Construction Health Law Optimization and Control
Start the installation, control students at this stage a very narrow specialized construction work, in order to avoid this period of slowdown, could be as follows: 1. Installation and inspection of materials for chemical production due process requirements for the different channels, there are a variety of materials and model specifications of the pipe, fittings, gaskets and valves according to the situation, according to the material form and the medium on the pipeline management process pieces of material requirements for classification column and make clear sign of investigation in order to avoid rejection of construction materials due to the wrong cause unnecessary rework. :. Advance the production of various processing components installed by the rejection of Health control Wangcheng An joints such as: transmitter connector, the temperature boss, pressure gauge and various middle connector and the connector end of the processing workload of the larger joints, which should be in advance the number of varieties of these joint statistics out of materials and specifications,[link widoczny dla zalogowanych], and to the materials processing sector 3. . Meeting ahead of the cable assembly and production of cable trunking trunking in particular the modular bridge sinks, a large number of assembly tasks and a variety of elbow, tee and other production tasks, and should therefore be made in advance 4. Out of the box in advance of arrival of inspection and testing instruments. Modern chemical production plant high level of automation, large number of various types of instruments, especially the larger number of control valve, control valve leakage inspection and grinding, a lot of work and commissioning the trip. Which should first arrange for the inspection and calibration of these instruments. 5. And pipes, pressure test equipment associated with blowing 38 * Chemical Construction Materials 1994 3 pieces of material processing required for the preparation of false purge process piping plate, blind flange opening remote transmitter board processing of parts of these materials to prepare in advance. . Second, the installation phase at this stage, the basic place Pat major equipment,[link widoczny dla zalogowanych], process piping, electrical installation Pat beginning to take shape, the Health Task control works also will be gradually increased. Therefore particular attention to the rational allocation of human and material resources in order to avoid slowdown. Should be the limited manpower and effective work group is divided into several units, expand the face, while the self-inspection and acceptance simultaneously with the installation, so installed a checkpoint to handle a point. Therefore, this phase should primarily as follows: 1. Equipment Yuan a component installation on the pipeline control engineering students are basically a device installed in the pipe and equipment, and scattered, and some time to take pressure port components and other plumbing fixtures can not be installed before opening, because some of the need for welded pipe testing and heat treatment. Therefore, the pipeline must be proud of a good place to take pressure before opening the mouth and the roots in the pipe after the valve is fitted in place, that is installed as a component synchronized with the pipeline equipment, but must be noted that applications for the Blind Flange seal; for the plate, the plate should be fitted with false} in regulating the use of a wider fiscal first short pipe connected with the specifications. The Department of trunking, cable through pipe, pressure pipe instrument protection box installation guide can be obtained in a pressure port positioning devices be installed in place, but the site should be considered the actual situation. 2. Instrument panel instrument panel installation and cable laying in place immediately after arrival, and then within the instrument panel wiring can be checked, this work can not be in the outdoor work to install, they must attack. Upon the completion of part of the on-site installation and cabling can be carried out on the wiring, and make marks. In addition to operating room instrumentation installation wiring debugging. Third,[link widoczny dla zalogowanych], the test phase 1. Purge and pressure test with the process pipe work required attention to the pressure test indicates pressure and leak testing instruments in place during the handling of the leak to work with. Pressure in the purge process guide also purge a clean tube,[link widoczny dla zalogowanych], to be clean after the blowing process piping, orifice, valves, flanges, transmitters and other instruments must be promptly reset. 2. Instrumentation System Joint Operation of the word and instrument installation and wiring is correct, you can debug the analog signal, check the instructions of various instruments, output, action is correct, can be put into operation after commissioning. , For signal and electrical interlocking professional, in addition to its own tune of Health Bin instrument control,[link widoczny dla zalogowanych], it must also meet the joint commissioning of electrical professionals to avoid errors. This construction method in Fujian Sanming Chemical Plant Health Control total investment of about ten million yuan expansion project of urea application to get a large extent, its application so that the whole project of the construction period of urine reasonable period shorter than ten months more to the project by Fujian Province as \Of course, this construction method of the implementation of the first officer on-site construction management high demands, asking them to read the students a comprehensive and detailed control of her professional construction drawings and data, carefully check the relevant construction documents, construction site conditions at any time changes to a reasonable arrangement of construction tasks, so as to proficiency in the complex arrangements for the construction site with limited human and material resources to achieve maximum conservation of materials and construction period.
