Cold finish seamless tubes and pipes in straight, corrugated, U-bend and coil form, plus a dedicated high purity range — supplied to ASTM, ASME, EN and DIN standards.
Seamless stainless tubes are formed from a solid billet, pierced or extruded and then hot- or cold-rolled so the tube carries no welded seam along its length, resulting in a fully homogeneous wall.
Because there is no weld line, seamless products generally offer higher pressure ratings, better mechanical strength and superior resistance to pitting and crevice corrosion in high-pressure, high-temperature and critical service lines.
Round hollow sections with no longitudinal weld, supplied in straight lengths for piping, heat exchanger, hydraulic and instrumentation service. Tubes are specified by OD and wall thickness; pipes by nominal bore and schedule.
Rigid stainless steel tubes with engineered helical indentations that force boundary-layer turbulence, increasing the heat transfer coefficient by 2 to 3 times over bare tube. Designed for shell-and-tube and tube-in-tube exchangers in food, dairy, chemical and HVAC service.
Tubing formed into a U-shape by precision cold bending for heat exchangers, boilers and instrumentation systems. Seamless construction ensures pressure resistance and leak prevention across petrochemical, nuclear, machine building and boiler applications. Finishes: annealed, pickled, polished or bright annealed.

Continuous lengths of seamless tubing wound into compact coils for instrumentation, hydraulic systems, chemical processing and oil & gas service where space saving and high pressure resistance matter. Custom annealing keeps the coil flexible during uncoiling.
Small-diameter, high-precision cold-drawn tube for pressure, vacuum and signal lines — transmitters, flow meters, analyzers, control panels and safety circuits. Very tight OD and wall tolerances ensure leak-free connections with compression fittings; bright annealed or polished bore eases cleaning.
The primary heat transfer element in shell-and-tube exchangers, condensers and reboilers. Cold-drawn seamless tube with uniform wall, smooth bore and bright annealed or pickled–passivated finish to resist fouling and withstand cyclic thermal stress. Common sizes: 19 × 2 mm, 25 × 2.5 mm, 38 × 2.5 mm.
Tubing for semiconductor, bioprocessing and hygienic service — electropolished internal surfaces, controlled sulphur chemistry and cleanroom packaging.
For transporting ultra-high-purity gases, chemicals and fluids where even trace contamination must be eliminated.
Electrochemical finishing removes 10–15 µm of material, eliminating microscopic imperfections, burrs and contaminants.
Manufactured to the ASME BPE standard for biopharmaceutical, pharmaceutical and biotechnology systems.
UHP tubing to SEMI standards for ultra-pure gas and chemical delivery in wafer fabrication — etching, lithography and other critical processes.
Polished tubing with smooth, crevice-free interiors that prevent bacterial buildup and support clean-in-place routines.
Chemical treatment removes free iron introduced by machining and grinding, and strengthens the natural chromium oxide layer.
Send grade, OD, wall, length, standard and finish — we will revert with feasibility and lead time.
