Description
Technical field
The utility model relates to a kind of pipe fitting, particularly one is used for fire fighting supply, combustion gas, heats, drinks the metallic conduit clasp type linkage structures such as hot and cold water, draining, air conditioner water, pressurized air and penetration pipe, and this clasp type linkage structure can reduce installation cost and improve installation efficiency and the safety and reliability can strengthening pipeline connection.
Background technique
Along with the accelerated development of science and technology and the mutual reference in domestic and international constructed field, stainless steel nearly ten years, copper, carbon steel tubing clamp-press type pipe all adopts thin walled tube to design at the running water pipe of house or building or other fluid conveying metallic conduits, owing to have employed thin wall-type, tubing own wt is light, substantial saving in material, be specially adapted to the pipe arrangement of skyscraper, and construction is simple, operating time is short, joint is without being threaded, without complicated mantle fiber operation, without high temperature naked light, pre-process and post-process during welding, oil pollution when cutting without construction or be connected or welding slag pollute, crimp with special tool, pipe fitting connection completes instantaneously.
But in the fire-fighting spraying pipeline system of building, corrosion resistance is strong, the high-end tubing such as the clamp-press type copper pipe of long service life and jam-on stainless steel pipe cannot enter fire-fighting spraying pipeline system because price is high, so that Fire Protection Card pressure type connecting tube now, still the zinc-plated thin walled tube of carbon steel material has been continued to use, Placement still adopts clamp-press type, and cartridge connection uses the cost performance having embodied height on Stainless Steel Tube and copper pipe! Because stainless steel and copper pipe inherently have very strong corrosion resistance and pipeline long service life, connect the features such as safe and reliable, but the zinc-plated carbon steel tube of fire-fighting adopts cartridge connection to be used in spraying system of fire fighting and to there is very large defect and hidden danger.
In cartridge connection, crimping tool crimps for socket section and seal groove two place simultaneously, seal groove position is compressed, the O RunddichtringO in groove is forced to be close to steel pipe, play the effect of hermetic seal, socket section is subject to hexagonal card pressure, Steel pipe and fitting extrusion-deformation, utilize the rigidity of metallic material itself, play anti-pulling effect, card pressure technology very ripe in the connection of stainless steel and copper tube praise highly by the whole world, be used in hospital in large quantities, the potable water engineering of star hotel and high-end residential, but on the zinc-plated carbon steel tube of fire-fighting spraying, utilize card pressure technology will there is very large defect and hidden danger! because clamp-press type pipe socket section is subject to hexagonal card pressure, Steel pipe and fitting friction and Extrusion is out of shape, the zinc coat of Coating Steel Pipe outer wall and pipe fitting inner wall is caused to be destroyed, and the current in pipeline are by flowing in intubate gap, through hexagonal extrusion-deformation position, now the zinc coat of Steel pipe and fitting inwall is destroyed, and carbon steel tube and pipe fitting are etched oxidation under the effect of current, and the working life of fire protection pipeline will have a greatly reduced quality! too impatient to wait, need to improve.
