Stainless & structural
steel fabricators

K999 is a stainless steel fabricator in Rayong, Thailand, producing tanks, pressure vessels, chutes and hoppers, pipe spools and structural items in SS316L, SS304L, SS310, Duplex and Super Duplex. Three segregated workshops keep stainless work away from carbon steel, and a 6,000 W fiber laser cuts stainless plate up to 16 mm thick.

Yes. As a structural steel fabricator we produce around 10,000 tonnes a year of members, trusses, modules and conveyor structures to AS/NZS grades, and ship them to Australian mining and processing projects from Rayong. Local steel is available in JIS, AS, BS, EN and ASTM grades to suit the specification.

Steel fabrication Australia projects run from our 33,000 m² Rayong yard and 80,000 m² Sattahip assembly yard, with port access at Sattahip, Map Ta Phut and Laem Chabang. We handle detailing, fabrication, blasting, coating, inspection and documentation, then ship FOB or CIF to the Australian port you nominate.

Pressure vessels in Australia are built to ASME Section VIII Div. 1 under our ASME “U” stamp No. 43,462, or to AS/NZS and BS where the client specifies. We produce separators, air receivers, water drums, waste heat recovery boilers, reformers and pig launchers with design calculations and full documentation.

As a steel tanks fabricator we build carbon and stainless tanks for fuel, biofuel, chemicals, water and food processing, designed in house with our “E Tank” programme to API, ASME, BS and AS/NZS. Offshore tanks are shipped inside transport frames to prevent leakage or spillage.

Yes. Mining equipment and conveyors are a core product, including chutes, hoppers, ore bins, transfer towers, overland conveyor structures and wear liners in Bisalloy or Hardox. Around 90% of that output is supplied to overseas mining companies, predominantly in Australia.

We fabricate pig launchers and receivers complete with barrel, reduction, quick opening closure, nozzles, supports and skid, welded to ASME under our “U” stamp. Each unit is hydro tested, blasted, coated and documented before dispatch.

Chutes and hoppers are fabricated in carbon or stainless steel, then lined with Bisalloy, Hardox or a client specified wear plate, with hardfacing or rubber lining where impact and abrasion demand it. Liner fitting and curing are completed in our workshops, so site work is limited to installation.

Stainless steel pipe welding is carried out by welders qualified to ASME IX and client codes, with procedures covering GTAW and GTAW/SMAW on SS304L, SS316L, Duplex and Super Duplex. Welds are inspected by visual, penetrant, radiography or hydrostatic test as the inspection and test plan requires.

Pipe spooling Australia packages are detailed in 3D AutoCAD, cut, fitted, welded, X rayed, blasted and coated in Rayong at up to 3,000 diameter inches per shift, then shipped as numbered spools ready for site erection. Piping is built to ASME B31.1 or B31.3, with AS/NZS accepted where specified.
