Definitions

  • the invention relates to a method for establishing a connection between austenitic steam generator heating surfaces and a container used as a collector or as a distributor, wherein pipe nipple between leading to the steam generator heating surface connecting lines and a collector or container wall of a body of the container installed and each forming an axial gap between the container wall and the pipe nipple are welded at one end directly to the container wall and at the other end to the connecting line.
  • the invention also relates to a container which forms a collector or distributor, with pipe nipples inserted into a container wall of a container base body forming an axial gap between the container wall and the respective pipe nipple, which at one end welds directly to the container wall to form a weld and at the other End are each welded to a leading to a steam generator heating surface austenitic connection line.
  • the austenitic materials have a higher expansion coefficient than martensitic or ferritic materials. This leads to high stresses at the weld joints between materials made of austenitic materials (so-called “white materials”) and those made of ferritic or martensitic materials (so-called “black materials”). So far, so-called black and white connectors are used, which in the example FIG. 3 are formed as connecting pieces 14 of two axially welded pipe pieces of correspondingly different materials and in the unheated area in the connecting lines 15 (see. Figures 1 and 2 ) are welded from the heating surface to the collector 17 or directly in front of the collector 17 between the connecting lines 15 and the collecting nipple 16. It is also known to provide such weld connectors on the boiler side between Walker vomausgang and connecting lines to the collector.
  • black and white connectors can only be manufactured and tested in a complicated manner due to the increased quality requirements that are imposed on them.
  • several welds in the connecting lines to the collector needed, which in turn the assembly and testing costs is further increased.
  • a pipe nipple which is welded into a hole having a wall of a collector, is still in the US-A-4 526 137 disclosed.
  • an inner shell is additionally provided, which should make the inside of the pipe nipple heat resistant.
  • the inner shell is mechanically, ie without welding, connected to the pipe nipple.
  • the inner shell may consist of a different material than the pipe nipple, in particular made of corrosion-resistant material.
  • a generic method and a generic container are from the NL 84 739 C known.
  • a method for establishing a connection between (austenitic) steam generator heating surfaces and a container used as a collector or as a distributor wherein pipe nipple between leading to the steam generator heating surface connecting lines and a container wall of a body of the container installed and in each case to form an axial gap between the container wall and the pipe nipple are welded at one end directly to the container wall and at the other end to the connecting line.
  • the pipe nipple is inserted into a container wall of a collector, which does not yet have a connection bore, before a bore leading into the interior of the collector is then subsequently made while boring the pipe nipple.
  • this document is not a reference to the materials used in each case and cooperating in the context of welds of collectors or containers, Remove pipe nipples and connecting pipes to the steam generator heating surfaces.
  • the invention has for its object to provide a connection between steam generator heating surfaces and a container used as a collector or as a distributor, with which reduces the assembly and testing costs of the compound, the inherent and operating voltage state of the compound lowered and increases the life of the compound becomes.
  • nickel-based alloy pipe nipples between the connection lines to the heating surface and the container wall of the Body installed and the pipe nipple welded directly to the container wall of the body so that an axial gap remains between the pipe nipple and the container wall.
  • the pipe nipples for connection to the connecting lines to the heating surfaces or Steam generator tubes of a steam generator made of a nickel-based alloy and inserted into the outer portion stepped connection bores in the wall of the container body and welded directly to the container wall, that between the pipe nipple and the bottom of the outer portion of the connection bore an axial gap remains.
  • the connecting lines to the steam generator heating surfaces of austenitic and therefore "white" material can be welded directly to the respective nickel-based alloy container pipe nipples whose coefficient of expansion between the coefficient of expansion of austenitic, d.i. white material, and the expansion coefficient of ferritic or martensitic, d.i. black material lies.
  • the pipe nipples made of a nickel-based alloy are welded directly to the container wall, so that the transition weld from the nickel base alloy of the pipe nipple to the material of the container wall is located directly at the transition from the container body to the container pipe nipple. Since the pipe nipple made of nickel-based alloy is inserted into the container wall while keeping an axial gap or free space between the pipe nipple and the container wall, a significantly better stress distribution results in the weld area.
