Dimensional Standards of EN 10216-3 Grade P355NL2


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 Sizes 1/8 inch through 24 inch.WWP-406c is a federal specification comparable to ASTM A-120 (withdrawn 1988).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.

  • M-111 covers black and galvanized welded and seamless pipe intended for coiling, bending, flanging, and other special purposes and is suitable for welding. Purpose for which pipe is intended should be stated on orders. M-111 is comparable in most requirements to ASTM A-53.
  • M-130 covers black and galvanized welded and seamless pipe for ordinary uses in steam, water, gas, and air lines. Sizes 1/8 inch through 12 inch. Pipe to this specification is not intended for close coiling, bending, or high temperature service. M-130 is comparable in most requirements to ASTM A-120.

EN 10216-3 Grade P355NL2 specification covers Alloy fine grain steel, pressure purposes. Pipe will be supplied in 5-7 metre random lengths with butt-weld ends and varnished to avoid oxidation of the steel when in storage. All pipes are fully certified and traceable with heat numbers hard stamped onto each random length. Ferro Pipe can supply cut lengths; long pieces and even bore from forged, machined bar to satisfy your urgent demand.
