EW manufactures critical bolting for upstream, midstream and downstream oil & gas applications, including wellheads, Christmas trees, valves, pressure-control equipment, pipelines and process equipment.

Our capabilities include API 20E BSL-1 and BSL-2 fasteners, ASTM stud bolts, heavy hex bolts, heavy hex nuts and engineered fasteners for applications requiring controlled manufacturing and complete traceability.

Common materials and grades include ASTM A193 B7, B7M and B16; ASTM A320 L7, L7M and L43; ASTM A194 2H, 2HM, 7 and 7M, along with stainless steel and corrosion-resistant alloys.

Petrochemical facilities operate under combinations of pressure, temperature, corrosive media and continuous-duty service. Reliable bolting is essential across piping systems and process equipment.

IEW manufactures fasteners for valves, flanges, pressure vessels, heat exchangers, piping systems, pumps, compressors and associated process equipment.

Fasteners can be supplied in ASTM alloy steel, stainless steel, duplex, super duplex and nickel-alloy materials based on project and service requirements.

Refinery equipment requires bolting capable of maintaining joint integrity across high-temperature, high-pressure and corrosive operating environments.

IEW supplies stud bolts, tap-end studs, heavy hex bolts, heavy hex nuts and special engineered fasteners for refinery applications including valves, flanged joints, pressure vessels, heat exchangers, pumps and piping systems.

Products can be manufactured to applicable ASTM and ASME specifications with project-specific testing, coating and documentation requirements.

Offshore equipment places demanding requirements on bolting due to mechanical loading, corrosive environments and the importance of long-term reliability.

IEW manufactures critical fasteners for offshore drilling equipment, wellhead equipment, valves, riser-related equipment, pressure-control systems and other offshore applications.

Depending on the service environment, materials can include ASTM alloy steels, stainless steels, duplex, super duplex and nickel-based alloys.

LNG facilities require carefully selected bolting for equipment exposed to demanding process conditions, including low-temperature and cryogenic service.

IEW manufactures fasteners for LNG piping systems, valves, flanges, pressure equipment, heat exchangers, pumps and related process equipment.

Low-temperature bolting grades including applicable ASTM A320 materials and matching ASTM A194 nuts can be supplied in accordance with customer and project specifications.

Bolting used in power-generation equipment must perform reliably under combinations of temperature, pressure, vibration and cyclic loading.

IEW manufactures fasteners for turbines, boilers, pumps, heat exchangers, pressure equipment, piping systems and associated power-generation machinery.

Our manufacturing capability covers standard ASTM bolting as well as special fasteners manufactured to OEM drawings and application-specific requirements.

Chemical processing equipment requires bolting selected for the specific combination of mechanical loading, temperature and corrosion resistance.

IEW manufactures fasteners for reactors, pressure vessels, piping systems, valves, flanges, pumps and heat exchangers, with material options ranging from alloy steels and stainless steels to duplex, super duplex and nickel alloys.

IEW supplies engineered fasteners for marine and shipbuilding applications where strength, corrosion resistance and dimensional reliability are important.

Fasteners can be manufactured in alloy steel, stainless steel, duplex, super duplex and other corrosion-resistant materials based on the operating environment and customer specification.

Heavy-duty equipment used in mining and material-handling applications is subjected to high mechanical loads, vibration, impact and abrasive environments.

IEW manufactures high-strength bolts, nuts, studs, threaded components and custom fasteners for heavy industrial equipment and machinery.

IEW supports renewable-energy and associated industrial equipment manufacturers with high-strength and engineered fastening solutions.

Products can be manufactured for structural, mechanical, rotating-equipment and equipment-assembly applications based on customer drawings, specifications and project requirements.
