Pressure gauges shall be provided on the discharge side of all pumps, and pressure/vacuum gauges shall be provided on the suction of all positive displacement pumps.

Temperature gauges shall be provided on all piping which transfers a medium in excess of ambient temperature.

C. PIPING – GENERAL REQUIREMENTS

The use of the designation “line” in this specification is defined as all pipe, fittings, and valves in a piping run between the points indicated.

Piping shall be sized and arranged to obtain optimum operating conditions for the equipment and intended service. Items of piping not covered in these specifications, but required for proper installation and operation shall be furnished and installed the same as if specified.

System design shall route all piping as directly as practicable; shall not interfere with machinery access or handling gear; and shall be sufficiently flexible and supported to account for thermal expansion, shock, vibration and the working of the vessel. Where pipes penetrate structure, reinforcement of the opening may be required. Wherever practicable, piping shall be run below the grating or sole level. No piping runs shall be made through access openings.

A sufficient number of unions and/or flanges shall be installed in all pipe lines to permit dismantling of the lines and equipment, and rigging that equipment out of the space for repair or replacement. Valves shall be installed in sufficient quantity to isolate any piece of equipment in the systems.

Pipes passing through decks, watertight or oil tight bulkheads shall be made of Sch 80 pipe in that section, in way of the penetration and the bulkhead or deck shall maintain its integrity. Where pipes pass through watertight bulkheads or decks, the penetrations shall be watertight.

Heat sensitive materials shall not be used in piping systems that penetrate watertight subdivisions where deterioration of such systems would, in the event of a fire, impair the watertight integrity of such bulkheads. Copper tubing that penetrates watertight bulkheads and decks shall use a suitable stuffing tube. Spool pieces with flanges shall be provided for all galvanized pipe penetrations to prevent the destruction of galvanizing due to welding.

All piping exposed in unheated spaces or to the weather and carrying fluids that can freeze shall be electrically heat traced, except that the fire main piping may be designed such as to be a dry system when not pressurized. Freeze protection shall be provided by installing drain plugs at all low points in all piping systems carrying fluids that can freeze.

All piping shall be Sch 40, ASTM A-53, Type S or E except where otherwise indicated.

All piping between the side shell and the first inboard valve shall be a minimum of Sch 80 (see Clause C301.G. for further details). Fasteners for valves at the hull connections shall be stainless steel. All tank penetrations shall be through Sch 80 welded couplings unless specified elsewhere.

No cast iron valves or wafer valves shall be used at shell connections.

All steering system hydraulic line and fuel oil lines shall be welded connections.

Threaded connections on these systems are prohibited with the exception of use with flexible hose connections where required (ex. engine connections).

Manually operated valves shall be readily operable by one person, directly or through mechanical advantage type operators.

Check valves shall be of a type best suited for the service condition, especially the flow velocity to ensure that the valve will fully open. A check valve shall be installed where a reversal of flow is possible and would be detrimental to the proper functioning of the system, or might be injurious to equipment.

Gate valves are intended to be fully open or fully closed and shall not be used for throttling the flow.

All lines leading to the overboard discharges shall be angled downward sloping 45-degrees or better toward the water line.
