Flanges are a critical component in any piping system, providing the mechanical joints that allow pipelines to be assembled, maintained, and modified without cutting. The quality, dimensional accuracy, and material integrity of your flanges directly affect the safety and reliability of the systems they connect. At OIS Middle East, we supply only from approved manufacturers with full material certification and dimensional compliance.
Types of Flanges We Supply
Our flange inventory covers all standard types required for industrial piping applications. Weldneck flanges are our most popular product, providing the highest level of structural integrity and preferred for critical, high-pressure, and high-temperature service. Slip-on flanges offer ease of installation and are suitable for general service applications. Blind flanges are used to terminate pipe runs or close off vessel nozzles and are stocked across the full pressure class range.
We also supply socket weld flanges for small-diameter, high-pressure applications, threaded flanges for low-pressure non-welded connections, lap joint flanges for use with stub ends in alloy piping systems, and reducing flanges for transitions between pipe sizes. Orifice flanges for flow measurement installations are available on request. Our breadth of stocking positions means that most standard requirements can be fulfilled from our immediate inventory.
Quality and Certification
Every flange supplied by OIS Middle East comes with full material traceability to EN 10204 3.1. Dimensional inspection is carried out per ASME B16.5 and ASME B16.47 as applicable. Flanges are independently inspected prior to dispatch and can be subject to third-party witnessed inspection by client-nominated bodies such as Bureau Veritas, SGS, Lloyd’s Register, or equivalent.
