Black & Galvanized ERW Tubes
For general piping and utility requirements where tube series, end condition and galvanised or black finish matter.
Process & Utility Piping
Pipes & Tubes
Flowline brings ERW, seamless and stainless-steel pipe and tube requirements into one clear buying path. Start with material and service, then narrow the enquiry by NB or OD, schedule, wall thickness, length and applicable standard.

Technical guide
Pipe selection starts with size, wall and material.
Compare construction, dimensional references, standards and service context before narrowing the enquiry to the exact pipe or tube requirement.
The catalogue includes black and galvanised ERW steel tubes, MS/SS seamless pipes and stainless-steel tubes. Flowline can therefore organise an enquiry around both general-purpose piping and more specification-led project requirements.
For a clean quotation, share the material, nominal bore or outside diameter, schedule or wall thickness, required length, quantity and applicable standard. If a specification is not final, Flowline can help structure the requirement before commercial confirmation.

Within Pipes & Tubes
Choose the pipe form that matches the service.
ERW, seamless and stainless tube requirements each begin with a different selection path. Start with the construction and then confirm dimensions, grade and end condition.
MS / SS Seamless Pipes
Specified by nominal size, schedule, outside diameter and wall thickness for pressure and process-service enquiries.
Stainless Steel Tubes
Tube requirements can be aligned by outside diameter, wall thickness, finish and weight per metre.
Project Piping
Send the material grade, schedule and service condition when the requirement is tied to a drawing or project specification.
Technical reference
Pipe references worth checking first.
Use these familiar pipe and tube references to align the description, then confirm the final grade, dimensional standard and project requirement with Flowline.
