SEAMLESS PIPES MADE OF COLD ROLLED CARBON STEEL. CONNECTED TO OTHER PIPEWORK BY BUTT WELDING. THEY ARE USED AS ARE PART OF A WELL TEST PRODUCT LINE THEY ARE ATTACHED TO A PORT AND ARE DESIGNED TO ACCURATELY MEASURE AND RECORD THE PRESSURE AND TEMPERATURE OF FLUIDS PRODUCED BEFORE THE PASS THROUGH THE CHOKE MANIFOLD BY BOTH MANUAL & ELECTRONIC MEANS. DATA HEADERS HAVE 3 OR 4 PORTS WHERE DATA IS COLLATED. THE HEADERS ARE LINED PIPE WORK THAT IS FITTED WITH ½" NPT HALF COUPLINGS WITH A ¾" NPT HALF COUPLING USED TO TIE IN A TEMPERATURE PROBE. THE TEMPERATURE PROBE IS NOT PART OF THIS BTI, ONLY THE DATA HEADER DUE TO IT BEING MODIFIED PIPE WORK. THE EXTERNAL DIAMETERS 75mm; 100mm; 150mm (3 INCHES; 4 INCHES; 6 INCHES). CARBON EQUIVALENT VALUE (CEV) 0.36-0.40. THERE ARE NOT TESTING OR ELECTRICAL APPARATUS INCLUDED.

CLASSIFICATION IS DETERMINED IN ACCORDANCE TO THE FOLLOWING: GENERAL INTERPRETATIVE RULES (GIR)S GIR 1 HAS BEEN USED TO CLASSIFY THIS PRODUCT BY THE TERMS OF HEADING 7304 - TUBES, PIPES AND HOLLOW PROFILES, SEAMLESS, OF IRON (OTHER THAN CAST IRON) OR STEEL. GIR 6 HAS BEEN USED TO CLASSIFY THE GOODS TO SUBHEADING LEVEL 730431 - OTHER, OF CIRCULAR CROSS-SECTION, OF IRON OR NON-ALLOY STEEL. CN CODE 73043180 - COLD-DRAWN OR COLD-ROLLED (COLD-REDUCED), OTHR THEN PRECISION TUBES. TARIC CODE 7304318030 - WITH A CARBON EQUIVALENT VALUE (CEV) NOT EXCEEDING 0.86 ACCORDING TO THE INTERNATIONAL INSTITUTE OF WELDING (IIW) FORMULA AND CHEMICAL ANALYSIS ALSO CLASSIFIED IN ACCORDANCE WITH: HSEN GENERAL NOTE (1) TO CHAPTER 73.
