Gujarat India is home to one of the world’s most concentrated oil and gas processing corridors stretching from the Jamnagar refinery belt in the west to the petrochemical hubs of Dahej, Hazira, Bharuch, and Vadodara in the east. For EPC contractors, procurement engineers, and project managers working on oil and gas projects across this corridor, selecting the right cable gland supplier in Gujarat is a critical decision that directly impacts both installation safety and regulatory compliance. A cable gland is far more than a mechanical fitting in a hazardous refinery environment, it is a certified safety component that prevents the propagation of flame, gas, and explosive atmosphere into electrical enclosures.
Exgrip, headquartered in Udhyognagar, Jamnagar, Gujarat, is one of India’s leading manufacturers of ATEX certified, IECEx certified, and PESO approved explosion proof cable glands for oil and gas applications. With a complete product range covering double compression cable glands, single compression cable glands, and barrier glands available in brass, nickel-plated brass, and stainless steel Exgrip serves refineries, petrochemical plants, LNG terminals, and upstream oil and gas projects across Gujarat India and internationally. This guide covers everything procurement and engineering teams need to know when evaluating cable gland suppliers in Gujarat for oil and gas projects.
Why Gujarat is a Strategic Hub for Oil & Gas Cable Gland Supply?
Gujarat’s industrial geography makes it uniquely positioned as both a major consumer and manufacturer of cable glands for the oil and gas sector. The state hosts some of India’s largest and most complex energy infrastructure, creating consistent, large-volume demand for certified cable glands across project and maintenance phases.
Gujarat's Oil & Gas Industrial Corridor
Gujarat’s position as the largest refining state in India means that cable gland suppliers based in Gujarat particularly those located in Jamnagar, the brass manufacturing capital of India have a natural supply chain, logistics, and cost advantage for serving these industries.
The key refinery and petrochemical zones where cable gland demand is highest include:- Jamnagar: Home to the world’s largest single-location oil refining complex. Both public sector and private sector refineries in Jamnagar require ATEX and IECEx certified cable glands for Zone 1 and Zone 2 hazardous area installations throughout the refinery, terminal, and utility areas.
- Dahej: A major LNG import terminal and SEZ housing numerous petrochemical and specialty chemical projects. Dahej installations require cable glands rated for both gas hazardous areas and aggressive chemical environments.
- Hazira (Surat): A large integrated petrochemical complex with LNG, fertiliser, and chemical manufacturing plants all requiring extensive explosion proof cable gland installations.
- Bharuch and Ankleshwar: India’s largest GIDC chemical zone with hundreds of chemical and pharmaceutical manufacturing units requiring certified cable glands for hazardous process areas.
- Vadodara: Home to major petrochemical and polymer plants including GAIL and IPCL facilities requiring ATEX and IECEx certified cable glands for ongoing projects and maintenance.
Hazardous Area Requirements for Oil & Gas Cable Glands
Oil and gas facilities are classified as hazardous areas where flammable gases, vapours, or dusts may be present. Electrical equipment including cable glands installed in these areas must be rated and certified for the relevant zone classification. Using an uncertified or incorrectly rated cable gland in a hazardous area is not only a compliance failure; it is a serious safety risk that can result in equipment shutdown, legal liability, and in the worst case, ignition of an explosive atmosphere.
Hazardous Area Zone Classifications
| Zone | Atmosphere | Definition | Recommended Exgrip Model | Protection Type |
|---|---|---|---|---|
| Zone 1 | Gas / Vapour | Explosive atmosphere likely to occur in normal operation | E1FW (Double Compression) | Ex db IIC |
| Zone 2 | Gas / Vapour | Explosive atmosphere not likely in normal operation but may occur rarely | A2F (Single Compression) | Ex eb IIC |
| Zone 21 | Dust | Explosive dust atmosphere likely in normal operation | E1FW (Double Compression) | Ex tb IIIC |
| Zone 22 | Dust | Explosive dust atmosphere not likely in normal operation | A2F (Single Compression) | Ex tb IIIC |
Required Certifications for Oil & Gas Cable Glands in India
For cable glands used on oil and gas projects in India and Gujarat specifically, the following certifications are typically required or specified by project standards:
- ATEX Certification: Mandatory for projects with European-based clients or standards. Covers Ex db (flameproof), Ex eb (increased safety), and Ex ta (dust protection) protection modes.
