Hi, need to submit a 1250 words paper on the topic Construction of a Reactor Vessel. Engineering department supplies to the Planning department, relevant documents viz., assembly, sub-assembly and detailed fabrication drawings and the corresponding bills of materials. Inspection, quality control and testing, both as per standard engineering practices, and as per the specific contractual conditions, are spelt out in these drawings. Planning department analyses the work and the procedures needed to complete the task, consolidates the list of raw materials and buy-out requirements, schedules the work for execution and releases the documents to the executing agencies. These agencies are generally the works manager, project manager, purchase manager, and the inspection and quality control manager. Once the work is taken up either in the Factory (off-site) or at the construction site (on-site), activities start with the material requisition/collection, preliminary inspection, and proceed through stages of Chemical vessels like reactors operate under arduous conditions like high pressures and high temperatures, involving dangerous liquids and gases. In view of the potential hazards to public health and safety, these types of equipment and their operations are controlled in a stringent manner through national and international codes of practice. Compliance to such standards is mandatory, right through all stages of manufacture of the types of equipment, and while operating them in a production process.
Chemical factories are usually located in remote areas in view of the potential pollution hazards. Construction work here often involves handling, transportation and installation of large-size equipment. Logistics play an important role in decision making whether to ship fully fabricated pieces of equipment or to carry out fabrication work at the site or to use a judicious mix of both.
