Abulaila Flanges is a focused manufacturer and supplier in Amman, Jordan, providing high‑performance AISI 4130 flanges for demanding pressure, temperature, and mechanical conditions in energy and industrial projects. The company aims to deliver dimensionally accurate, heat‑treatable alloy‑steel flanges that combine strength, toughness, and weldability for critical piping systems in oil and gas, petrochemical, and power sectors. With project‑driven service, flexible sizes, and adherence to common international standards, Abulaila Flanges supports EPC contractors, fabricators, and maintenance teams in securing reliable AISI 4130 flanges for new installations, shutdowns, and brownfield upgrades
AISI 4130 is a low‑alloy chromium‑molybdenum steel typically containing about 0.28–0.33% carbon, 0.8–1.1% chromium, 0.15–0.25% molybdenum, plus manganese, silicon, and trace elements, with the balance iron. This composition provides a good combination of hardenability, strength, and toughness after appropriate heat treatment such as quenching and tempering. AISI 4130 flanges can achieve high tensile and yield strengths with good impact resistance and fatigue performance, while maintaining reasonable weldability when controlled procedures and post‑weld heat treatment are applied where necessary.

Abulaila Flanges, a leading supplier in Amman, Jordan, offers an extensive selection of AISI 4130 Flanges, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges. Designed for diverse industrial applications, our high-quality inventory and commitment to exceptional service make us a trusted choice for flange products in the region.
AISI 4130 flanges are widely used in applications requiring high strength‑to‑weight ratio and dependable performance under pressure, temperature, and cyclic loading. Typical uses include wellhead assemblies, manifolds, choke and kill lines, blowout preventer (BOP) connections, drilling and completion equipment, and high‑pressure process piping in oil and gas and petrochemical plants. They are also used in power generation, hydraulic systems, and structural joints in heavy engineering where alloy‑steel flanges are preferred over carbon steel. Proper heat treatment, machining, and inspection help ensure these flanges deliver long, reliable service in critical, safety‑sensitive environments.
