Offshore and marine materials
Offshore units built or converted in Singapore use super duplex for seawater cooling, firewater ring mains and ballast systems, duplex and 316L for utilities, and carbon steel for process and structural piping. Marine classification societies and project specifications often require specific testing, marking and documentation, and material may need to be certified for the classification society named in the order. We supply complete material packages – pipe, fittings, flanges and bolting in the same grade – with matching mill certification.
Standards, specifications and sour service
We review the specification named in each enquiry – the owner's or EPC contractor's material requirements, supplementary testing, marking and documentation – and confirm which requirements can be met before quoting. Material for sour service can be supplied to NACE MR0175 / ISO 15156 on request. Our company is certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018, and mill test certificates (MTC) are supplied with all material.
Shipping to Singapore
Shipments leave from Nhava Sheva (JNPT) near Mumbai for Singapore (Pasir Panjang and Tuas), and urgent consignments can go by air freight to Singapore Changi. We quote on EXW, FOB, CFR and CIF terms, and transit time is confirmed with each quotation. Material is packed for sea freight in bundles, wooden boxes and crates with ISPM 15 treated wood, and each package is marked to the buyer's instructions. Documents include the commercial invoice, packing list, certificate of origin, bill of lading and MTC, with attestation or legalisation where the buyer requires it. Third-party inspection by the buyer's nominated agency can be arranged before dispatch.
Regional supply
Many Singapore-based stockists and traders supply projects across Southeast Asia, and material can be shipped to Singapore for consolidation or direct to the end project, with documents prepared accordingly.
