For fluid-conveying pipes, the primary focus is on hydrostatic testing as well as flattening and flaring performance; boiler pipes require additional attention regarding high-temperature performance and non-destructive testing; meanwhile, precision pipes prioritize inner diameter tolerances, wall thickness uniformity, and internal surface roughness.

Therefore, when purchasing seamless pipes, it is advisable to first clarify the applicable standards and operating conditions before discussing specifications and pricing. Pipes with identical outer diameters and wall thicknesses can vary significantly in cost due to differences in standards and inspection requirements; relying solely on a "price per ton" comparison can easily lead to misleading conclusions.
