All tubes are supplied with clean, square cut ends.Deburring and/or chamfering can be carried out on request.
Tubes are supplied normally without anti-corrosive treatment, but anti-corrosive treatment is available and is carried out on request.
Tubes are bundled as standard, with steel straps into hexagonal bundles with one end flush.Length sorting can be carried out on request. Tubes can also be bundled in multiples. Bundle weights are adjusted as requested by the customer. Each bundle contains tubes from a single cast/heat only.
Each tube is marked with tube type, heat number, steel grade and size. Information is repeated along the whole length of the tube. Other markings, such as stamping, can be made on request. Bundles are also labeled with a tag having info both alphanumeric and by bar code.
Material delivered direct from our mill is labeled in accordance with automotive standard, ie with both alphanumeric and bar code information. Customer specific data can be added on request.
WWP-404c is similar to ASTM A-53 except that Government inspection and continuous identification marking of electric weld and seamless is mandatory. It covers black and galvanized welded and seamless pipe for flanging, bending, and coiling and for use with fresh water, oil, steam, air, and gas on shore plus a limited number of shipboard uses. Sizes 1/8 inch through 24 inch.WWP-406c is a federal specification comparable to ASTM A-120 (withdrawn 1988). Mills can certify that A-120 pipe in a distributor-s stock meets all the requirements of WWP-406c.
C-200 covers black welded and seamless pipe intended for the conveyance of water in sizes 6 inch and larger. Specification prescribes hydrostatic test pressures for sizes of pipe covered. Tensile, flattening, and bending tests are required.
