PART 3 EXECUTION

3.1 GENERAL

A. Piping fabrication and installation shall conform to the requirements of Chapter V of ANSI B31.3.  Pipe, trays, and tubing shall be installed parallel with, or at right angles to, the structural members of buildings; vertical runs shall be straight and plumb. Tubing bends shall be tool-formed without flattening, and shall be all of the same radius to ensure good appearance. Care shall be taken to keep tubing runs away from hot pipes, and under no circumstances shall they be less than 12 inches from any such pipe. Individual pipe, tubing runs, and instrument capillary tubing shall be continuously

supported in channels, trays, or from structures so that mechanical damage will not occur, and shall be clipped in place. Tubing trays and channels shall be located in such a manner that they will not catch spillage, overflow, or dirt from above.

B. Cut tubing square and remove burrs.  Clean both inside of fittings and outside of tubing with steel wool and muriatic acid before sweating. Take care to prevent annealing of fittings and hard-drawn tubing when making connections.

C. Bends in soft temper tubing shall be long sweep, wherever possible.  Bends shall be shaped with bending tools and shall be made without appreciable flattening, buckling, or thinning of the tube wall at any point.
