Dimensions and Tolerances	Outer Diameter and Wall Thickness Deviations	Depending on the processing methods, the allowable deviations for cold-rolled tubes and hot-extruded tubes are different to ensure product quality.
Chemical Composition Requirements	Correspondence between Brand and Content	Detailed list of chemical composition ranges for each alloy brand, such as the mass fraction of elements such as Ni, Cu, and Cr.
Mechanical performance standards	Tensile strength and elongation	Specific numerical requirements for Rm, Rpo.2 and A are specified according to different grades and delivery conditions.
Non-destructive testing	Ultrasonic and eddy current testing	GB/T 5777 and GB/T 7735 standards are adopted to ensure effective identification of internal defects of pipes.

Implementation suggestions

Select the appropriate alloy grade:According to the corrosiveness and mechanical load requirements of the use environment, corrosion-resistant alloy grades with different chemical compositions and mechanical properties are selected.

Pay attention to the delivery status:Clarify whether post-processing such as heat treatment, pickling or polishing is required, which affects the performance and convenience of use of the material.

Strict inspection process:According to the chemical composition analysis, mechanical properties test and non-destructive testing methods specified in the standard, the acceptance is carried out to ensure product quality.
