About
Henriques and Henriques, S.A., founded in 1980 by Saul Henriques and based in Santarem, Portugal, is a pressure vessel and metal tank manufacturer forming part of the Henriques Group SGPS alongside Petrometal and Ecodepur. The company fabricates vessels up to 5 meters in diameter and 30 meters in length using submerged arc welding and semi-automatic MIG/MAG processes. All pressure equipment is designed to the European Pressure Equipment Directive PED 97/23/EC with additional compliance to PD5500, CODAP2000, AD-MERKBLATTER, EN13445, and ASME VIII-Div.1. In the water and environmental sector, Henriques and Henriques produces bladder-type and bladder-free surge vessels for potable water pressure maintenance and surge protection, water storage tanks from 100 liters to 120,000 liters or custom sizes, filters for water and gas treatment, vacuum collection tanks for sanitation systems, and steel tanks for compact wastewater treatment stations. The oil and gas division manufactures underground and aboveground single and double-skin fuel tanks (with steel, polyethylene, and fiberglass secondary containment), LPG storage tanks for aboveground and underground installation, autogas skids, and API-standard petroleum storage tanks. Additional products include compressed air receivers, reactors, heat exchangers, deaerators, pressurized and atmospheric silos, and hyperbaric chamber vessels. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications and has delivered projects to Qatar, Jordan, Oman, Belgium, and Spain.
