This Class 150 NPT socket steel pipe enquiry concerns construction applications. The table identifies galvanized carbon steel, while the title adds flexible, chemical-resistant and corrosion-resistant wording. Confirm the actual pipe and connection construction before assigning a rating or treating those descriptions as proven performance.
Describe the NPT socket ends and intended movement
Obtain the end-detail drawing, thread dimensions, mating component, engagement and sealing procedure. Clarify how socket wording applies to the proposed connection and agree joint inspection. The catalogue does not provide enough detail to establish a complete installed assembly from the title alone.
Ask what Flexible means for this item: installation adjustment, permitted joint movement or another documented feature. Request allowable movement, loads and conditions where relevant. Do not assume a flexible pipe body or a particular connection capability without accepted construction and performance records.
Complete the galvanized pipe dimensions and grade
Thickness 1.2 is paired with lengths 12 m, 6 m and 6.4 m. Its unit is missing, as is the unit for outer diameter 150–350. Specify actual nominal size, bore, wall and units; clarify the property covered by ±10% and agree dimensional acceptance.
Request the full steel designation, governing ASTM document, manufacturing route, condition, traceability and material certificates. API/EMT/Thick Wall labels remain generic references. Define galvanizing coverage, thickness, inspection and finish acceptance, including how Slightly Oiled applies to the final product and connection surfaces.
Set Class 150 construction and chemical limits
Confirm the rating specification and applicable material, temperature and configuration. Provide actual medium, concentration, exposure, pressure, cycling and loads for compatibility approval. Verify CE/ISO 9001 document scope, then agree installation support, thread/joint inspection, marking, handling, records and quotation scope.
