Advantages of using our ISO Piping Program
Our mission in the oil, gas, petrochemical, pulp and paper industries is to produce a high quality as built ISO drawings saving you time and money.
We utilize existing standards to update or create field as built CADD ISO sketches to meet your needs. Emphasis on key points such as: flow direction, existing TML, RT, and Injection points, line numbers, specification breaks, drawing & circuit orientation, drawing numbers, and reference points are stressed on each as built drawing.
We facilitate NDE personal by providing up to date ISO drawings, and pre-marking piping systems, expedite removal of insulation saves you: money by reducing re-shots, time locating UT or RT point's which are not marked, time to come back to take readings because insulation was not removed, and finding future corrosion or erosion points.
Our drawings can be used to aid in emergency shut down procedures, preventive maintenance programs or API inspections.
Flagging and/or marking of the piping systems during the as built ISO drawing or verification stages ensures that the TML's on the piping systems are easily found and the shot orientation required can be made.
Our flagging program reduces time in finding TML locations, expedites the removal of insulation, and describes the level at which the TML are taken from (JLG, ladder, scaffold, ground) prior to NDE technician’s arrival.
We have developed a clock position technique for locating exact positions on piping systems. Using our clock positioning technique procedure increases shot accuracy and repeatability, and most important reduces wasted time.
Piping Clock Positioning Technique
The example below is a simple section of how the vertical component can be determined by a horizontal pipe orientation. Right hand rule is a technique, which can be used for determining the clock position on piping for taking RT reading.
Twelve, and six o’clock positions are always located on the top and bottom of piping respectively. Girth welds are key transition points, which determine the ownership of fittings.
Three and nine clock positions are always located on either side of the piping, and their orientation can be determined by pipe flow direction with the right hand rule in mind.
Right Hand Rule:
Point your thumb in the direction of fluid flow, with your fingers in the vertical position (fingers point to the sky). Your fingers now point to twelve o’clock. As you curl your fingers (or make a fist) from twelve o’clock position you now approach one o’clock and increase back to twelve o’clock. With confidence three and nine o’clock positions are known. In this converging flow case the TEE has the same clock position as the vertical section. The vertical section clock position is determined by the upper horizontal piping.
Creating as built part drawings for oil field equipment is also an integral part of our business.
Updating part drawings, 3d drawings and P&ID's in your existing files.
