Large diameter flanges and pipe assembly for attention and av
May 22, 2017
Large diameter flange and pipe assembly, need some strict requirements and detail, in order to ensure that the overall effect of the assembly, especially the sealing welding, so check the perpendicularity of the flange of the application of flange bending ruler.
Because in parallel and not exceed two flange requirements must be adjusted, in order to prevent or reduce the leakage of the flange joint surface, may not be used in the assembly is biased pad, multi-layer pad or use the method of strong bolt to avoid elimination of skewed.
The process of assembling is perfect when it comes to mastering every detail and accuracy, and you will be relieved when you use it.
Large diameter flange wear is a common cause of scrap mill design small reasonable ah lead to parts in the whole machine doesn't work, or any service life.
Measures to avoid serious wear and tear in large diameter flanges are mainly:
Rational design of the structure and size of mechanical parts to reduce the pressure and relative motion velocity between relative motion surfaces.
Selecting the right materials and heat treatment;
Adopting appropriate lubricants, additives and their supply methods;
When working under the conditions of pollution and dust, the necessary sealing or protective equipment shall be added.
Improve the accuracy of work and assembly to avoid local wear and tear.
It is necessary to use fluid pressure lubrication, fluid static lubrication, or use of magnetic buoyancy support, which can satisfy friction and wear extremely careful life long requirement.
In a word, only in large diameter flange and pipe connection grasp every detail, to improve the precision, the assembly process is successful, and to guarantee the overall quality of the project.
