How to entrust the pressure vessel design unit to carry out the design

Fill in the "Design Power of Attorney", the drawings belong to the external documents, should fill in the "Design Document Review Record", and then prepare the "Main Pressure Element Process Flow Card", "General Pressure Component Process Card", "Pressure Test Process Card", "Leakage Test Process Card", "Heat Treatment Process Card", "Welding Process Specification" and other process documents, and then fill in the corresponding records in real time in the manufacturing process**, these are specified in detail in the "Quality Assurance Manual", and all kinds of ** are also in a controlled state, There is a certain format, if the evidence is obtained, "quality assurance manual", "procedure documents", "process code", "work instructions", "post responsibility system" and various forms and cards must be made first, and then implemented according to this provision. You can follow the requirements of Circular No. 22 and No. 194 and TSG Z0005-2007 and TSG Z0004-2007. Your question is too much to complete.

In accordance with the design control procedure, entrust a design unit to design a pressure vessel (corresponding design qualification, such as A1, the other party must have A1 design qualification), and the corresponding requirements such as environment, pressure level, and basic size of the vessel should be mentioned in the commission. According to your parameters, the other party will help issue a corresponding level of design drawings, our company is also collecting evidence, we are asking Liaoyang Petrochemical Machinery to design, you can find them first and then talk about it in detail, the other party agrees to do it according to the procedures.

This requires the process, design, materials, welding and other responsible persons to review the drawings, process countersigning, this countersigned document to be used as a witness point, to see during the on-site inspection, in addition to this, there are many witness points, but the most important ones are:

The first is to do the welding evaluation, remember this offer to invite the supervision and inspection bureau to come, they want to see the welding evaluation of the material, the material certificate, and the material on the supervision and inspection of the steel seal, 2, the head, this also to supervise, if the head is outsourced, to outsource the manufacturer to issue a supervision certificate, 3, hydrostatic test, air pressure test, this is also to be supervised,

It depends on what kind of pressure vessel is designed. If it is D1 or D2 level, most of the relevant pressure vessel design training courses are held by the local provincial technical supervision bureau, which is authorized. Once you pass the exam, you will be eligible for the audit.

If it is an A-class pressure vessel design, you should participate in the training course organized by the National Standardization Committee and obtain the corresponding audit qualifications, and you must also be a senior engineer.

The relevance is as follows. The design and manufacturing unit of the pressure vessel must be qualified. The projects I have been in contact with, the design institutes are all general contractors, and the pressure vessel design institutes inside are all mature products purchased from outside, if the design institute designs the pressure vessel by itself, then it must be qualified.

Pressure vessel (yā lì róng qì), English: pressure vessel, refers to a closed equipment that contains gas or liquid and carries a certain pressure. In order to more effectively implement scientific management and safety supervision and inspection, China's "Pressure Vessel Safety Supervision Regulations".

According to the working pressure, the hazard of the medium and its role in production, the pressure vessel is divided into three categories.

And each type of pressure vessel in the design, manufacturing process, as well as inspection items, content and methods have made different provisions. The pressure vessel has implemented the safety and quality licensing system for imported goods, and the goods that have not obtained the import safety and quality license are not allowed to be imported.

It should be divided in accordance with the latest TSG21-2016 "Safety Technical Supervision Regulations for Fixed Pressure Vessels", first divided into the first group of media and the second group of media according to the medium, and then divided into categories according to the pressure and volume of the class, class, class, the so-called first, second and third categories of the old regulations are no longer applicable.
