SEAMLESS PIPE WORK MADE OF COLD ROLLED CARBON STEEL. CONNECTED TO OTHER PIPEWORK BY BUTT WELDING. THE PIPE WORK IS USED FOR CONNECTING THE VARIOUS PIECES OF WELL TEST EQUIPMENT TOGETHER ON THE RIG. THE PIPE WORK FOR VARIOUS TYPES OF END CONNECTIONS IS AVAILABLE. HAMMER UNION CONNECTED PIPE WORK IS MOST COMMONLY USED DUE TO THE EFFICIENT 'RIG-UP AND RIG-DOWN' TIME. ALL PIPE WORK IS PRESSURE AND TEMPERATURE RATED TO MEET HOSTILE ENVIRONMENTS. PRESSURE RATINGS FOR PIPE WORK ARE 10,000PSI OR 15,000PSI. THE EXTERNAL DIAMETERS 75mm; 100mm; 150mm (3 INCHES; 4 INCHES; 6 INCHES). CARBON EQUIVALENT VALUE (CEV) 0.36-0.40.
