What is a request for quote (RFQ)? And what is the difference between RFQ vs. RFP (request for proposal) and RFI (request for information)? In this article, we explain these terms, which refer to documents issued in different stages of the procurement process in plant project business. RFQ MEANING The term RFQ stands for “request… read more »

Fillet Weld for Socket Fittings

A fillet weld is defined, by the American Welding Society (AWS), as “A weld of approximately triangular cross section joining two surfaces approximately at right angles to each other in a lap joint, T-joint, or corner joint.” This type of welding technique is used to connect socket weld fittings or slip on flanges to pipes…. read more »

Purchase Order and Order Confirmation

A purchase order is a binding document issued by the procurement department for a supplier, stating the terms under which a purchase is made. An order confirmation is a document issued by a seller confirming, to the buyer, the acceptance of a purchase order. Any discrepancy between the purchase order and the order confirmation shall… read more »

Difference Between ODM, OEM and OBM Production Strategies

The terms ODM, OBM, OEM terms designate alternative setups of manufacturing operations. The difference between these production strategies lies in the degree of outsourcing of design, engineering, and manufacturing operations that a brand owner implements (from no outsourcing, i.e. “OBM”, to full outsourcing, i.e. “ODM”).  ODM (Original Design Manufacturing) This is an arrangement by which a manufacturer… read more »

HS Codes for Pipes, Valves, Fittings, Piping

The Harmonized Commodity Description and Coding System (HS) is a recognized standardization system to classify imported/exported products for taxation and statistical reasons. The nomenclature foresees 21 sections, subdivided into 96 chapters and in above 5.000 headings and subheadings (representing individual commodities).  WHAT ARE HS CODES? The HS system defines a serial number for almost any… read more »
