In the construction of pipeline steel pipes, the design and use of end braces is a very critical link. The main function of the end brace is to ensure the stability of the end of the pipeline steel pipe, prevent the deformation and misalignment of the nozzle, so as to improve the construction quality and safety.
The design of the end brace mouthpiece needs to take into account factors such as the specification, material and construction environment of the pipeline steel pipe. In general, an end brace consists of a support plate, a fixture, and an adjustment device. The support plate is used to bear the weight and pressure of the nozzle, the fixture is used to fix the support plate on the nozzle, and the adjusting device can adjust the position and angle of the support plate according to the actual situation. 
During the construction process, the construction personnel need to install and adjust the end brace mouthpiece in strict accordance with the design requirements. First, make sure that the support plate fits snugly to the nozzle to prevent gaps or misalignment. Second, make sure the fixtures are firm and reliable to prevent them from loosening or falling off. Finally, the adjustment device should be adjusted according to the actual situation to ensure that the position and angle of the support plate meet the design requirements. 
In addition to reasonable design and firm installation, the use of end braces also needs to pay attention to the following points. First of all, it is necessary to regularly check the status of the end brace mouthpiece, and deal with abnormal situations in time. Secondly, it is necessary to avoid stacking heavy objects or other construction operations on the end brace. Finally, after the construction is completed, the end brace should be removed in time and maintained and maintained for the next use. 
To sum up, the end brace has an important role in the construction of pipeline steel pipes. In order to ensure the quality and safety of construction, we need to reasonably design, correctly install and standardize the use of end braces.
