Hello Pipe Enthusiasts!
PT Southeast Asia Pipe Industries (SEAPI) as your steel pipe partner in Southeast Asia presents spiral / Helical Sub-Merge Arc Welding (HSAW) steel pipes with an expanded diameter range from 16 inch to 140 inch. With a proven track record of fabricating extra-long joints for various strategic projects, SEAPI is ready to meet large-scale project demands reliably and on time.
1. Background of the Diameter Range Expansion
The growing complexity of infrastructure and energy demands forces steel-pipe manufacturers to offer more versatile solutions. SEAPI answers this challenge by increasing its HSAW production capacity up to 140″, while also preparing joint lengths tailored to field requirements. This step reinforces SEAPI’s position as your steel pipe partner in Southeast Asia, capable of adapting products to large-scale project specifications.
2. Advantages of Large Diameters & Extra-Long Joints
What makes large diameters and extra-long joints crucial?
- Optimized fluid-flow capacity for oil & gas, drainage, and heavy-industry processes
- Fewer connections, reducing potential leaks and downtime
- Faster installation thanks to minimal welding and handling operations
- Ideal solution for constrained-access sites and long installation routes
As a result, projects move faster, costs stay controlled, and safety improves.
3. Size & Specification Range
SEAPI offers a full range of:
- Diameters: 16″ to 140″
- Wall thicknesses: 6 mm to 25 mm
- Pipe lengths: configurable per project requirement
- Quality control: mill certificates, visual inspection, and ultrasonic testing
Each pipe is manufactured under strict quality supervision in accordance with national and international standards.
4. Field Applications & Case Studies
SEAPI’s spiral / HSAW pipes have been deployed in:
- High-capacity offshore and onshore flowlines
- Foundations for bridges, jetties, and marine structures
- LPG/NGL terminals and energy-distribution facilities
- Geothermal projects and other strategic utilities
- Drinking-water networks (SPAM/PDAM) and raw-water reservoirs
Optimal joint-length designs enable direct delivery with minimal on-site modification.
5. Shipping Facilities & Technical Support
SEAPI operates a dedicated jetty for direct vessel loading. Benefits include:
- Shorter delivery lead times
- Reduced reliance on land transport
- Seamless export across Southeast Asia
Committed as your steel pipe partner in Southeast Asia, SEAPI delivers end-to-end solutions, from technical consultation and specification design to production and shipment, to ensure the success of every project.
