水工施工工艺(国外英文资料) Hydraulic construction process (home furnishings) A, slot 1, the groove width is 10 to 20mm per side The depth of the cold water is 10 mm from the wall, the hot water pipe is 15 mm from the wall The parallel vertical spacing is greater than 200 mm when the hot water pipe is slotted Pipe laying 1, if there is hot and cold water, vertical, left hot right cold, parallel time, upper heat is cold and the distance between the two tubes is greater than 200 mm Pipe outlet position A, wash bath should be in 1200 millimeter, if have pelvic bath should be 630 millimeter B, the wash basin, the bottom water is 450 mm, the top is 1000 mm C, toilet seat, water next 250 mm (commonly used), up to 580 mm (not used) D, the mop should be in 800 mm, the washing machine USES 1200 mm 3, when the ground laid, fixed time interval should be in 1 m to 1.2 m, by 1:2 cement mortar protection, the condole with fixed tube and roof span should be 10 mm or more, hot water is 600-800 mm, 800-1000 mm cold water, vertical fixed, 500-600 mm hot water, cold water 600-800 mm, but at the outlet of 150-200 mm must be fixed. Pipe connection 1, the aluminum composite works special pipe, but no joint at the installation 2, PPR pipe connection, must use the same parts manufacturer, and according to the manufacturer to provide, hot melt tool and the heating temperature of 260 degrees - 270 degrees c + / - 5 degrees Celsius, the heating time for 10 seconds or so commonly, cooling time is 3 to 4 minutes, pay attention to in 4 seconds after heating tubes inserted into the pipe is not allowed to turn the pipe fittings and pipe 3, PPR tube welding procedure A, note that the length of the piping heating is equal to the depth of the joint The schedule is as follows: Pipe diameter The depth of the weld Solution time (second) Insertion time (second) Cooling time (minutes) 20 14 5 4 2-3 25 15 7 4 2-3 Note: when the temperature change is less than 5 degrees Celsius, the heating time is increased by 50% 4,
