For some key equipment, the design requirements (such as material selection and material inspection requirements, etc.) often involve the material major. Therefore, the above equipment drawings should generally be submitted to the material major for review. The selection of materials for general equipment is based on the engineering material selection regulations, and there are fewer special problems related to materials in the design, so this type of equipment drawings generally do not need to be submitted to the material major for review. 3.3 Review of the technical quotation of the manufacturer (commercial)
Reviewing the technical quotation of the manufacturer (commercial) is an important task of this major. This major should make a technical evaluation of the technical quotation of the manufacturer (commercial) together with the material major (mainly for key equipment). When several manufacturers (commercial companies) offer quotations for the same equipment (set) at the same time, this specialty should complete the technical evaluation table and evaluation opinions of the manufacturer (commercial company) quotations, and submit them to the person in charge of this specialty and department for review in accordance with the requirements of HG/T20701.4-2000 Design Quality Assurance Procedure, and then hand them over to the design manager, who will send them to the purchasing department as the basis for the purchasing department to decide on the manufacturer (commercial company) to order the equipment (set).
3.4 ​​Manufacturer Coordination Meeting
The Manufacturer Coordination Meeting (VCM) is held for key equipment and is an important meeting to discuss and decide on the design, material selection, manufacturing, inspection and other related issues of the equipment with the manufacturer (commercial company). The meeting is mainly prepared by the container and heat exchanger professionals and they participate in the entire process of the meeting from beginning to end. Before the meeting, the engineer and professional person in charge of the equipment design should prepare the detailed agenda (technical part) of the meeting according to HG/T20701.12-2000 "Working Procedures and Instructions for Coordination Meetings of Professional Manufacturers of Containers, Heat Exchangers and Special Equipment" and draft an invitation letter to the manufacturer. During the meeting, records should be kept and the meeting minutes should be sorted out (technical part). Other relevant professionals can participate at any time according to the progress of the meeting and the content of the discussion. The relevant materials and inspection parts in the meeting minutes can also be sorted out by the relevant professionals and then incorporated into the technical part of the meeting minutes. For general equipment orders, the professional designers should also participate when necessary and be responsible for discussing and deciding relevant technical issues with the manufacturer (merchant). Under normal circumstances, it is not necessary to form a separate minutes, and the discussion results of relevant technical issues can be used as a supplementary clause in the order contract.
3.5 Order version of equipment schematic (equipment engineering drawing) and/or data sheet The order version of equipment schematic (equipment engineering drawing) and/or data sheet is carried out after the factory (commercial) coordination meeting (VCM) of the equipment and before the signing of the order contract. It is an important part of the technical attachment of the order contract. The relevant agreement reached by the VCM should be reflected on this version. Generally, some supplements and modifications will be made to the inquiry drawing through VCM or when ordering equipment. Therefore, in the case of many changes to the inquiry version of the drawing, it is necessary to publish a new version of the drawing (i.e. the order version) as the formal basis for ordering. 3.6 Review of the advance confirmation (ACF) drawings
The advance confirmation (ACF) drawings are the drawings provided in advance by the manufacturer according to the requirements of the order technical documents. The drawings are signed by the relevant personnel at all levels of the manufacturer (design, verification, and audit). The review of the ACF drawings is generally undertaken by the designer and verifier who completes the equipment schematic (equipment engineering drawing) of this specialty. This work should be carried out in accordance with HG/T20701.6-2000 "Key Points for Review of Drawings of Container and Heat Exchanger Professional Manufacturers". 3.7 Manufacturing version equipment schematic (equipment engineering drawing) The manufacturing version equipment schematic (equipment engineering drawing) is a work that this specialty begins after receiving the ACF drawings of the manufacturer (commercial) and reviewing them. In addition to the need to supplement and modify some graphics and data in this version of the drawing, the supplementary design conditions provided by the relevant professions during the detailed design process should also be supplemented, such as the orientation of the pipe mouth, the orientation and elevation of the support, the supporting structure or reinforcement plate to be pre-welded on the equipment, and the position of the fixed support of the horizontal container or heat exchanger. In addition to being distributed to the relevant disciplines within our company (institute), this version of the drawing should also be sent to the manufacturer as a basis for the manufacturer to complete the final confirmation (CF) drawing. 3.8 Review of the final confirmation (CF) drawing
The final confirmation (CF) drawing completed by the manufacturer is the final drawing delivered by the manufacturer to the production workshop for manufacturing. For the sake of prudence, our company (institute) still needs to conduct a final review to ensure that the manufacturer's drawings fully meet the order requirements. 12
3.9 Construction version equipment schematic (equipment engineering drawing) The construction version equipment schematic (equipment engineering drawing) is made after this specialty receives the CF drawing from the manufacturer (commercial) and is not expected to make any further modifications. If the equipment needs to be modified for some reason before manufacturing (it can only be carried out after obtaining the approval of both the buyer and the seller), these modifications should be reflected in the construction version of the equipment schematic (equipment engineering drawing). If no modifications or changes are made to the manufacturing version, just note "for construction version" in the modification column and sign the date, which means that the construction version has been issued. Table.
