Pipe configuration needs to be cost conscious the design can be under 10% of excess pipe to get from point to point straight line distance, which is excellent from a piping material and pressure loss point of view.
The total cost of pipe installation can be US$ 600-1,200 per meter of pipe. The two-phase line can be in the range 50 to 150 m, the steam lines from 2000 to 3000 m and for the brine up to 6000 m long. Pipe diameters are generally 250 to 1219 mm nominal pipe size. Pipe pressure design for the separation station and steam lines is 1.5 MPa, and for brine line ranges from 1.5 to 4 MPa. The allowable stress is S E =88 MPa for ERW pipe and S E =103 MPa for seamless pipe, S A =155 MPa for operation load, kS h =124 MPa for earthquake load and 258 MPa for combined sustained loads and stress range. The principal design codes used for piping design are the ANSI/ASME B31.1 (Code for Power Piping) and ANSI/ASME B31.3 (code for process piping), ASTM A53 B, ASTM A106 B and API 5L carbon steel pipes are the ones used for geothermal fields. The expansion loops most commonly used in crosscountry pipelines are L bends, Z bends, conventional 90° elbow and V bends. This requires the consideration of installation cost, pressure loss effect on production, stress level concern, fatigue failure, support and anchor effects, stability, easy maintenance, parallel expansion capacity and others.
The Isometric is commonly referred to as oriented towards the North direction marked with an arrow in the top right corner. That’s why calculating various data from an Isometric coordinate system is required. The best piping configuration is the least expensive over a long term basis. As we already know, Piping isometric drawing is drawn to scale.
