Common Questions
What types of steel pipes are used for water transmission?
ERW is typically used for smaller diameters, LSAW for higher pressure trunk lines, and HSAW/SSAW for large municipal diameters up to 2,540 mm.
Which API 5L grades are common for water transmission?
Grade B, X42 and X52 are common. X52 PSL2 is frequently specified for municipal transmission mains, while X60/X65 are selected for higher pressure lines.
Do you provide mill test certificates?
Yes. EN 10204 3.1 MTC is standard and 3.2 third-party countersigned certification can be arranged on request.
What standards are typically specified for steel water transmission pipe?
Typical project packages reference API 5L for pipe grade, EN 10224 for aqueous-liquid service in Europe, and AWWA C200 as the base steel water pipe standard, with C205/C210 for linings and coatings.
What coatings and linings are available?
External options include 3LPE (ISO 21809-1) and FBE (ISO 21809-2, -40°C to +95°C continuous). Internal options include cement mortar lining (AWWA C205) and liquid epoxy (AWWA C210), with NSF/ANSI 61 formulations for potable-water projects when required.
Which joint types can be supplied?
Butt-welded ends are the most common for transmission mains. Flanged and mechanical coupling-compatible end preparations can also be supplied where project design requires maintenance access or equipment tie-ins.
Do buried water pipelines require cathodic protection?
Yes. For buried steel lines, external coatings are typically paired with cathodic protection per ISO 15589-1 or project CP specifications to control long-term external corrosion.
How quickly can you deliver from Turkey?
Transit and production timing depend on size and scope. For common regional destinations, practical shipping windows are often competitive after production release.
