Heavy Wall Pressure Vessel (HWPV) Facility

L&T Hydrocarbon Saudi IMF, supported by L&T’s Heavy Engineering business, and widely recognized as the Heavy Wall Pressure Vessel (HWPV) Facility, is located in Jubail, KSA—one of the largest industrial areas in the world. Situated within the Royal Commission Jubail Industrial Area-1, this facility was established as part of Larsen & Toubro’s vision to bring advanced fabrication technology to the Kingdom. The HWPV is committed to developing local Saudi talent and leveraging smart manufacturing solutions to deliver world-class fabrication services to industries across the region.

In a short span, the facility has secured multiple 9COM approvals from Aramco and is actively contributing to several Aramco projects. It is also accredited with ASME U, U2, S, R and NB along with ISO 9001 : 2015, 14001, 45001, 29001 certifications. HWPV operates with an experienced team managing the entire process—from design to dispatch—independently from the KSA facility.

The facility boasts state-of-the-art infrastructure, including:

Robotic welding stations
Smart circumferential and longitudinal seam welding stations
CNC cutting machines capable of handling plates up to 350 mm thick
The region’s largest heat treatment furnace (12 m × 12 m × 45 m)
Advanced NDT capabilities such as PAUT and TOFD

Additionally, the facility supports local industry with site repair services. Our shops have the capacity to manufacture equipment in mono- and multi-wall constructions using a wide range of materials, including carbon steel, stainless steel, Monel, titanium, high-nickel alloys, and CrMoV alloy steels.
