Question
What is the mandatory standard for the design of steel pipes in Australia? What are the different parts? What is the most common test to assess the low temperature capability/quality of a steel material? What is the reference? What is the most common material for a stainless steel pipe? As a rule of thumb, what is the minimum temperature (MDMT) for general carbon steel? Which type of fracture mechanism shall be completely eliminated/controlled in the design of pressure piping, Brittle or Ductile?Explanation / Answer
AUSTRALIAN STANDARDS: Grade C250 Pipe is manufactured and tested to comply with the requirements of the following specifications:
AS 1074 - Steel tubes and tubulars for ordinary service
. AS 1163 - Structural steel hollow sections (Grade C250, C250LO).
AS 4792 - Hot-dipped galvanised coating on ferrous hollow sections. Applied by a continuous or a specialised process. LO indicates grades with guaranteed impact performances at 0C.
With impact guaranteed properties, the opportunities for the designer are now enhanced in low temperature service environments under AS 4100.
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 WWP-406c is a federal specification comparable to ASTM A-120 (withdrawn 1988).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. Prescribes minimum requirements for design, manufacture, test, and installations of power piping systems for steam generating plants, central heating 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.
