Industrial Flanges Supplier in Saudi Arabia

ASME B16.5 Industrial Flanges: Dimensions | Specifications | Material Grade | Standards | About Industrial Flange | All Product Types

Nutech Overseas is a trusted manufacturer and exporter of industrial flanges in Saudi Arabia, delivering high-quality piping components for oil & gas, petrochemical, refinery, and EPC projects. Our flanges are engineered in compliance with international standards such as ASME B16.5, ASME B16.47, EN 1092-1, DIN, and ISO, ensuring precision, durability, and superior performance in demanding industrial environments. With extensive export experience, we supply flanges to major industrial hubs across Saudi Arabia including Dammam, Riyadh, and Jeddah.

Product Overview

Industrial flanges play a critical role in piping systems by connecting pipes, valves, pumps, and other equipment. They provide a strong, leak-proof joint that can withstand high pressure and temperature conditions. Our industrial flanges are available in a wide range of sizes, pressure ratings, and material grades to meet diverse industrial requirements. Whether for upstream oil operations or downstream refining processes, our flanges ensure reliability and operational efficiency.

Types of Flanges We Supply

We offer a comprehensive range of industrial flanges including Industrial Flanges, Weld Neck Flanges, Blind Flanges, Socket Weld Flanges, Threaded Flanges, Ring Type Joint (RTJ) Flanges, Lap Joint Flanges, and Spectacle Blind Flanges. Each type is designed to meet specific operational requirements, providing flexibility for various piping systems. Weld Neck flanges are ideal for high-pressure applications, while Industrial Flanges are commonly used in low-pressure systems for easy installation.

Industrial Applications in Saudi Arabia

In Saudi Arabia, industrial flanges are widely used in oil refineries, petrochemical plants, offshore drilling platforms, and pipeline infrastructure. They are essential components in major projects under Saudi Aramco, as well as in power plants, desalination facilities, and industrial manufacturing units. Their ability to handle extreme pressure and temperature makes them suitable for critical applications in the energy sector.

Materials and Specifications

Our industrial flanges are manufactured using premium-grade materials such as Carbon Steel (ASTM A105, A350 LF2), Stainless Steel (ASTM A182 F304, F316), Alloy Steel (F11, F22), Duplex and Super Duplex Steel, and high-performance nickel alloys like Inconel and Hastelloy. These materials offer excellent corrosion resistance, mechanical strength, and long service life.

International Standards

All flanges are produced according to international standards including ASME B16.5, ASME B16.47 Series A & B, EN 1092-1, DIN, BS, JIS, and ISO. This ensures compatibility with global piping systems and compliance with project specifications.

Export strictly to Saudi Arabia

Nutech Overseas is a reliable exporter of industrial flanges to Saudi Arabia, providing complete documentation including mill test certificates, inspection reports, and compliance certificates. We ensure timely delivery and efficient logistics support for EPC contractors, OEMs, and industrial clients.

Advanced Manufacturing Capabilities

To meet the massive demands of Saudi Arabia's industrial sector, our production facilities employ state-of-the-art forging presses and automated CNC machining centers. This allows us to produce high volumes of industrial flanges with consistent dimensional accuracy. We specialize in producing large diameter flanges (up to 48 inches and above) under ASME B16.47 Series A and Series B, essential for main pipeline networks.

Meeting Saudi Aramco Specifications

Our flanges are engineered to meet and exceed the stringent requirements of major energy companies, including Saudi Aramco. This involves strict adherence to NACE MR0175/ISO 15156 standards for sour service environments. We ensure that our materials, particularly carbon steel and low-alloy steel flanges, have controlled hardness levels and undergo proper post-weld heat treatment (PWHT) to prevent sulfide stress cracking (SSC).

Logistics and Supply Chain Reliability

Understanding the critical timelines of mega-projects in Saudi Arabia, from NEOM to the expansion of Jubail industrial city, we maintain a robust supply chain. We keep a large inventory of standard size and pressure class flanges ready for immediate dispatch. Our logistics team handles all necessary export documentation, SASO SABER certifications, and customs clearance procedures to ensure fast and seamless delivery to Dammam, Jubail, and Yanbu.

High-Pressure Testing and Certification

Before any flange leaves our facility bound for Saudi Arabia, it undergoes comprehensive testing. Hydrostatic testing of flanged spools and precise dimensional checks using coordinate measuring machines (CMM) ensure zero-defect delivery. All products are accompanied by EN 10204 3.1 or 3.2 mill test certificates, providing full traceability of the steel heat from the steel mill to the finished flange.
