  • Conveyance tubes - Inflow™ and Inflow™ Plus

    Inflow™ Plus 235 and Inflow™ Plus 355 are multi-certified, hot-finished HFW (High Frequency Welded) pressure tube for general purpose and industrial conveyance solutions such as HVAC, steam services, petrochemical, process plant and fire protection applications.

    • Premium multi-certified, hot-finished tubes

      Our multi-certified conveyance and pressure tubes provide a simplified solution for diverse application demands.

      Hot-finished for a uniform stress-free tube, with consistent mechanical properties and improved ductility, they are an ideal substitution for comparable hot-finished seamless products.

    • Inline™ and Inline™ Plus - based on EN ISO3183

      We developed our multi-certified Inline and Inline Plus hot-finished pressure tubes to meet the specific needs of industrial end-users.

      Suitable for a wide range of industrial, process and line pipe solutions, Inline and Inline Plus are an ideal substitution for comparable seamless products.

    Key features

    Inflow Plus™ 235 and Inflow Plus™ 355

    • Primary standard EN 10217-2 Grade P235GH and P355NH.
    • Quality designation TC1 supplied as standard.
    • Quality designation TC2 option for sizes ≥OD219.1mm.
    • Multi-certified satisfying the mechanical properties of grades in other industry referenced standards.  e.g. DIN1626 St52.0N/G, DIN1628 St52.4 and DIN17178 WSt E 355.  Please refer to product brochure for full details.
    • Suitable substitute for equivalent hot-finished seamless tube grades e.g. ASTM A106 Grade B, EN10216-2 Grade P25GH & DIN1629 St37.0N, DIN1629 St52.0N, DIN1630 St52.4, & DIN17179 WSt E355.
    • Boiler tube option, delivering additional alignment to generally equivalent industrial standards, available upon request, at time of order.
    • General engineering tube to EN 10219 Grade S235JRH/S275J2H/S355J2H (for sizes greater than, equal to OD219.1mm).
    • Fully weldable.
    • Fully killed steel produced to fine grain practice for enhanced ductility.
    • Full PED compliance being suitable for equipment in PED categories I, II, III or IV, also aligned with AD2000 Merkblatt W4.
    • Suitable for pressure applications and temperature range -20 to +400ºC (except EN 10219).
    • Lower temperature option of -40 ºC available upon request, at time of order (except EN 10219).
    • OD and ID weld beads fully removed.
    • Due to the superior mechanical properties of Inflow™ Plus 355, the same pressure integrity as for Inflow™ Plus 235 can be obtained with thinner walls.  The associated weight savings will enable a reduction in supporting load bearing structures, hangers and brackets etc  Increased wear resistance – providing improved service life for applications where this is a consideration.
    • Backed up by technical experts who can offer advice on applications and product suitability.
    • Fully technically supported with a range of available product brochures.
    • Certified to BES 6001 Responsible Sourcing standard.
    • Supplied with 3.1 inspection certification to EN10204.

    Inflow CDC

    • Primary standard EN 10217-1 Grade P235TR1.
    • Cold-formed Dual Certified (CDC) HFI pressure and general engineering tube
    • PED (2014/68/EU, formerly 97/23/EC) - Pressure Equipment Directive Test Category I or SEP (Sound Engineering Practice) applications only
    • General engineering tube to EN 10219 Grade S235
    • Quality designation JRH – room temperature impact properties guaranteed
    • Generally equivalent to BS3601
    • ID weld bead treated
    • Backed up by technical experts who can offer advice on applications and product suitability.
    • Certified to BES 6001 Responsible Sourcing standard.
    • Supplied with 2.2 test report to EN10204.
