This carbon steel reducer enquiry carries JIS and polished/painted title references, with NPT in the specification table. Actual variants also offer Stainless Steel. Select the intended material and complete end arrangement before using the surface or low-pressure wording as a supply requirement.
Resolve both ends and the mixed dimensional labels
Five pipe-size options read 10, 12, 14, 50 and 30 mm. Establish what each label measures and specify both connection sizes. Equal table wording does not identify a reducing relationship, transition or orientation; obtain those details on a drawing for the actual reducer.
The table separately records overall length 4 in, height 8 without a unit and hole diameter 0.25 in. Allocate each value to the correct component and confirm the height unit. Agree the dimensional system, wall, tolerances and mating parts rather than automatically converting or combining unrelated entries.
Specify material, NPT detail and surface treatment
Obtain the selected steel grade, governing material document, condition, traceability and certificates. Identify the applicable JIS specification and edition, and verify the listed casting route through production records. Confirm male/female ends, exact NPT designation, engagement, mating connection and sealing requirements.
Polished, Painted and Smooth need an agreed surface schedule with locations, sequence and measurable acceptance. Define any coating specification and delivery protection without assuming a formulation or lifetime. Flexible, corrosion, chemical and UV resistance labels require evidence for the selected material, finish and conditions.
Assess the requested application individually
The qualitative Low Pressure entry and Not Rated class do not provide an accepted operating envelope. Supply actual medium chemistry, pressure, temperature, cycling, exposure and mechanical loads for irrigation, repair, heating, power or construction duty. Confirm joint and component acceptance, then agree alignment, access, inspection, testing, marking and material, process, dimensional and finish documentation.
