Problems solved by technology

[0008] In the natural compensation, the corner of the pipeline, that is, the elbow of the pipeline is used for compensation. The elbow needs to be made separately as a pipe fitting. Although the cost of the elbow is lower than that of the compensator, due to the addition of elbows in the pipeline, Increase the resistance of the fluid in the pipeline, resulting in poor circulation of the fluid in the pipeline and reducing the circulation efficiency of the pipeline

Abstract

The invention discloses an uncompensated pipeline component. The uncompensated pipeline component comprises a plurality of pipelines; the pipelines are connected and welded end to end in sequence; the axes of adjacent pipelines are not in the same straight line; an included angle is formed between adjacent pipelines. According to the technical scheme of the invention, thermal compensation of the pipelines is completed by welding the pipelines at certain included angles; the pipelines are connected by welding, so that the construction process of the pipeline connection is simplified; a compensator and an elbow are not required to be arranged on the pipelines additionally, so that the cost of pipeline construction is reduced.

Description

technical field [0001] The invention relates to a pipeline assembly and a manufacturing method thereof, in particular to a non-compensated pipeline assembly and a manufacturing method thereof. Background technique [0002] The current method used to solve the thermal elongation of pipelines is mainly to add compensators, supplemented by natural compensation. [0003] The use of compensator compensation is to install a compensator at the joint of the pipeline. The cost of the compensator is high, and the construction cost is relatively high. In addition, it is necessary to pre-design the compensator frame and other supporting settings during the construction process, which increases the workload and reduces the cost. construction efficiency. [0004] Pipeline natural compensation, commonly used natural compensation methods are L type and Z type. [0005] The L-shaped pipe compensation is composed of a long arm pipe and a short arm pipe. The short arm and the long arm are co...
