Dimensional Standards

Dimensional Standards of EN 10083-2 Grade C25

FEDERAL

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 Sizes 1/8 inch through 24 inch.WWP-406c is a federal specification comparable to ASTM A-120 (withdrawn 1988).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

A.W.W.A.

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.

ASME

B31.1 Code for pressure piping.plants, and industrial plants.
B31.2 Fuel Gas Piping.
B31.3 Petroleum Refinery Piping.
B31.4 Liquid PetroleumTransportation Piping Systems.
B31.5 Refrigeration Piping.
B31.7 Nuclear Power Piping
B31.8 GasTransmission and Distributing Piping Systems. Covers design, fabrication, installation, inspection, testing, and the safety aspects of operation and maintenance of gas transmission and distribution systems.

ANSI (ASME)

B36.10 American Standard for Wrought-Steel and Wrought-Iron pipe. Designates dimensions, weights, and schedule numbers for welded and seamless pipe. Schedules 10 through Schedules Double Extra Heavy (DXH/XXH).
B36.19 American Standard for Stainless Steel Pipe. Designates dimensions, weights, and schedule numbers for welded and seamless Stainless Steel Pipe, Schedules 5 through Schedules 80.

A.A.R.

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.

Product Description

EN 10083-2 Grade C25 European standard covers quenching and tempering And Technical delivery conditions for non alloy steels. 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. Trio Steel can supply cut lengths; long pieces and even bore from forged, machined bar to satisfy your urgent demand.
Trio Steel is considered as the most Reliable EN 10083-2 Grade C25 Pipes and Tubes Supplier from India.
