3.1 Inspection Certificate

Cert. issued and signed by manufacturer’s representative, who must be independent of the manufacturing department. Eg Inspection department or test house manager/supervisor.

3.2 Inspection Certificate

Cert. issued by both manufacturer’s representative and an independent inspector appointed either by the customer (cf withdrawn 3.1C) or an inspector designated by official regulations (cf withdrawn 3.1A). ie 3.2 now covers scope of both 3.1A and 3.1C of 1991 edition. This cover what is often referred to as ‘outside inspection’

Annealing

Annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable . The process requires heating material to a required temperature under various environment (for some alloys) and then allowing it to cool down according to process specified .

AOD Process

Argon Oxygen Decarburization (AOD) is used during the refining process to produce steel with low carbon properties and low silicon levels, while creating a metal more weldable and more corrosion and heat resistant. It brings the tightest chemistry control to deliver the highest levels of metal purity.

The process injects oxygen and inert gas (argon or nitrogen) through submerged tuyeres and additional oxygen is blown through a top lance. The AOD process is suitable for production of stainless steel and other high-grade alloys because dilution with argon/nitrogen minimizes unwanted chromium oxidation.

ASTM Standards

ASTM International creates standards for a multitude of materials, products, test methods, and systems for a variety of industries.

Bars

A solid steel product, commonly in flat, square, round or hexagonal shapes. They are further machined , forged , finished to make different products . This a base product used by various industries all over the globe.

Beveling or Bevelled Ends

Pipe beveling is the process where an angle is formed between the edge of the end of a pipe or tube . This abbreviated as BE for projects or orders . This process is done to make welding of the pipe easier and better .

Bill of lading

A bill of lading is a legal document between a shipper and a carrier that details the type, quantity and destination of the goods being carried. The bill of lading also serves as a shipment receipt when the carrier delivers the goods at the predetermined destination.

Billet

A semi-finished steel product with a square cross section up to 155mm x 155mm. This product is either rolled or continuously cast and is then transformed by rolling to obtain finished products like wire rod, merchant bars and other sections. The range of semi-finished products above 155 mm x 155 mm are called blooms.

Pipe

A pipe is a tubular section or hollow cylinder .Dimensions are generally specified by a nominal diameter as per ANSI B36.10M & ASME B36.19M with a constant outside diameter (OD) and a schedule that defines the thickness in chart here Nominal Pipe Size . Pipe come in two types , Seamless and Welded

Pipe Fittings

Piercing

Sandblasting

Seamless Pipe / Tube

Seamless Pipe / Tube is manufactured by extruding the metal either by Hot Working or Cold Working to the desired length; seamless pipe does not have any joint (seam) in its cross-section through-out its length.

Welded Pipe / Tube

Welded Pipe / Tube are made by ERW (Electro Resistance Weld) or EFW (Electro Fusion Weld) manufacturing process, welded pipes are formed by hot or cold rolling plate and welding the seam.
