This welded galvanized steel pipe enquiry includes Round Thread Grooved Connection wording in the title. The actual options select thickness and length, leaving the end arrangement unconfirmed. Clarify whether threading, grooving or an explicitly documented combination is proposed before matching the pipe to an installed connection.

Interpret round-thread wording through an end drawing

The table separately records a round section shape, which does not define a thread form. Request the actual end-detail drawing and governing connection specification. Do not infer NPT, a particular round-thread standard or simultaneous grooved/threaded construction from the title alone.

For threading, obtain dimensions, engagement, mating component and sealing procedure. For grooving, request the profile, method, tolerances and compatible coupling, gasket and fasteners. If both features are intended, require their individual allocation and acceptance so the selected assembly can be reviewed.

Complete the welded pipe dimensions and galvanizing

Thickness 1.2 is offered with lengths 12 m, 6 m or 6.4 m. Thickness and outer diameter 150–350 lack stated units. Obtain nominal size, bore, outside diameter and wall with units, and assign ±1% to its intended property and measurement/acceptance basis.

Request the full material designation, exact ASTM document, manufacturing route, condition, traceability and certificates supporting welded manufacture. ERW is not specified here. Define galvanizing coverage, thickness, inspection, end protection and repair, and clarify Slightly Oiled against the finished connection surfaces.

Review actual medium and connection duty

Provide pressure, temperature, medium, concentration where relevant, exposure, cycling and loads. High Pressure and corrosion-resistant wording do not establish numerical limits or universal compatibility. Verify ISO 9001 document scope, then agree support, alignment, testing, inspection, handling, marking, material/dimensional/finish records and quotation scope for the accepted configuration.
