From carbon to super duplex, from copper to titanium.
What follows is an indicative map of the families we move most frequently, not a closed catalog. For off-list grades contact us: either we handle it within the network, or we know who can.
Seamless tubes
Seamless tubes for heat exchangers, condensers and pressure applications. OD from ~3 mm to ~250 mm. Length up to 30 m (carbon) or 22 m (stainless). Sub-spec for heat exchangers with guarantee of minimum wall thickness below fins. Korean and Chinese origin depending on the grade.
Carbon: A179 · A192 · A210 · A106 · A334 LT (1/3/6/7/8/9). Stainless: TP304/304L · TP316/316L · TP321/321H · TP347 · TP317L. Low alloy: T11 · T22 · T91. Nickel: Inconel 625 · Monel · Hastelloy. Titanium: Gr.1/2/7/9/12.
Fin tubes
Finned tubes for air coolers and economizers, Korean production as reference. Types: L-fin wrap-on, G-fin embedded (groove depth 0.25-0.40 mm), LL-fin overlapped footed, extruded fin, low fin, oval, spiral, I-fin, inner-groove. Fin material: aluminum strip 99.7% nominal / 99.5% minimum. Fin pull-off test on three samples per batch.
Tube: all carbon and stainless grades. Fin: Al 1050/1060.
Forgings
Open-die forging up to ~250 mm thickness and diameters beyond 2 m, Chinese production as reference. Tube sheets, rings, flanges, clad discs, forged heads, valves, shafts, blocks, special geometries. In-house heat treatment (normalization, solution annealing, quench+temper). 100% UT NDT per specification.
ASME: SA-105 · SA-266 Gr.2 · SA-350 LF2 · SA-508 Gr.3 Cl.1 · SA-694 F52/F65 · SA-182 F5/F9/F11/F22/F22V/F91/F92 · SA-182 austenitic F304-F347 · SA-182 F6NM/F6A · SA-182 F51/F53/F55/F60 · SB-564 N06625 / N04400 / N08800 / N08825 / N10276. EN: equivalents EN10250 / EN10222 / EN10084.
Plates and clad
Carbon and stainless steel plates for shells and heads. Clad products type A266+B443 or A516 Gr.70+B443 for corrosive service: the carbon-steel substrate provides structural strength, the nickel alloy provides chemical resistance.
Carbon: A516 Gr.70 · A285. Stainless: A240 304/316/321. Clad: substrate A266 Gr.2 / A516 Gr.70 + cladding SB-443 N06625.
