Abstract
The utility model discloses a special material welding connector which is suitable for welding connection of aluminum alloy and stainless steel of a liquid natural gas (LNG) inlet. The special material welding connector comprises an aluminum alloy pipe section and a stainless steel pipe section. The aluminum alloy pipe section and the stainless steel pipe section are fixedly connected through an aluminum transition layer. The special material welding connector is suitable for a LNG inlet end of an open rack vaporizer, can effectively avoid the phenomena of leakage, deformation, and the like which may occur in flanged connection, and simultaneously has the advantages of being simple in structure, reliable in performance, safe in connection, and capable of reducing vibration influence at gasifying time.
Description
Technical field
The utility model relates to a kind of foreign material and is welded to connect joint, specifically refers to a kind of aluminium alloy and stainless steel welded joint for the connection of LNG open-frame type gasifier entrance.
Background technology
At the LNG(liquefied natural gas) in the receiving station, LNG defeated use outward at first will be through gasification.Use at present most often open-frame type gasifier.Because the gasification of LNG is to normal temperature from-162 ℃ low temperature direct gasification, therefore the heat-transfer pipe of gasifier is selected is low temperature resistant corrosion-resistant and aluminum alloy materials that heat transfer coefficient is very high, is the austenitic stainless steel material with good low temperature performance entirely and external pipeline adopts.Adopt flange to connect between the two, because material is different, difference variation is very large, often causes the junction to deform, leak, and has potential safety hazard.
The utility model content
The utility model provides a kind of foreign material to be welded to connect joint, solves in the above-mentioned flange connection because of the issuable security hidden trouble of temperature difference strain.
For this reason, the technical scheme that adopts is: a kind of foreign material is welded to connect joint, and described foreign material welding point comprises aluminium alloy pipeline section and stainless steel pipeline section, and both are affixed by the aluminium transition zone.
Described affixed employing argon arc welding welding.
The utility model is applicable to the LNG arrival end of open-frame type gasifier, can effectively avoid the problems such as leakage that flange may occur in connecting, distortion.Have simultaneously simple in structure, dependable performance, connect the advantage of safety, the vibration effect in the time of also reducing gasification.
Description of drawings
Fig. 1 is the connection diagram of the utility model and LNG arrival end;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 2, a kind of foreign material is welded to connect joint, and described foreign material welding point comprises aluminium alloy pipeline section 2-1 and stainless steel pipeline section 2-3, and both adopt the welding method of argon arc welding to connect by aluminium transition zone 2-2.
Processing method of the present utility model is: plate transition zone 2-2 aluminium powder at stainless steel pipeline section 2-3 end face first, behind the coating stabilized metal, adopt argon arc welding with aluminium alloy pipeline section 2-1 and the stainless steel pipeline section assembly welding that has plated aluminium powder, thereby form aluminium alloy and stainless steel dissimilar material welding point.
With reference to Fig. 1, among the figure: 1-LNG inlet connection, 2-the utility model 3-external stainless steel pipeline
Using method of the present utility model is: aluminium alloy inlet connection 1 welding of aluminium alloy pipeline section 2-1 of the present utility model and gasifier, link to each other with the arrival manifold of open-frame type gasifier, and external pipeline 3 welding of stainless steel pipeline section 2-3 of the present utility model and stainless steel.
Claims (2)
1. a foreign material is welded to connect joint, it is characterized in that: described foreign material welding point comprises aluminium alloy pipeline section (2-1) and stainless steel pipeline section (2-3), and both are affixed by aluminium transition zone (2-2).
2. a kind of foreign material according to claim 1 is welded to connect joint, it is characterized in that: described affixed employing argon arc welding welding.
