Steps of Pipeline Installation Engineering Installation

 

1.Steps
According to the elevation datum given by the civil engineering, mark the elevation datum line on the wall and foundation column where the pipeline needs to be installed; install the pipeline bracket and hanger according to the drawing and number; install the pipeline according to the pipeline installation drawing and the prefabricated number of the pipeline; Adjust and level the slope of the pipe, fix the pipe support, and position the pipe.


2.Request
The slope direction and gradient of the pipeline should meet the design requirements; the slope of the pipeline can be adjusted by the metal backing plate under the support, and the hanger can be adjusted by the boom bolt; the backing plate should be welded with the embedded parts or steel structure, It should not be caught between the pipe and the support.


Flanges, welds and other connecting parts should be arranged for easy inspection and repair, and should not be close to the wall, floor or pipe frame.


When the pipeline traverses the floor slab, a protective tube shall be installed, and the protective tube shall be 50mm above the ground.
When the pipeline traverses the floor slab, a protective tube shall be installed, and the protective tube shall be 50mm above the ground.
The form and elevation of the support and hanger should conform to the requirements of the drawings, and the fixing position and fixing method should conform to the design and be flat and firm.


Rows of horizontal or vertical pipelines should be neat, and the valve installation positions on the rows of pipelines should be consistent.

3.Installation
Pipeline installation is divided into systems and pieces. The main pipe first, then the branch pipe. The branch pipe from the main pipe should be installed after the main pipe is positioned. Century Star introduced that the pipeline connected to the equipment must be carried out after the equipment is leveled.


The flange connection should be concentric with the pipeline, and the flanges should be parallel. The deviation should not be more than 1.5% of the outer diameter of the flange and not more than 2mm. The bolt holes should ensure that the bolts can penetrate freely, and the bolts should not be penetrated by forced methods. .


The two planes of the gasket should be flat and clean, and there should be no radial scratches.


Flange connection should use bolts of the same specification, and the installation direction should be the same. When gaskets are needed, each bolt should not exceed one, and the bolts and nuts after tightening should be flush.
