Pipeline branch

Pipeline branch, this product belongs to the special requirements of the pipeline branch, belongs to the customized product in the pipeline engineering, customized pipeline accessories. OEM.

Branch pipe joints where the angle between the branch pipe axis and the main pipe axis is less than 45°, or the branch pipe joint where the branch pipe axis and the main pipe axis do not intersect are all problems of special design and manufacturing. Such as tees, bifurcated pipes and crosses. The branch pipe and pipe fittings are connected by butt welding, socket welding, brazing, soft soldering, threaded or flange joints, or the branch pipe can be directly connected to the main pipe to form a socket welded right-angle branch pipe joint.

In general, the branch pipe is connected to the main pipe through custom-made pipe fittings or joints: and the branch pipe connection is designed, manufactured and inspected as a whole pressure component. If you want to connect the branch pipe directly welded to the main, it should meet the following requirements:

1 It is not suitable for use in parts with mechanical vibration, pressure pulsation, and rapid temperature changes, and pipelines where the juice temperature exceeds 425°C;

2 When the branch pipe connection is subjected to stress caused by the thermal deformation of the branch pipe, external load, and bracket displacement, the impact of the additional load on the branch pipe connection should be analyzed and necessary strengthening measures should be taken.

Common branch structures include integral pipe fittings, reinforced pipe joints, and welded branch pipes.

The integral pipe type branch structure is a type of pipeline branching using integral pipe fittings such as tees and crosses. Strengthening of customized pipe fittings joints is a type of pipe branching using special pipe fittings. This type is often used in situations that exceed the scope of the three-way or four-way branch, but it is often limited by the size of the branch. Under normal circumstances, socket welding or threaded connection is adopted.

The pipeline branch is a pipeline component that has multiple branch outlets and each branch outlet is provided with a valve that can divert the liquid or gas in the main pipeline to each branch outlet. In the current pipeline branch, the shunt pipe and each shunt ball valve are connected by bolts or welding. The product is easy to bump during transportation, causing cracks in the connection between the ball valve and the main pipe of the pipeline splitter; if the installer cannot install it correctly and accurately, it is very easy to cause cracks at the connection between the ball valve of the pipeline splitter and the main pipe of the pipeline splitter. , There is water or air leakage.

A pressurized water delivery system composed of pipelines in branch, parallel, series, etc. ways. The disciplines are water conservancy science and technology, hydraulics, river dynamics, coastal dynamics, and hydraulics. The water distribution pipe network is a pipe system that sends water to the distribution pipe network and even users. The layout of the water distribution pipe network includes a ring pipe network and a branch pipe network. The divergence, convergence and intersection of the pipe network all have strict requirements on size and elevation. It is very difficult to prevent pipeline fights and collisions, especially for some pipelines, once they are designed and adjusted. Unless the whole is rebuilt, the cost is staggering, so the design and production of the pipeline branch is very important.
