In project management for new chemical projects, how can the installation of process pipelines in tank areas be managed effectively? What aspects should be considered to control the quality during the installation of process pipelines? This post was last edited by laiqi on 2009-3-4 15:48]
I. Master and strictly implement the relevant specifications and standards； II. There is a detailed construction plan that is strictly followed ； III. Choose a construction team with extensive experience in construction work ； IV. Areas of attention: pipe material, cleaning before pipe installation, welder certification, welding procedure qualification, TIG welding for root pass, appropriate electrode material, welding quality, heat treatment, hydrostatic testing, airtightness testing, etc.
Follow the relevant regulations strictly – there’s no way of getting it wrong! If the construction team is not good, replace them; if the construction methods are inadequate, change them. Ensure strict quality control, and 99% of the time there will be no problems. .
In place! Just because the contractor can secure projects does that mean they have the capability to do a good job? Is it really worry-free? No, well, it is necessary to include reward and penalty clauses in the contract. Strict control over materials and personnel on site is of utmost importance; there must be no negligence! Strengthen the control of machinery, environment, and process discipline. There should be no worries either
Attention must be paid to the impact of tank settlement on the pipelines; during purging, ensure that no debris is blown into the tanks, and be mindful of areas within the pipelines where liquid may accumulate
Great reminder! There are many large storage tanks and column reactors within the facility, and their completion and settlement do not occur at the same time, which causes many difficulties with piping. We encountered projects with highly specialized civil engineering work, where the foundations suffered from significant settlement, which caused many difficulties in scheduling the piping work. . . How do you plan the piping schedule?
The contractors don’t have the capability, but they still take on projects! If the project cannot be completed by the deadline, he delays things; if it fails to meet the acceptance standards, he has it redone…. None of this matters really. The most important thing is for the construction party to win over the client’s supervisors. As soon as the project is finished, those in charge make their money – as long as the project meets its functional requirements, who cares about its lifespan!
The construction team can’t just be replaced whenever there are problems; working on a project doesn’t mean that teams can be changed at will, as that would cause chaos in the project； Therefore, before bringing in a team, it is necessary to first understand their construction qualifications and experience; tests for special types of work must also be conducted prior to starting the construction. The construction method must be carefully considered, taking into account past successes and failures; first, its feasibility must be determined, and it can only be used if it is proven feasible. But the entire construction method cannot be changed just like that. On the premise of ensuring safety, quality is always the top priority.
Based on LS, two additional points: 1. Pay attention to strengthening the protection of finished and semi-finished process piping! Because the protection of finished and semi-finished products may seem like a minor matter, if it is not done properly or thoroughly, it can easily cause significant problems during the subsequent cleaning and purging of the piping system. 2. Pay attention to strengthening the classified management of pipeline materials! For reference!
Piping in the tank area is very important; it is essential that the route of the pipes complies with the requirements outlined in the drawings. However, many workers, seeking convenience for their own installation, alter the pipe routes without authorization, resulting in pipe intersections that cause a lot of trouble during subsequent modifications and expansions.
Apart from the insightful remarks on the 2nd and 9th floors, what are some other key technical aspects to pay attention to in the process installation of tank areas? I would appreciate it if you could provide a detailed explanation. Thank you
