Abstract
Abstract A quench system for pipes in which jet streams of quench liquid are directed against only the outside surface of an open ended pipe as it passes therethrough. The jet stream nozzles are designed to deliver solid jet streams and are arranged in parallelly spaced apart and coaxially disposed annular groups. The nozzles of each group are directed so that the axes of their jet streams lie in a single plane that is perpendicular to the pipe axis. The axes of the jet streams of each group are also uniformly and adjustably offset or angled with respect to radial lines extending from the pipe axis. The jet streams of a planar group become confluent on the surface of the pipe and the confluent portion has centrifugal components of force which induce the quench fluid to separate from the surface of the pipe. This arrangement enables the spent quench fluid to be expelled through the space between the planes of the incoming jet streams without accumulation of quench fluid from non-adjacent planes. A barrier may be provided ahead of the first group of liquid jet nozzles to limit the frontal flow of quench fluid.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
178 words
A pass through quench system unit for pipe comprising: means for supporting said pipe and conveying it lengthwise along a designed horizontal axis of travel through said unit in addition to rotating said pipe about its longitudinal axis, said quench unit having a plurality of elongated quench fluid supply manifolds extending parallel to said axis of travel and equally spaced in a circle therearound, a plurality of orifice members disposed along each of said manifolds and arranged with respect to each other to provide a series of spaced apart coaxially disposed annular groups of orifices lying in planes perpendicular to said axis of traveL, said members being designed to project solid streams of quench liquid within said planes and in the general direction of said axis of travel, whereby the jet streams impinging upon the surface of the pipe from each adjacent pair of annular groups counterbalance each other to prevent flow in axial directions along the pipe, and means for moving said orifice members in unison to adjust the projected direction of said streams within said planes.
Claim 2
Dependent Claim