  • Axial gaps between pipe end and wall are known per se from the ASME regulations (so-called ASME weld seams), wherein an insert is inserted between pipe end and wall, which is decomposed or destroyed during operation of the system, so that the axial gap remains. In this way, it is also possible to proceed when producing the welded connection according to the invention. However, it is also possible to keep open the axial gap acting as a kind of expansion joint in another way, e.g. by forming suitable projections or ribs or the like which are formed at the pipe end and / or the wall and are crushed during operation of the plant due to the expansion of the pipe nipple. The axial gap compensates for the elastic and plastic deformations of the pipe nipple.
  • the width of the axial gap is dependent on the difference between the pipe nipple and the container wall in their expansion behavior, which in turn depends in particular on the material used in each case.
  • the width of the axial gap is in the range of a few tenths of a millimeter to a few millimeters, e.g. at 1.6 mm before welding with a nipple outside diameter in the range of 40 to 80 mm.
  • the coefficient of expansion in the size range between the expansion coefficient of the nickel-based alloy from which the pipe nipples are made, and the expansion coefficient the material of the container wall is made of ferritic or martensitic material.
  • the nickel base alloys (e.g., Alloy 617) used as nipple material according to the invention are characterized by a coefficient of thermal expansion which is between the coefficient of expansion of ferritic or martensitic material and the coefficient of expansion of austenitic material.
  • a weld material whose expansion coefficient is in the size range between the expansion coefficient of the nipple material and the expansion coefficient of the material of the connection line is preferably used for the welded joint between the pipe nipple and the austenitic material connection pipe, or a welding material of a nickel-base alloy is also used.
  • a material for the main body of the collector or distributor serving container may also be used instead of a ferritic or martensitic material, a nickel-based alloy whose coefficient of expansion is in size between that of austenitic material and ferritic or martensitic material, wherein the pipe nipple made of a nickel-based alloy an expansion coefficient between that of austenitic material on the one hand and that of martensitic or ferritic materials on the other hand are made and welded directly to the container wall.
  • the container wall itself is made of a nickel base material
  • an axial gap kept free to compensate for the elastic and plastic deformation of the nipple during welding and especially in the Operation of the system is effective, although in this embodiment, the axial gap may possibly be smaller than a container wall of ferritic or martensitic material.
  • Another embodiment of the invention relates to a method for establishing a connection between steam generator heating surfaces made of an austenitic material and a container used as a collector or as a distributor with a base made of a martensitic or ferritic material, wherein nickel-based alloy pipe nip between the connecting lines leading to the heating surface be built of an austenitic material and the container wall of the body and the pipe nipples are welded at one end directly to the container wall and at the other end, each with a connecting line.
  • a welding material is used as the welding material for welding the pipe nipple and the container wall or the pipe nipple and the connecting line
  • the expansion coefficient is in the size range between the expansion coefficient of the nipple material and the expansion coefficient of the container material or the connecting line.
  • It can also be a welding material for welding the pipe nipple and the container wall and the pipe nipple and the connecting line are used, whose coefficient of expansion corresponds to that of the pipe nipple.
  • the welding material for welding the pipe nipples and the container wall may be different from that for welding the pipe nipple and the connecting pipe.
  • an axial gap between pipe nipple and container wall is kept free, which is effective for compensating the elastic and plastic deformations of the nipple during welding and in particular during operation of the system.
  • the nickel base alloy from which the container wall is made may be the same as that from which the pipe nipples are made.
  • Pipe nipples and container wall may both be made of Alloy 617, for example.
  • a material of a nickel-base alloy is also used.
  • nipple material and wall material are equal in coefficient of thermal expansion, a similar welding material is used. However, if these expansion coefficients are different, then preferably, a welding material having a coefficient of expansion between those of the nipple material and the wall material is used.
  • a welding material for welding the pipe nipples to the respective connecting line to the heating surface of the steam generator a welding material whose coefficient of expansion is in the size range between the expansion coefficient of the nipple material and the coefficient of expansion of the material of the austenitic connecting pipe is also used in this embodiment of the invention with a nickel-based alloy container wall or a nickel-based alloy weld material corresponding to the nickel-based alloy from which the pipe nipples are made is used.
  • the welding material for welding the connection lines to the pipe nipples may correspond to that which is also used to weld the pipe nipples into the container wall.
