Requirements for the quality and certifications of pipeline and fitting procurement
Thread Content
Previously, the purchase order only specified the product name, specifications and model, material, and standards (such as GB/T 12459 for pipe fittings). I believe a quality certificate is something that all materials must have when leaving the factory, so no requirement was set for it. The technical document does not require CCS certification, so there is also no requirement to provide a CCS certificate. During the subsequent bidding negotiations, the quotes submitted by the suppliers were very low, while the quotes given by the steel mills were high; they claimed that the prices offered by the suppliers were even higher than the cost of their raw materials. Where is the price difference? Should the requirements for quality certificates be included in the technical specifications of the material order? What other requirements should generally be included? If the fittings supplied by the vendor do not have the furnace batch number from the original steel manufacturer, it is impossible to ensure the traceability of the material; what problems might arise as a result? Thank you.
It must be written in there; the purchase order needs to be as detailed as possible to prevent suppliers from taking advantage of loopholes. The character \"high\" at the end of the third line seems to be a mistake – it should probably be \"low\". The supplier’s channels are rather complex, but in any case, the product costs less than the raw materials, which is definitely a problem. You must provide the product’s model, specifications, dimensions, compliance with standards, as well as various certificates and third-party inspection and certification documents – it’s best to have all of them. Even if it means paying a bit more in fees, it’s still better than buying a pile of useless junk!
For materials whose application context is important, it is recommended to purchase them directly from the manufacturer; the sourcing of materials through intermediaries is too complex and difficult to control. Regardless of where they are purchased, it is essential to conduct a proper evaluation of the suppliers.
From a technical requirements perspective, what needs to be added additionally? Taking pipe fittings as an example again, the standard used is GB/T 12459; this standard specifies the quality inspection requirements and mandates that a quality certificate be provided. Therefore, when the goods arrive, the quality control department will definitely carry out inspection in accordance with these standards, and all these intermediaries are capable of doing so. If the quality certificates required by the standards cannot ensure that suppliers do not cut corners on quality, what else can be demanded? You can’t just say that because your price is low and cheap goods aren’t of good quality, so you won’t buy from you As a technical specialist, all I can do is set technical requirements as thresholds. Specific price comparison and selection are the responsibility of the procurement department.
When purchasing pipe fittings in bulk, it’s better to choose the manufacturer directly. Many intermediaries or retail stores have a low standard of quality; they’re only interested in getting the order, and as a result they end up supplying you with products that look similar but have poor material quality and inferior standards
In any case, it’s best to write it down clearly. One also needs to have testing methods, as many quality certificates are fake!
