After the steel lined pipe is delivered to the site, how can we identify the appropriate materials for each section of the pipeline? What markings should be made on steel-lined pipes? How do you find such a large amount of steel lining material on site?
A steel lined pipe isn’t it a standard fitting? Different lengths? Is it the diameter that’s different? Is it necessary to label?
1. Steel lining pipes are not standard general-purpose fittings. 2. The steel lining pipes are customized for specific operating conditions, with varying lengths and diameters. 3. It needs to be pre-installed before leaving the factory, and labeling is required.
The steel lining tube must be pre-assembled and qualified before being packed and delivered to the site.
After the steel lining pipe is properly pre-assembled prior to leaving the factory, it is labeled.
Sir, what I’d like to ask is: on the drawings, each pipeline is assigned a specific material code, but when the materials arrive at the site, they are all mixed together. How can we label or identify them so that we can quickly find the right materials on site, and avoid confusion or not knowing which one to use?
Before leaving the factory, it is pre-assembled according to the pipeline numbers specified in the drawings; during disassembly, it is numbered in sequence. The numbering principle varies from one factory to another, but it is generally based on a combination of letters and numbers – this is a basic requirement for factories when shipping products. As for the materials that arrive at the site, they are a mess without any labels or markings; you can ask the manufacturer to go to the site to resolve the issue or file a claim.
Is it necessary to assign a pipeline number to each pipe? Would that make it easier to locate them?
Each pipe segment has numbers at both ends.
