Connection of Pipes a. General
a1. All pipes shall be carefully cut at a right angle against the axial center of the pipes so as to avoid any deformation of the sections, and the cut end shall be finished smoothly.
a2. All pipes shall be connected after removing any chips, dust and other foreign matter and after confirming that all such foreign matter has been completely removed from inside the pipes.
a3. In case piping work is temporarily suspended, all pipes shall be sufficiently protected to avoid the entry of foreign matter.
b. Water Supply Piping
b1. No water supply piping shall be connected according to an insertion system unless specified otherwise.
b2. Epoxy resin synthetic rubber rust inhibitors shall be-sufficiently coated over the end face of threaded portions and the bottom of threaded portions of joints. All rust inhibitors to be applied to any drinking water piping shall not be hazardous to human health and shall not have any adverse effect on drinking water.
c. Drainage and Air Vent Piping
c1. Prior to connecting the galvanized steel pipes, the pipes shall be correctly threaded so that a slight clearance is provided between the end face of pipes and the recess of joints in order to obtain the tapered threaded pipe portion.
The steel pipes shall be screwed tightly into the joints
c2. All cast iron pipes shall be connected by using rubber rings. In this case, the pipes shall be inserted into the rubber rings until the end of spigot comes into contact with inserted into a position near the end of spigot in advance shall be inserted into the pipes carefully so that no twisting will occur in the opening between the socket and spigot. The, the rubber rings shall be set in close contact with the pipes while uniformly fastening the tap bolts and nuts using a junk ring.
c3. All rigid PVC pipe shall be carefully connected by a cold working method so that no ridges or abrupt diameter changes will occur between the connected pipes. The flow of water in the piping shall be smooth and uninterrupted.

c4. All centrifugal reinforced concrete pipes shall be connected by using collars.
After both ends of the joined pipes have achieved tight contact with each other at the central part of the collar and are carefully set in place to ensure proper alignment in the surrounding opening, stiff -consistency mortar shall be placed into the opening. In this case, all cement and water inside the pipes shall be completely removed. In case one end of a pipe is made into a socket from after connecting a collar to the end with mortar, mortar shall be placed about 10 mm away from the pipe end.
Piping
a. Water Supply Piping a1. General
- Prior to execution of piping work, detailed study shall be made on the relationship between other piping and equipment, and all
positions for pipe laying shall be decided by taking into account the precise slope of the respective piping.
In the case where piping is laid inside a building, setting of the pipe support fittings and embedding of pipe sleeves shall be carried our without any delay and in accordance with progress of the work.
- Flange joints shall be inserted for all main piping at appropriate intervals in order to ensure easy removal of such piping.
- In the case where piping is branched from the main piping,
T-joints shall be used.
- Air release valves shall be provided at the dead air space portion
in piping, and a mud discharge valve shall be provided at the portion where mud is collected. The size of the mud discharge valve shall be the diameter of the related pipe, however, the size of the valve shall be 25 mm minimum.
- In case anti-sweat covering is not provided for piping, pipe washers shall be fixed to all portions of piping that penetrate
through ceilings, floors, walls, etc. and is visible from the outside.
- Any openings between the piping that penetrates through fire service areas, etc., shall be filled with rock-wool heat insulation and other noncombustible approved material to maintenance the fire rating of the wall.

between the sleeve and pipe.
- In the case where any steel pipe and similar materials are laid under the ground, such pipe shall be protected against corrosion
by either a double coating of coal tars or a double winding of corrosion proof vinyl tapes (JIS Z1901 "Protective Polyvinyl
Chloride Tapes").
- Any repair of steel pipe, cast iron pipe and lead pipe caulking shall be prohibited.with
- After completion of pipirrig work, the inside of the piping shall be cleaned by water pressure during of hydrostatic testing of the
piping. In the case of piping for drinking water, the piping shall be sterilized until free residual chlorine of 0.2 ppm or over has been
detected at the end of the piping.
a2. Gradient
In the case of horizontally running pipe, the up feed pipe shall have an upward slope and the down feed pipe shall have a downward slope. In principle, the gradient shall be 1/250.
a3. Support Pitch
- The support pitch of the horizontally running pipes shall, in principle, be in accordance with the values in the following table
and, wherever necessary, all bent sections and branching sections shall be supported. In the case where steel pipes or
similar pipes are supported with hangers, a steady rest shall be provided for each horizontally running pipe in order to avoid
