Pipelines in pharmaceutical factories

2016-07-03View Original

Thread Content

Why are the pipelines in pharmaceutical factories welded from seamless tubes, rather than being assembled using prefabricated seamless tubes (at least that’s how it’s done in my factory)? This can reduce many unnecessary welding operations during subsequent maintenance.

Safety first! Your factory uses stainless steel filter elements, right? If you are capable of doing so, I hope we can work together!

Installation is a one-time process; in many cases, in an effort to speed things up, a pipe is welded all the way through, which results in the system being unable to be repaired or maintained once it’s installed. Even if the on-site management personnel request flanges to be added, the installers may skip this step out of laziness. After all, maintenance is not done by the installation team. This requires the personnel in charge of construction supervision to have extensive experience. I often do this; on construction sites, it’s common to first lay out the requirements, and any issues spotted are to be corrected on the spot. Even once something is done correctly, the construction party is still required to make further improvements.

What does LZ mean by seamless tube splicing – is it connected using flanges? In fact, the installation method for pipes depends mainly on the user and the designer. Generally, the connection between pipes and equipment is designed to be detachable, that is, via flange connections. Valves are usually used for shutting off or regulating flow. Therefore, even if other sections of the pipeline are quite long, welding is permitted unless the pipeline is prone to blockages and requires frequent disassembly and assembly. In installation work, this is often referred to as “on-site welding”; that is, most of the welds are prepared in advance according to the site conditions, with only a small number of welds that must be welded on-site being completed there. Unless the material used is of poor quality or the construction standards are low, the failure rate of pipes is relatively low. There is no need to add connection flanges unless there are specific requirements, as this will increase construction costs and create more potential leakage points.

I’ve learned it.* Thank you!! ~As I told you, it’s mainly for cost reasons and to reduce the number of leakage points.