- IECEx Certification: The international equivalent of ATEX, accepted in over 50 countries. Widely specified on international EPC projects in Indian refineries and petrochemical plants.
- PESO Approval: Required by the Petroleum and Explosives Safety Organisation (PESO) for electrical equipment installed in petroleum handling and storage facilities in India. PESO approval is mandatory for onshore oil and gas facilities governed by Indian petroleum regulations.
- IP66 / IP67 / IP68 Ratings: Dust-tight and water-resistant ratings required for outdoor refinery environments, cable trenches, and underground duct entries.
All Exgrip cable glands carry ATEX, IECEx, and PESO certifications and are rated IP66, IP67, and IP68 meeting the full certification requirements of Indian and international oil and gas project specifications. Visit the Technical page for full certification documentation and Ex marking details.
Cable Gland Types for Oil & Gas Applications
The selection of cable gland type for an oil and gas application depends on the cable construction (armoured or unarmoured), the hazardous area zone, and the environmental conditions at the installation point. Below is an overview of the main cable gland types used in Gujarat’s oil and gas industry.
Double Compression Cable Glands (Armoured Cables)
The double compression cable gland is the most commonly specified cable gland type for oil and gas projects. It is designed for use with steel wire armoured (SWA) and aluminium wire armoured (AWA) cables the standard cable constructions used for power distribution, instrumentation, and control wiring in refineries and petrochemical plants.
A double compression cable gland provides two independent mechanical seals: an inner compression that grips and bonds the cable armour layer, and an outer compression that seals the cable outer sheath. This dual-seal construction delivers the high IP rating and robust mechanical retention required for safety-critical oil and gas installations. Exgrip’s double compression range includes the E1FW, DCA, DCAB, DCU, and DCUB models, all rated Ex db for Zone 1 and Zone 2 hazardous area use.
Single Compression Cable Glands (Unarmoured Cables)
Single compression cable glands are used for unarmoured cables in oil and gas facilities typically for flexible instrument cables, control cables entering local control panels, and intrinsically safe field instrument wiring. Exgrip’s A2F, SCU, SCA, and SCUB models cover the full range of single compression applications, rated Ex eb for Zone 2 and selected Zone 1 installations.
Barrier Cable Glands
Barrier cable glands are used where cables pass through the wall of a flameproof (Ex d) enclosure. They prevent internal enclosure explosions from propagating back along the cable route. Exgrip’s DCAB, DCUB, and SCAB models are the barrier variants in the range and are essential for flameproof enclosure terminations in Zone 1 refinery installations.
Cable Gland Size Chart for Oil & Gas Applications
Selecting the right gland is just as important as choosing the right cable. That’s where the cable gland size chart and cable gland selection chart come in. These charts act as quick references to match the outer diameter of a cable with the correct gland size.

Material Selection: Brass vs Stainless Steel for Oil & Gas
Cable gland material selection for oil and gas projects in Gujarat depends on the specific installation environment within the facility. Three primary materials are used in refinery and petrochemical applications:
| Material | Best For | Advantages | Limitations |
|---|---|---|---|
| Brass | General refinery installations, process areas, MCC rooms, substations | Cost-effective, excellent machinability, good corrosion resistance, widely available from Jamnagar | Not suitable for highly acidic or chloride-rich environments |
| Nickel-Plated Brass | Outdoor installations, coastal and offshore-adjacent facilities, corrosive process areas | Enhanced corrosion resistance over standard brass, same mechanical properties | Higher cost than standard brass |
| Stainless Steel (SS316) | Highly corrosive environments, offshore platforms, LNG terminals, acid handling areas | Superior corrosion resistance, high mechanical strength, suitable for extreme chemical environments | Higher cost, heavier than brass |
For most onshore refinery and petrochemical installations in Gujarat’s industrial zones, brass cable glands are the standard specification. Nickel-plated brass is preferred for coastal and outdoor installations near the Jamnagar and Hazira coastlines. Stainless steel is typically reserved for LNG cold box areas, offshore-standard projects, and areas with aggressive chemical exposure.
