of the most effective and cost-efficient methods for extending equipment life in chemical, mining, and power industries.

With HAW Linings and GBT (Germany) as part of the Jasmino group, we bring 40+ years of European lining expertise combined with the manufacturing scale of our Indian facilities.

Our linings go directly onto equipment we've designed and manufactured — meaning surface preparation, geometry access, and application schedule are all coordinated from the start. No handoff gaps.

Material Selection

Right rubber for the right chemistry

Each elastomer has a specific resistance profile. We select and compound based on your exact process conditions.

NR — Natural Rubber

Soft & Hard · 40–70 Shore A

The workhorse for mineral acid environments. Excellent abrasion resistance and elasticity. Hot-vulcanised application for maximum adhesion.

H&sub2;SO&sub4;HClH&sub3;PO&sub4;Brine
IIR — Butyl Rubber

Isobutylene-Isoprene

Superior resistance to oxidising acids and excellent gas impermeability. Ideal for mixed acid environments and elevated temperatures.

HNO&sub3;H&sub2;CrO&sub4;Mixed Acids
CSM — CSM (Hypalon)

Chlorosulphonated PE

Broad chemical resistance with excellent weathering and ozone performance. The go-to for FGD systems in power plants.

FGDChlorineOzoneUV
EP — EPDM

Ethylene Propylene Diene

Outstanding resistance to steam, hot water, and dilute acids. Excellent flexibility at low temperatures. Widely used in water treatment.

Application Process

Seven steps to a defect-free lining

Every lining follows a controlled process from surface inspection to final spark testing. No shortcuts.

100%
Spark test coverage
Step 01 — Surface Inspection
Incoming steel surface assessed for weld quality, sharp edges, and surface profile. All weld grinding and corner radiusing completed before blasting.
Step 02 — Abrasive Blast Cleaning
Steel blasted to Sa 2½ (ISO 8501-1) with angular grit to achieve 50–75μm anchor profile.
Sa 2½50–75μmISO 8501-1
Step 03 — Primer Application
Bonding agent applied within 4 hours of blasting. Two-coat system chemically matched to the specific elastomer.
Step 04 — Sheet Laying & Consolidation
Calendered rubber sheet hand-applied with roller consolidation to eliminate trapped air. Seams overlapped and stitched.
Step 05 — Vulcanisation
Hot vulcanisation via autoclave or open cure. Temperature, pressure, and time monitored by data loggers.

Step 06 — Spark Testing
100% holiday detection at specified voltage per lining thickness. Every square centimetre tested.

Step 07 — Final Inspection & Documentation
Hardness, thickness, adhesion pull-off tests. Complete documentation with test certificates and cure records.
