OFF RANCHI PROCESS & PIPING DESIGN SECTION NEW DELHI STANDARD SPECIFICATION SCRAPPER TRAP TECHNICAL SPECIFICATION NO. : MEC/S/05/62/007 REV-1 Page 3 of 10 3.0 MATERIALS D:\Technical Specifications & Standards\007 - Scrapper Trap - TS.doc m) SSPC-VIS-1 : Steel Structure Painting Council In case of conflict between the requirements of this specification and the requirements of above referred documents, the requirements of this specification shall govern. 3.1 Materials and thicknesses of main components used in manufacture of traps shall be indicated by Manufacturer and shall be suitable for service conditions indicated in the data sheets and annexures. These shall be subject to approval by purchaser. The steel used shall have a minimum SMYS of 35,000 psi. 3.2 Fully killed carbon steel shall be used. 3.3 Material of the ends to be field welded by purchaser shall have carbon equivalent less than or equal to 0.45 based on check analysis, for each heat of steel, calculated according to the following formula. Mn Cr + Mo + V Ni + Cu CE = C + -------- + --------------------- + --------------- 6 5 15 3.4 For Scraper Traps, specified to be used for Gas service or High Vapour Pressure (HVP) liquid service, Charpy V-notch test shall be conducted at 0°C for each heat of steel used in the manufacture of pressure containing parts of the traps. Test procedure shall conform to ASTM A-370. The Charpy V-notch test specimens shall be taken in the direction of principal grain flow and notched perpendicular to the original surface of the plate or forging. The minimum average absorbed impact energy values of three full sized specimens shall be as under, unless otherwise indicated in the Data sheets :- Diameter Base Metal Weld Metal and HAZ (inches) (Joules) (Joules) For all size 27 27 The minimum impact energy value of any one specimen of the three specimens analysed as above, shall not be less than 80% of the above mentioned average values. For scrapper Traps, specified to be used for other hydrocarbon service, the Charpy Vnotch test requirements as stated above are not applicable.
