Description
Technical field
The invention belongs to pressurized-water reactor nuclear power plant main equipment manufacturing technology fields, and in particular to a kind of nuclear power main equipment safety
End and its manufacturing process.
Background technique
Pressurized-water reactor nuclear power plant primary device connection tube mouth is low-alloy steel material, and main pipeline is stainless steel material, due to scene
Installation does not have hidden lino removal implementation condition, and low-alloy steel pressure inlet is first welded one section of Ovshinsky in manufactory at present
Body stainless steel takes over as safe end, and when in-site installation welds safe end and pipeline, since safe end and pipeline are Ovshinsky
Body stainless steel does not need preheating and hidden lino removal, therefore site welding difficulty substantially reduces, and welding quality obtains effectively
Guarantee.
Existing safe end is austenitic stainless steel adapter tube, and pressure inlet and safe end are xenogenesis weld, dissimilar metal
Because of the difference of chemical component, physical property etc., welding difficulty is big, and in the device fabrication stage, the xenogenesis weld is easy to appear and asks
Topic, usually spends a large amount of manufacturing time, seriously affects the manufacturing cycle of equipment.
Summary of the invention
The technical problem to be solved in the invention are as follows: existing safe end is austenitic stainless steel adapter tube, pressure inlet and peace
Quan Duanwei xenogenesis weld, welding difficulty is big, often generates welding defect, needs to take a significant amount of time weld and reprocess,
Production efficiency is low.
It is described that technical scheme is as follows:
A kind of nuclear power main equipment safe end, including the side to be connect with low-alloy steel material pressure inlet and and Ovshinsky
Body stainless steel material main pipeline side to be connected: the side of nuclear power main equipment safe end is low-alloy steel material, the other side
For austenite stainless steel material.
As a preferred solution: the side of nuclear power main equipment safe end is 18MND5 or 16MND5 or 20MND5 or SA 508
508 Gr3Cl1 low-alloy steel of Gr3Cl2 or SA, the other side are that Z2CND18-12 controls nitrogen or 316LN austenitic stainless steel.
A kind of nuclear power main equipment safe end manufacturing process, including following process: processing and fabricating low-alloy steel blank respectively
With austenite stainless steel blank；Connect low-alloy steel blank and austenite stainless steel blank；To the low-alloy steel being connected as one
Blank and austenite stainless steel blank successively carry out forging upset operation, processing inner hole, circumferential forging reaming.
As a preferred solution: connecting low-alloy steel blank and austenite stainless steel blank using friction welding technological.
As a preferred solution: when processing inner hole, in the low-alloy steel blank and austenite stainless steel blank being connected as one
Middle part process through-hole.
The invention has the benefit that
Nuclear power main equipment safe end of the invention, side are low-alloy steel, and side is austenitic stainless steel: guaranteeing equipment
When workshop manufactures, low-alloy steel material pressure inlet and the welding of safe end low-alloy steel side belong to low-alloy steel material of the same race for manufactory
Material welding, the probability that the difficulty and defect for greatly reducing welding generate, shortens manufacturing time；Austenite stainless steel at the scene
When matter main pipeline and safe end austenitic stainless steel side are welded, belongs to the welding of stainless steel same material, do not need preheating and postwelding
Hidden lino removal.
Nuclear power main equipment safe end of the invention, can effectively avoid the xenogenesis weld in equipment Manufacture Process from asking
Topic, is greatly shortened welding interval, the welding quality significantly improved, can be applied to pressurized-water reactor nuclear power plant main equipment safety
End, thoroughly solves the problems, such as the xenogenesis weld in equipment Manufacture Process, has filled up the blank both at home and abroad in this field, had
Vast market prospect.
