Piping Clause Samples
The Piping clause defines the requirements and standards for the installation, materials, and workmanship related to piping systems within a project. It typically outlines specifications for the types of pipes to be used, installation methods, testing procedures, and compliance with relevant codes or regulations. For example, it may require the use of specific materials for water supply lines or mandate pressure testing before commissioning. The core function of this clause is to ensure that all piping work meets safety, quality, and regulatory standards, thereby reducing the risk of system failures and ensuring reliable operation.

Piping. A. Provide and erect in a workmanlike manner according to the best practices of the trade, all piping shown on the plans or required to complete the installation intended by these specifications.
B. This contractor shall inform himself from the Engineer's specifications and detailed drawings of the exact dimensions of finished work in all rooms where equipment or pipes are to be placed, and arrange his work accordingly, assuming all responsibility for conformity with the surrounding work.
C. In the erection of mains, special care must be used in their support and proper allowance shall be made for expansion.
D. All steel piping larger than 2" shall have welded joints made by experienced pipe welders. The joints shall all be well filled with metal without interior projections. After welds are made, this contractor shall thoroughly clean inside and leave a smooth bore. Where connections are made on runs, weld-o-lets or thread-o-lets are to be used.
E. All other connections are to be made with screwed fittings.
F. In making welds, this contractor is to have the end of the pipe properly beveled and perfectly lined up.
G. Keep plugged or capped all openings in pipes or fittings.
H. Connections to mains are to be provided with swing arms to provide for expansion.
I. Make such offsets as are shown or required to place pipes on risers in proper position or to avoid other work. Make such offsets neatly and properly locate them to the satisfaction of the Engineer.
J. All pipe lines are to be provided with sufficient number of flange fittings or unions to make possible the taking down of the pipes without breakage of fittings. Lines 2" in diameter and less may be connected by R & L couplings, unless otherwise required by the Engineer. All of the piping shall be erected so as to provide for the easy flow of water and noiseless circulation. Whenever pipes are cut, three-wheel cutters are to be used and the pipes are to be carefully reamed out.
K. Due to the extreme limited headroom, all water mains shall be installed perfectly level or with minimum pitch. Install air vents on all high points and drawoff valves on all low points throughout the entire system.
L. The entire piping system shall be provided with shutoff valves and drawoff valves so that sections of the system may be drained without interrupting the entire system.
M. Extreme care shall be exercised in the location of all piping.
N. No crosses or bull head tees shall be used in any part of the work.
O. Piping...
Piping. TS-945 Each part of the piping systems shall be complete in all details and provided with all control valves and accessories necessary for satisfactory operation. TS-946 The drawings indicate generally the sizes of all main piping, and while the sizes are not to be decreased the Managing Official reserves the right to change the runs and sizing of piping to accommodate conditions arising during construction. TS-947 All pipe work, valves, fittings etc. are to be as detailed for various services in the Schedules. TS-948 All piping shall be grouped wherever practical and shall be erected to present a neat appearance. Pipes shall be parallel to each other and parallel or at right angles to structural members of the building and shall give maximum possible headroom . TS-949 All pipe drops shall be truly vertical, drain piping shall pitch down in direction of flow, and all pipework shall be installed with a continuous gradient to allow natural circulation, air venting and drainage. Levels are to be approved by the Managing Official. TS-950 Run outs shall be graded in such a manner as to prevent air traps being formed within them when the mains expand or contract.
Piping. Water supply and drain piping shall be type “L” copper and insulated with “Arma-Flex” ¾” nominal wall thickness closed cell foam insulation. Supply piping to
