Frequently Asked Questions

Technical Q&A for Indonesian Procurement & Engineering Teams

Expert responses addressing standard specifications, quality control, logistics, and order customization.

What is the structural difference between ERW, LSAW, and SSAW welded steel pipes?
ERW (Electric Resistance Welded) pipes are formed by cold-rolling steel strip into a cylinder and joining the edges using high-frequency electrical current without filler metal (typically available in diameters up to 24 inches).

LSAW (Longitudinal Submerged Arc Welded) pipes utilize heavy steel plates bent via JCOE or O-forming machines and welded longitudinally with double-sided submerged arc welding. LSAW is ideal for high-pressure oil/gas trunklines and thick-wall applications.

SSAW (Spiral Submerged Arc Welded) pipes are produced by ribbon-forming hot-rolled steel coils into a spiral shape, welding the seam continuously inside and outside. SSAW allows large diameter production (up to 120 inches) at competitive costs for water mains and piling.
How do your steel pipes comply with API 5L PSL1 and PSL2 requirements?
Our manufacturing plant holds official API 5L certification. For PSL1, we satisfy mandatory chemistry, tensile, and pressure test requirements. For PSL2, we execute strict carbon equivalent (CEQ) controls, mandatory Charpy V-notch impact testing across weld and heat-affected zones (HAZ), non-destructive testing (NDT), and fracture toughness validation required for critical oil and gas service.
Can you supply 3LPE coated welded steel pipes directly to Indonesian ports?
Yes. We feature an integrated 3LPE/3LPP/FBE coating plant on-site. Pipes are coated in strict compliance with DIN 30670 / ISO 21809-1 specifications. We package pipes with protective end caps, bevel protectors, and wooden cradles to prevent damage during ocean freight to Jakarta (Tanjung Priok), Surabaya, Batam, or Morowali.
What are the lead times and minimum order quantities (MOQ) for custom pipe orders?
Standard stocked sizes (ERW 2" - 12") can ship within 7 to 10 days. Customized LSAW or SSAW orders with specialized wall thickness, bevel angles, or 3LPE coatings typical production cycles range from 20 to 35 days depending on tonnage. Our flexible production lines accommodate both project-based small batch runs and high-volume pipeline orders.
How do you support local TKDN requirements for Indonesian government projects?
While foreign-manufactured raw pipes carry zero base TKDN value, we partner with Indonesian EPC contractors by supplying semi-fabricated line pipes, custom-bevelled ends, matching weld fittings, and providing technical support for local assembly, coating, and spool fabrication in Indonesian yards to maximize overall project TKDN compliance.
What Quality Assurance testing is performed prior to export dispatch?
Every pipe undergoes 100% hydro-testing (up to 50 MPa pressure holding for 10+ seconds), online Ultrasonic Seam Testing, X-Ray Radiographic Inspection on weld intersections, Dimensional Bevel Checking, Positive Material Identification (PMI), and wall thickness measurement before issuance of MTC EN 10204 3.1.
