A DEVICE FOR PROVIDING SUPPORT FROM BENEATH THE PIPING, BUT OFFERING NO RESISTANCE OTHER THAN FRICTIONAL TO HORIZONTAL MOTION.
A SUPPORT WHICH INCLUDES ONE OR MORE LARGELY ELASTIC MEMBERS (I.E., A SPRING).
THE USE OF RADIANT ENERGY IN THE FORM OF NEUTRONS, X-RAYS OR GAMMA RAYS FOR THE NONDESTRUCTIVE EXAMINATION OF OPAQUE OBJECTS. IT PRODUCES GRAPHICAL RECORDS ON SENSITIZED FILMS WHICH INDICATE THE COMPARATIVE SOUNDNESS OF THE OBJECT BEING TESTED.
THIS WORD HAS TWO MEANINGS DEPENDING ON THE CONTEXT.
(A) THE INTERFACE BETWEEN TWO COMPONENTS, SUCH AS AT A WELD,FLANGE, OR THREADS.
(B) IN PIPELINE APPLICATIONS, A SINGLE SECTION OF STRAIGHT PIPE BEFORE BEING WELDED INTO A LONGER SECTION.
IS A TUBE WITH A ROUND CROSS SECTION CONFORMING TO THE DIMENSIONAL REQUIREMENTS FOR NOMINAL PIPE SIZE AS TABULATED IN ASME B36.10M, TABLE 1, AND ASME B36.19M, TABLE 1. FOR SPECIAL PIPE HAVING A DIAMETER NOT LISTED IN THESE TABLES, AND ALSO FOR ROUND TUBE, THE NOMINAL DIAMETER CORRESPONDS WITH THE OUTSIDE DIAMETER
A DEVICE WHICH RESTRICTS TRANSLATIONAL MOVEMENT TO A LIMITED AMOUNT IN ONE DIRECTION ALONG ANY SINGLE AXIS. PARALLELING THE VARIOUS STOPS, THERE MAY ALSO BE: DOUBLE-ACTING LIMIT STOPS, TWO-AXIS LIMIT STOPS, ETC.
A SUPPORT BY WHICH PIPING IS SUSPENDED FROM A STRUCTURE OR OTHER FIXED POINT LOCATED ABOVE IT, AND WHICH FUNCTIONS BY CARRYING THE PIPING LOAD IN TENSION.
A DEVICE PREVENTING ROTATION ABOUT ONE OR MORE AXES DUE TO BENDING MOMENT OR TORSION. IN COMMON USAGE, A GUIDE NORMALLY PERMITS TRANSLATION ALONG THE PIPE AXIS BUT PREVENTS TRANSLATION PERPENDICULAR TO THE PIPE AXIS.
A FLEXIBLE PRESSURE-CONTAINING COMPONENT OF A PIPING SYSTEM WHICH IS DESIGNED TO ABSORB THERMAL MOVEMENT.
A DASHPOT OR OTHER FRICTIONAL DEVICE WHICH INCREASES THE RESISTANCE OF A SYSTEM TO VIBRATION. IT OFFERS HIGH RESISTANCE AGAINST RAPID DISPLACEMENTS CAUSED BY DYNAMIC LOADS, WHILE PERMITTING ESSENTIALLY FREE MOVEMENT UNDER GRADUALLY APPLIED DISPLACEMENT SUCH AS FROM THERMAL EXPANSION.
A SUPPORT WHICH IS CAPABLE OF APPLYING A RELATIVELY CONSTANT FORCE AT ANY DISPLACEMENT WITHIN ITS USEFUL OPERATING RANGE (I.E., A COUNTERWEIGHT OR COMPENSATING SPRING DEVICE
THE INTENTIONAL STRESSING AND ELASTIC DEFORMATION OF THE PIPING SYSTEM DURING THE ERECTION CYCLE TO PERMIT THE SYSTEM TO ATTAIN MORE FAVORABLE REACTIONS AND STRESSES IN THE OPERATING CONDITION.
A DEVICE PRIMARILY INTENDED TO RESIST PIPING DISPLACEMENT DUE TO THE ACTION OF ANY FORCES OTHER THAN THOSE DUE TO THERMAL EXPANSION OR GRAVITY.
A MECHANICAL DEVICE USED TO TIGHTEN BOLTS BY APPLYING A UNIFORM, CALIBRATED LOAD. IT ATTACHES TO THE END OF THE BOLT, STRETCHES IT BY APPLYING A LOAD, AND THEN PERMITS EASY TURNING DOWN OF THE NUT TO HOLD THE LOAD IN THE BOLT.
A RELATIVELY NARROW, CIRCULAR SECTION PLACED IN BACK OF A BUTTWELDED JOINT PRIOR TO MAKING THE ROOT PASS OF THE WELD. THIS IS DONE TO ACHIEVE A FULL-PENETRATION WELD WHEN THE BACK SIDE OF THE WELD JOINT CANNOT BE ACCESSED.
USE OF AN ELECTRIC ARC GENERATED AT THE TIP OF A WELDING ELECTRODE TO CUT METAL.
USED TO MAKE STEEL SOFT & DUCTILE BY HEATING A METAL TO TEMPERATURE ABOVE CRITICAL TEMPERATURE FOR A PERIOD FOLLOWED BY COOLING @ SUITABLE RATE ACCORDING TO THE PURPOSE
