Stud Bolts
Product Specifications
OIS Middle East is a leading supplier and exporter of industrial stud bolts and fastening products in the UAE, supporting major Oil & Gas, petrochemical, refinery, offshore, marine, and infrastructure projects across the Middle East and Africa. We maintain extensive ready stock of carbon steel and stainless steel stud bolts in multiple grades, thread configurations, coatings, and dimensions for urgent project requirements and shutdown maintenance operations.
Stud bolts are critical fastening components used primarily in flange connections operating under high pressure and elevated temperature conditions. In industries such as Oil & Gas and petrochemicals, the quality of bolting materials directly impacts operational safety and plant reliability. OIS Middle East supplies only certified stud bolts sourced from approved manufacturers with full material traceability and dimensional compliance.
Industrial Valves
Our valve range covers the most widely used valve types in industrial piping, across a broad range of materials, pressure classes, and sizes. We supply cast steel valves for high-pressure and elevated-temperature service, cast iron valves for general-purpose low-pressure applications, and stainless steel valves for corrosive service environments. Our valve types include gate valves, globe valves, check valves, ball valves, and butterfly valves across a range of end connections including flanged, butt-weld, and socket weld.
Cast steel valves are manufactured from carbon steel or low-alloy steel castings and are designed for demanding service conditions in Oil & Gas facilities, refineries, and power plants. They are typically specified to ASME B16.34 and are available in pressure classes from #150 to #2500. Our cast iron valves serve the lower-pressure requirements of water treatment, HVAC, and general utilities piping, while our stainless steel valves provide the corrosion resistance needed for chemical, food, and pharmaceutical piping systems.
