SNI 39:2024, as specified in the project documents
Lead time
15 days from confirmation to completion of supply
Status
Supply complete, project execution ongoing (2026)
Scope
A Ø2840 mm pipe at 20 mm wall is a heavy section — roughly 1.4 tonnes per metre, so every handling step from the forming station to the quay has to be planned around crane capacity, not around the pipe. The order was produced as one continuous campaign on a single size, which is what made a 15-day delivery realistic rather than optimistic.
Heavy-wall large-diameter pipe after blasting, on the coating line
What made 15 days possible
Single-size campaign — no changeover between diameters, one set of forming and welding parameters throughout.
12 m lengths — fewer field girth welds per kilometre, lower installation cost for the contractor.
Q235B plate stock — heavy-gauge plate held in inventory before the order was confirmed.
In-line inspection — UT of the spiral seam and dimensional check at the end of the line, no batch held back for later testing.
Standard note
Supply followed the SNI 39:2024 requirements named in the project documentation, with mill test certificates issued per heat number and hydrostatic testing before coating.
