Description
Technical field
The utility model belongs to field of ship engineering, relates to a kind of high petential metal seawaterline pipe penetration piece with seal ring.
Background technique
Pipe penetration piece is the ship piping system important component part, is to run through watertight compartment, deck, cabin cabinet etc. and can keep each self-packing pipe fitting.Pipe penetration piece generally is comprised of inner tube, junction surface etc., inner tube links to each other with the pipeline junction surface by junction surface on the one hand, directly or indirectly link to each other with Ship Structures such as bulkheads on the other hand, junction surface can adopt the forms such as flange, screw thread, and inner tube, junction surface will guarantee that system media can not leak.Pipe penetration piece commonly used has band copper bush pipe penetration piece (CB 539-67), steel pipe penetration piece (CB/T 3480-92) etc., and the former adopts copper inner tube, and the latter adopts the steel inner tube.
When high conductivity MEDIA FLOW such as seawater during through contacted dissimilar metal, can consist of the macroetching battery, cause low potential metal corrosion aggravation, this corrosion is referred to as electrochemical corrosion.Because its corrosion rate is far longer than this corrosion rate in seawater of metal, must strictly take precautions against.Take steel copper as example, the plain carbon steel electrode potential is-0.6 ~-0.72V, the silicon brass electrode potential is-0.3 ~-0.4V, seawater in a single day flow through contacted steel, copper material, steel will corrode rapidly.
In order to improve piping working life, the high petential metal tubes such as copper tube, brass tube, White Copper Tubes in the pipings such as boats and ships sea water service system, hydraulic system, have been used in a large number.If select CB/T 3480-92 etc. to have the pipe penetration piece of steel inner tube when these pipelines pass hull structure, seawater certainly will contact steel and high petential metal simultaneously, through the loop that flange bolt etc. is located to form, can form the macroetching battery in addition, cause the corrosion of pipe penetration piece steel inner tube.If the pipe penetration piece of selecting CB 539-67 etc. to have copper inner tube, because steel contacts with high petential metal itself, flange seal place seawater contacts steel and high petential metal simultaneously in addition, can form the macroetching battery, causes pipe penetration piece steel partial corrosion.
For this reason, need a kind of like this pipe penetration piece: allow the high petential metal tubes run through steel hull structure and can keep each selfsealing, can not cause again pipe penetration piece itself to corrode.
