Abstract
The utility model relates to a forge the pipe flange in stainless steel build -up welding or the stainless steel composite sheet equipment, especially little internal diameter flange specifically is a pipe flange is forged to little internal diameter. The problem of current pipe flange is forged to little internal diameter is for realizing anticorrosive existence is solved. This pipe flange is forged to little internal diameter by the carbon steel forge tub, weld in the carbon steel forge tub one end the carbon steel flange, overlap the nonrust steel pipe of inside lining in pipe and carbon steel flange are forged to the carbon steel and regard as the stainless steel overlay of the sealed face of carbon steel flange to constitute nonrust steel pipe of inside lining and the carbon steel flange joint. The utility model discloses simple structure, the easy realization, not only realized anticorrosively, practiced thrift valuable material moreover, reduced equipment cost, avoided the welding of xenogenesis steel, can not crack, caused the incident, overcome the not enough of prior art.
Description
Technical field
The utility model relates to the forging pipe flange in stainless steel built-up welding or stainless steel clad plate equipment, particularly little internal diameter flange, is specially a kind of little internal diameter forging pipe flange.
Background technique
In order to save precious materials, stainless steel built-up welding or stainless steel clad plate equipment are used widely in chemical industry, but little internal diameter is forged, and pipe flange is anticorrosion to be had the following disadvantages: 1, little internal diameter forging pipe flange adopts built-up welding stainless steel material anticorrosion, because internal diameter is too little, by the restriction of equipment and technology condition, cannot realize.2, little internal diameter forging pipe flange adopts all steel material antiseptic, causes precious materials waste, increases device fabrication cost, and be different steel weld during case weld, easily crack, initiation security incident.
Summary of the invention
The utility model solves existing little internal diameter forging pipe flange for realizing anticorrosion Problems existing, provides a kind of corrosion-resistant little internal diameter forging pipe flange.
The utility model adopts following technological scheme to realize: little internal diameter forging pipe flange, forge pipe by carbon steel, be welded in carbon steel forge pipe one end simple steel flange, be placed on carbon steel and forge pipe and the inner liner stainless steel pipe in simple steel flange and the stainless steel weld overlays of the sealing surface as simple steel flange that is connected with simple steel flange by inner liner stainless steel pipe is formed.
The utility model structure is simple, easily realizes; Not only achieve anticorrosion, and saved precious materials, reduce equipment cost, avoid different steel weld, can not crack, cause security incident, overcome the deficiencies in the prior art.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-carbon steel forging pipe, 2-inner liner stainless steel pipe, 3-simple steel flange, 4-stainless steel weld overlays, 5-housing basic unit (carbon steel), 6-housing cladding (stainless steel).
Embodiment
Little internal diameter forging pipe flange, forge pipe 1 by carbon steel, be welded in carbon steel forge pipe one end simple steel flange 3, be placed on carbon steel and forge pipe and the inner liner stainless steel pipe 2 in simple steel flange and the stainless steel weld overlays 4 of the sealing surface as simple steel flange that is connected with simple steel flange by inner liner stainless steel pipe is formed.During use, the other end (non-flange end) of this little internal diameter forging pipe flange, carbon steel forging pipe 1 welds with the housing basic unit (carbon steel) 5 of equipment, inner liner stainless steel pipe 2 welds with the housing cladding (stainless steel) 6 of equipment, like this, not only achieve anticorrosion, and avoid different steel weld, can not crack.During concrete enforcement, simple steel flange 3 is band neck welding neckflange, to make more reasonable structure.
Claims (2)
1. a little internal diameter forging pipe flange, it is characterized in that forging pipe (1) by carbon steel, be welded in carbon steel forge pipe one end simple steel flange (3), be placed on carbon steel and forge pipe and the inner liner stainless steel pipe (2) in simple steel flange and the stainless steel weld overlays (4) of the sealing surface as simple steel flange that is connected with simple steel flange by inner liner stainless steel pipe is formed.
2. little internal diameter forging pipe flange according to claim 1, is characterized in that simple steel flange (3) is for band neck welding neckflange.
