[Sichuan] Workshop Process Pipe and Equipment Installation Construction Scheme (Luban Prize)
Content introduction This manuscript is the construction scheme for the installation of the process pipeline of the silk making and package making, the process power pipe network and equipment installation of the cigarette production line in a cigarette workshop in Sichuan; The construction scope of the project includes water pipes, compressed air pipes, steam pipes, condensate recovery pipes, negative pressure pipes, sewage pipes, dust removal pipes (including process dust removal, environmental dust removal and screening dust removal), and moisture discharge pipes for all equipment supporting the silk making and rolling; Purchase and manufacture of cables and bridge materials behind the power cabinet, as well as materials and standard parts of finished pipe supports and hangers; Manufacturing of process and power pipe network system; Unloading, relocation and initial positioning of power station room, water pump room equipment and supporting equipment; Cooperate with the joint commissioning of the production and operation of the joint workshop; Pipeline construction process: 1. General industrial pipeline construction process and process construction preparation - → cooperate with civil engineering to reserve and embed - → survey and set out, draw a sketch - → support and hanger installation - → pipeline rust removal - → paint, anti-corrosion (stainless steel pipeline degreasing treatment) - → blanking, groove - → main/main pipe prefabrication, welding - → main/main pipe hoisting, assembly Welding - → branch pipe assembly and welding - → crater treatment - → hydrostatic test - → system flushing - → anti-corrosion joint coating and insulation - → trench backfilling - → system connection. 2. Steam pipeline installation construction process and process construction preparation - → cooperate with civil engineering reservation and embedding - → measurement - → support and hanger installation - → pipe rust removal - → paint, anti-corrosion - → blanking, groove - → main/main pipe prefabrication, welding - → main/main pipe hoisting, assembly, welding - → branch pipe assembly Welding - → NDT - → hydrostatic test - → system flushing - → anti-corrosion joint coating and insulation - → paint - → pipe heating - → steam purging - → pipe trench backfilling - → system connection. 3. Compressed air pipeline installation construction process and process construction preparation - → reservation and embedment - → surveying and setting out - → support and hanger installation - → pipeline pretreatment - → blanking, groove - → main/main pipe prefabrication and welding - → main/main pipe hoisting, assembly and welding - → branch pipe assembly Welding - → NDT of welds - → pipeline strength test - → leakage test - → flushing and purging - → system commissioning - → system connection.
