API Line Pipe Plant for Integrators — Scope and Third-Party Witness

Spiral welded pipe mills in the Tengtian workshop

API Line Pipe Plant

API Line Pipe Mill

API line pipe plants for integrators. The line is a high-frequency mill extended with medium-frequency annealing, straightening, end facing, hydrostatic testing, ultrasonic and eddy-current inspection, covering outside diameter 114 to 508 mm with wall 6 to 24 mm by step.

Size Window, Inspection Chain and Certification

  1. Size window: OD 114–508 mm, wall 6–24 mm by step; steps API 219 / 406 / 426 / 508.
  2. Inspection chain: annealing → straightening → end facing → hydrostatic → UT → ECT.
  3. Factory certification status: confirmed on enquiry.

Programme Scope and Who It Is For

The buyers are line pipe plants producing API 5L pipe for oil and gas transmission, where weld performance and the compliance inspection chain are described as the order threshold rather than a quality preference. Our users are the plant’s process, quality and NDT personnel; beneficiaries are pipeline EPC contractors and energy infrastructure owners.

The switching trigger is entering a standards market — API 5L or GOST — which requires compliant equipment outright.

Configuration Tiers and What Each Tier Includes

What separates one configuration from another here is the inspection train: whether the line carries in-line NDT and post-processing at all. An ordinary welded line does not; an API line does. The NDT and hydrostatic units count as core equipment, because together they are the API 5L compliance chain.

Turnkey line or single unit, with pricing tiered by configuration reflecting scope.

Frequently Asked Questions

What does the dealer/partner programme include?

For integrators the content is scope, inspection chain and standards rather than a partner agreement: turnkey or single-unit supply, the full six-station post-weld and inspection train, 50 to 90 day delivery, and installation and commissioning included.

What is the minimum order and how are territories allocated?

There is no minimum order quantity and no territory allocation rule for this family. The only MOQ we apply is on the automatic spray coating line — about one set, bundled with a main line — and it does not extend to other equipment.

What are typical lead times and payment terms?

Delivery is 50 to 90 days with plant-level customisation scheduled from our own manufacturing base. Payment is flexible: a thirty per cent deposit against seventy per cent before shipment, with third-party escrow and staged payment available and multiple trade terms supported.

Minimum Order and Stock Position

There is no minimum order quantity, no stock-holding requirement and no territory rule for this family. What we offer instead is the commercial frame those terms would sit inside: tiered configuration giving resale margin, 50 to 90 day delivery, and

Marketing and Technical Support Provided

Technical support covers a single point of contact and online support, both round-the-clock, engineers dispatched on site, and installation and commissioning included in the after-sales scope. Marketing support — co-branded material, lead sharing, demonstration equipment — is agreed case by case.

On-time delivery is the criterion agents actually judge on, because their own downstream customers depend on it.
