Piping Design for a Compressed Air System

Complete Design files and calculation Files including AutoCAD files for the project are expected. w). Piping and Auxiliaries Requirement – (i) Length - 800 mtrs (ii) Pipe: ASTM A 312 standard TP 316L Stainless steel seamless pipe (iii) MoC: SS 304 (iv) Pipe Size: 12mm (OD) x 2mm (Thickness) = 8mm (ID) (v) Working Pressure – upto 500 Bar (vi) Temperature - 100 Deg C (vii) Certification - ASME / ANSI B1.20.1 or equivalent standards x). HP Air Fittings: All associated pipe fittings utilized in HP air pipes usage are to be sourced from renowned firms in the business of manufacturing high end high pressure pipes and fittings. The fittings are to be to be compatible to the piping of SS 316L grade and capable for working pressure of 450 Bar and a temperature of 100°C and to be manufactured from applicable ASTM bar stock specifications or equivalent bar stock specifications. The fittings as far as possible are to be standard sizes and to adhere to relevant ASME / ANSI standards for the above grade and working parameters. The pipe fitting threads are to be NPT and to exceed the requirement of ASME / ANSI B1.20.1 or equivalent standards. Certification is to be undertaken as per EN 10204/3.1 or equivalent standard. The source of items procurement by the OEM is to be intimated in the Technical bid for acceptance and concurrence of the Buyer. y). Design of Pipe sizes from Compressor to Bottles and from Building to Jetty Cope points: Design calculation for sizes for piping from Compressor to Bottles may be undertaken in a scenario such that each Bottle is being filled simultaneously from 02 compressors. Design calculation for sizes for piping from Air Bottles till the jetty cope point may be undertaken in a scenario such that the jetty cope point receives 410 Bar HP air with 180m3 /hr flow rate at 2 points and 250 Bar HP air at 2 other points. A general arrangement sketch drawing of the layout of compressors and Bottles along with piping sizes are to be submitted during the Technical Bid stage. Details of the piping schedule calculations is to be worked out and submitted during the Technical Bid stage. The design may be as per AS 4041-2006 „Pressure Piping‟ or such equivalent standards pertaining to the subject. The HP Air Pipes and fittings mentioned in above paragraphs are to be sourced indigenously as per the required standards and stocks and supplied with all certifications mentioned in above paragraphs and in subsequent paragraph. z). Hydrostatic/ Leak Proof Test of pipes to be undertaken at Factory premises and after Installation at site. aa). Cope points: 04 cope points with each point having 2 delivery ports of 400Bar and 250Bar each with pressure gauges.
