Abstract

The invention discloses a pipe clamp for a nuclear power steam generator U-shaped pipe. The pipe clamp comprises an upper circular arc groove, a lower circular arc groove, upper clamping grooves, upper side walls and lower clamping plates, wherein the upper clamping grooves are formed in the two sides of the upper circular arc groove, the upper side walls are arranged between the upper clamping grooves and the upper circular arc groove, and the lower clamping plates are located on the two sides of the lower circular arc groove. The pipe clamp for the nuclear power steam generator U-shaped pipe is simple in structure, convenient to manufacture, good in effect of fixing the U-shaped heat transfer pipe and capable of preventing damage caused by movement or mutual collision in the process of transportation and storage, and the transportation efficiency of the U-shaped pipe is improved.

Description

technical field [0001] The invention relates to the technical field of heat transfer tubes for nuclear power steam generators, and more specifically relates to a pipe clamp for U-shaped tubes of nuclear power steam generators. Background technique [0002] The Chinese invention patent with the patent publication number CN 103146959 A and the publication date of 2013.06.12 discloses a U-shaped seamless nickel-chromium-iron alloy heat transfer tube for nuclear power steam generators. Its chemical composition is: ≥58% Ni, 28 -31% Cr, 8-11% Fe, 0.01-0.03% C, ≤0.5% Si, ≤0.5% Mn, ≤0.01% S, ≤0.015% P, ≤0.05% Cu, ≤0.016% Co, ≤0.5% Ti, ≤0.5% Al, ≤0.1% Nb, ≤0.003% B, ≤0.05% N; the invention adopts hot-extruded nickel-chromium-iron alloy tube billet After multi-pass cold rolling deformation, online degreasing, pure hydrogen protection continuous bright heat treatment and vacuum heat treatment, the surface quality and dimensional accuracy of the straight pipe are ensured. At the same t...
