subject: Pipe Fittings Can We Do [print this page] In the traditional decoration, interior decoration materials used in fire safety products has not been a concern, but this year a major new building of CCTV Yuan Xiaoye fire, the issue will be building materials used in the future become an important key programmer selection basis.
Unfortunately, hookah the fire resistance of the relatively high cost of wooden plates, plus a plate of furniture and to do this marketing is not ideal, the state promulgated the provisions of a rubber stamp.
Plastic composite pipe is the first replacement cast iron pipe water supply pipe, its basic structure should be five, that is, from the inside were plastic, hot melt adhesive, aluminum alloy, hot melt adhesive, plastic.
In short, the problem is extremely heavy fire, stainless steel pipe fittings how fire will reduce the losses to a minimum, material selection is an important point! Here, I appeal to business practitioners and architectural decoration for interior decoration of the ordinary homeowner, do not lose the greater, choose quality materials and excellent decoration!
As the water supply pipe, aluminum plastic composite pipes have adequate De strength, but if too large transverse force, will affect the strength, are better bmw ops for Ming wall pipe construction or buried within, but Buyi buried underground. Aluminum plastic composite pipe is a ring-type connection, so the construction it is necessary to pass a stringent test pressure, test the connection is solid. pipe fittings Second, to prevent frequent vibration, so that card set loose. Third, the length of the installed capacity should remain sufficient to avoid pull off.
Plastic pipe welding using hot-melt, high reliability, as long as the tacho universal construction is correct, the normal pressure test the pipeline by welding, no leakage loss.
According to GB/T18742.2-2002 national standards, according to size of pipe into S5, S4, S3.2, S2.5, S2 five series. S with nominal pressure tube have vas 5054a corresponding relationship between the pipe size pipe series S, the nominal diameter dn * Nominal wall thickness en, said the main test the nominal pipe diameter, the average tube diameter and with the corresponding wall thickness, Socket pipe fittings of nominal size and the corresponding diameter.
