I would appreciate it if colleagues from engineering companies or design institutes could help answer this

To date, no specific guidelines have been issued in China for requesting quotes regarding the technology of complete sets of equipment used in chemical plants. Therefore, preparing a technical inquiry document requires relying on the company’s own technical requirements and standards, while also taking into account relevant domestic and international technical standards as well as industry experience. Generally, a technical quotation should include the following elements: 1. Basic information about the equipment, such as name, model, quantity, and main technical parameters ； 2. Technical and special requirements for the equipment, including material, operating pressure, operating temperature, corrosion resistance, etc ； 3. Main structural features and process flow of the equipment ； 4. Other relevant technical documents and certificates, such as quality assurance certificates, installation drawings, inspection reports, etc. It should be noted that when preparing the technical inquiry document, the technical and special requirements for the equipment should be described as thoroughly and comprehensively as possible, to ensure smooth subsequent procurement and installation of the equipment. Furthermore, technical inquiry documents should be prepared under the guidance of professionals, in compliance with **relevant laws, regulations, and technical standards, to ensure the rationality and feasibility of the design plan. .

There are no specific standard specifications for complete sets of equipment. For technical inquiries regarding complete sets of equipment, such as RTOs and flares, design and pricing are generally carried out in accordance with the SH standards or the industry-specific standards required by the client.
