Pre-Shipment Inspection for Pipe and Fittings: A 40-Point Checklist
Here is a fact most buyers never use against their supplier: the pipe product standard already contains an inspection plan. GB/T 18742.2-2017, the PP-R pipe part of China’s adoption of ISO 15874, mandates sampling inspection by GB/T 2828.1 at AQL 4.0 for appearance and dimensions.

Can You Use PEX-B Fittings on PEX-A Pipe? The ASTM Answer
You can put a PEX-B crimp or clamp fitting on PEX-A pipe. It is a standard-compliant joint, not a workaround, and the reason is that the letters A, B and C do not describe three different pipe sizes. They describe three ways of crosslinking the same polyethylene, and all three land in the same dimensional

Incoterms and Packaging for Pipe Imports: Cutting Damage, Demurrage and Cost
Importing pipe incoterms packaging decisions usually get made in the wrong order.

1/2 PEX Pipe Fittings: Sizes, Standards, and Specs
1/2 pex pipe fittings sit at the center of most residential fitting orders, and the size trips up more buyers than any other.
