【HaiChuan Pipeline Discussion】Is the floor construction in the boiler room carried out before or after the installation of the process pipelines in that area?

Why wait? It’s better to hand it over to the installation team after the civil construction is completed, right? Isn’t that a more civilized way of working?

1. For boiler pipes with a diameter of DN50 or less, drawings are generally not provided; the materials are cut to length on-site according to their layout； 2. Many of the pipes inside the boiler run underground ； 3. The floor in the boiler room is paved with tiles or self-leveling concrete, so it is usually installed at the end of the civil engineering work.

1. For boiler pipes with a diameter of DN50 or less, drawings are generally not provided; the materials are cut to length on-site according to their layout； --Why can’t a diagram be generated? Previously, it was due to issues with the design software; now that there is software available, it should be possible to do this, which will help reduce arbitrary decisions on site. As for the issues related to the contract drawings, they can be reported to the owner. 2. Many of the pipes inside the boiler run underground ； --Why go below? The underground pipelines can be installed first and then handed over to the civil engineering team for the floor work. 3. In boiler rooms, it is customary to use tile flooring or self-leveling floors; therefore, civil engineering usually handles this task last. --The floor can be left in its raw state first, then pipe installation is carried out, and finally the floor is finished as a whole

1. This is the rule of the Power Institute; it’s different from that of the Chemical Engineering Institute； 2. It is not an underground pipe; it is a pipe that connects the surface and the underground ； 3. It might be that the workers avoid crossing tasks out of convenience; it’s a matter of civilized construction.

The Chemical Engineering Institute requires drawings and material lists even for small pipes of diameter 4, whereas the Electrical Engineering Institute does not provide drawings for pipes with a diameter of DN50 or less; instead, the installation company prepares a material budget based on certain coefficients or fixes a lump-sum price. I once encountered a chemical engineering company that insisted on having a list of materials from the design institute, as it couldn’t start construction without it; the design institute, on the other hand, had no idea how to explain this situation, which was quite funny.

1. This is the rule of the Power Institute; it’s different from that of the Chemical Engineering Institute； ------------------------------------------ Actually, what’s most annoying about this is the idea that everyone has to follow certain rules. The Electric Power Institute still uses the old regulations, while the Ministry of Electric Power no longer exists at all

The power engineering institute can explain it this way: the company has no experience in installing power boilers, and it recommends that the owner choose another provider
