Piping, Valves, and Fittings Sample Clauses

Piping, Valves, and Fittings. All materials for hydrogen peroxide shall be stainless steel with Teflon or viton seals and O-rings. Vented ball valves are required to prevent internal pressure buildup, and pressure relief valves shall be anywhere chemical could be trapped. Each system is designed with antisiphon, check valves, calibration cylinders and a pressure gauge. All samples collected for analysis will be grab samples or from approved auto sampling equipment. Acceptable methods of analysis are listed below: Liquid (grab) samples Procedure Total sulfide Std. Methods 4500-S2- D. Methylene Blue (Xxxxxxx drop count kit) Dissolved sulfide Ditto, using pre-flocculation to remove insoluble sulfides pH Combination glass electrode Temperature NIST calibrated thermometer Residual H2O2 DPD redox test strips (e.g., EM Quant) Vapor samples (continuous datalogging) H2S, ppm App-Tek OdaLog and RTX units or equal (monitor / data logger)

Piping, Valves, and Fittings. The following design work is envisaged for the system piping, valves and fittings making up the Works:  All pipes and equipment are rated to withstand the maximum calculated system transient pressures, and required pressure tests, but shall not be rated for less than 1000 KPa.  Supporting of pipes on the entire piping system is re-evaluated and a design is provided as part of the detailed layout design.  HDPE above ground piping applications, pipe supports is designed such that the supports provide adequate pipeline support, accommodate thermal expansion and contraction movement, and provide support spacing that limits vertical deflection between supports.  The support is gently support at least the bottom 120° of the pipe, and be at least 1/2 pipe diameter wide.  Edges are rounded or rolled to prevent cutting into the pipe. In addition to designing a suitable piping and support system, the following must be adhered to:  The existing settling tanks feed and return PVC pipes are replaced with UV protected HDPE pipes, dimensions on drawing 0.48/4589.  Sand filter piping – the existing section from the filter feed pumps to the filters is replaced with new UV protected HDPE piping.  The tank overflow pipe is replaced by a UV protected HDPE pipe.  Replacement of steel pipes conforms to SANS 62 and SANS 719.  All pipes up to 50NB are screwed and anything above 50 NB is flanged.  Dimensional specification – as per required OD size, SDR 13.6, PN 12.5 in accordance with ISO 4427 for piping and ISO S5 for fittings.  Valves conforms to Eskom specification 240-105020315 Standards for Low Pressure Valves. Valve replacement should be confirmed by the Project Manager after inspection/function test.  Check valves are of the full open swing type non return valve.  All piping is supported on support frames.  For steel pipes, the design conforms to BS 3974 Specification for pipe supports, or an equivalent specification approved by Project Manager/.  Supports near flanges do not interfere with the tightening of bolts.  The weight of the pipe and its contents to be accounted for in the design distributed over a broad surface to prevent high concentrated stress.  The chlorine inline mixer is an 80 NB SS316 mixer with flanged connections.  All pipe flanges conforms to SANS 1123 Pipe Flanges.  All pipe bolts and nuts conform to SANS 1700.  Bolts are grade 8.8 and nuts are grade 8.  The gaskets are ASME B16.21, 3 mm thick flat ring type  No Asbestos gaskets ...
