About IPI

Founded in 1964, International Pipe Industries Corporation (IPI) is a pioneer in the manufacturing of large-diameter spiral welded steel pipes and fittings in the Philippines and Southeast Asia. Since beginning operations in 1967, IPI has continuously delivered high-quality piping solutions for water lines, infrastructure, and industrial applications—earning a strong reputation for reliability, innovation, and excellence in engineering.

Backed by decades of expertise, state-of-the-art manufacturing facilities, and ISO certification, IPI produces one of the widest ranges of spiral welded steel pipes in the region, from 100 mm to 3600 mm in diameter. With a legacy of meeting global standards—including past authorization from the American Petroleum Institute (API)—IPI remains committed to continuous improvement, advanced technology, and supporting the development of world-class infrastructure.

Our Mission

To produce and provide widest range of quality steel pipes using spiral-welded process for potable water lines and irrigation systems; casings; steel pipe piles for port and bridges; structural columns; and conveyance & penstock piping for hydro-power plant in the Philippines.

Our Vision

To be the company of choice in the manufacturing and supply of quality spiral welded steel pipes for local and global market.

How it works

Behind the Process

Our production of spiral-welded steel pipes is driven by precision engineering and strict adherence to international standards. The process begins with the inspection and preparation of steel coils, ensuring material quality and compliance with required specifications.

Using advanced spiral forming technology, coils are continuously shaped and welded through a controlled Submerged Arc Welding (SAW) process, delivering high-strength, uniform weld seams. Key parameters such as heat input, alignment, and weld penetration are closely monitored to ensure structural integrity and consistency across every pipe. 

Post-welding, each pipe undergoes a series of rigorous tests, including non-destructive testing (NDT) such as ultrasonic and radiographic inspection, as well as hydrostatic pressure testing to verify strength and leak resistance.

To enhance durability and corrosion resistance, pipes are treated with high-performance internal and external coating systems. Surface preparation is carried out through abrasive blasting, followed by the application of protective coatings in controlled environments to ensure proper adhesion and long-term performance.

Every stage of our process is aligned with standards such as AWWA and ASTM, supported by a skilled technical team committed to delivering reliable, high-quality piping solutions for critical infrastructure.
