Article 595:A sales contract is a contract in which the seller transfers the ownership of the subject matter to the buyer and the buyer pays the price.

Article 596: The contents of a sales contract generally include the name, quantity, quality, price, time limit, place and method of performance, packaging method, inspection standards and methods, settlement method, words used in the contract and its effect, etc.

China's existing laws and regulations related to pressure vessels and safety technical specifications include "Regulations on Safety Supervision of Special Equipment" and "Pressure Vessel Management System".

The design unit of the pressure vessel shall be licensed by the special equipment safety supervision and management department before it can engage in the design activities of the pressure vessel.

The design unit of the pressure vessel shall meet the following conditions:

1. There are designers and design reviewers who are suitable for the design of pressure vessels;

2. There are places and equipment suitable for the design of pressure vessels;

3. There is a sound management system and responsibility system that is compatible with the design of pressure vessels.

The design documents of gas cylinders (hereinafter referred to as gas cylinders), oxygen cabins and passenger cableways, large-scale amusement facilities and high-energy-consuming special equipment in boilers and pressure vessels shall be identified by the inspection and testing institutions approved by the safety supervision and management department of special equipment before they can be used for manufacturing.

Article 22 of the Pressure Vessel Management System shall be comprehensively inspected and tested before the pressure vessel is put into use under one of the following circumstances:

1) Pressure vessels that need to be restored after being out of service for more than two years (referring to those that have been used);

2) Pressure vessels that have been used and transferred from external units;

3) Change the use conditions, or exceed the original design parameters and pass the strength check of the old pressure vessel;

4) The user has doubts about the safety status of the pressure vessel.

Article 6 The main responsibilities of the equipment department are as follows:

1) Implement the "Regulations on the Safety Supervision of Special Biyou Equipment" and the relevant pressure vessel safety technical specifications, rules and regulations;

2) Supervise the operation and maintenance, inspection and inspection of pressure vessels and safety devices of each unit;

3) Responsible for the registration, archiving and management and statistical reporting of technical data of containers;

4) Participate in the investigation, analysis and reporting of container accidents, and inspect the implementation of accident prevention measures;

5) often go deep into the use of the site, check the use of pressure vessels, master the technical status of the pressure vessels of the enterprise, solve the problems in the use of management, and continuously improve the management level of the enterprise;

6) Responsible for the inspection and evaluation of the use and management of pressure vessels, timely summarize and promote advanced experience, praise the advanced, and criticize the backward;

7) Responsible for the purchase, acceptance, installation and commissioning of pressure vessels and contact the outsourcing unit to inspect the expired equipment.

Summary. Hello dear, the definition of a simple pressure vessel is:

The design pressure is less than or equal to, the volume is less than or equal to 1000L, the product of the working pressure capacity and the container is greater than or equal to, and less than or equal to 1000MPa, and the medium is water vapor formed by evaporation of air, nitrogen and medical distilled water. The design temperature is greater than or equal to -20, and the maximum operating temperature is less than or equal to 150.

At present, according to the national regulations, the gas storage tank below 10 kg per cubic meter is a simple pressure vessel and does not need to be inspected and the gas storage tank with more than 10 kg per cubic meter needs to be inspected by the relevant departments before it can be installed and used. Hope it helps.

The new regulations on the definition of simple pressure vessels are verified there.

Hello, the definition of a simple pressure vessel is: the design pressure is less than or equal to, the volume is less than or equal to 1000L, the product of the working pressure capacity and the vessel is greater than or equal to, and less than or equal to 1000MPa, and the medium is air, nitrogen and water vapor evaporated from medical distilled water. The design temperature is greater than or equal to -20, and the maximum operating temperature is less than or equal to 150.

At present, according to the national regulations, the gas storage tank below 1 cubic meter of 10 kg is a simple pressure vessel, which does not need to be inspected and is purely slippery, and the gas storage tank of more than 10 kg of 1 cubic meter needs to be inspected by the relevant departments before it can be installed and used. I hope I can help you.

Summary. Hello dear<>

The volume and pressure standards of pressure vessels vary according to the regulations and standards of different countries and regions. In China, the volume and pressure standards of pressure vessels are regulated by the Regulations on Safety and Technical Supervision of Pressure Vessels.

What is the volumetric pressure standard for pressure vessels?

Hello dear<>

The volume and pressure standards of pressure vessels vary according to the regulations and standards of different countries and regions. In China, the volume and pressure standards of pressure vessels are stipulated in the Regulations on Safety and Technical Supervision of Pressure Vessels.

According to the regulations, the volume of pressure vessels is divided into the following three categories:1Large Pressure Vessels:

A pressure vessel with a volume greater than or equal to 10m in content. 2.Medium Pressure Vessel:

Pressure tolerant resplicator with a volume greater than or equal to 1m but less than 10m. 3.Small Pressure Vessel:

The line shouts a pressure vessel with a volume of less than 1m.

According to the Regulations on Safety and Technical Supervision of Pressure Vessels, the design pressure of pressure vessels must meet the following standards:1Large Compact Sakura Power Container:

The design pressure must be greater than or equal to the medium-sized pressure carrying force vessel: the design pressure must be greater than or equal to the small and wide pressure vessel: the design pressure must be greater than or equal to.

In addition, pressure vessels need to meet other safety requirements and standards, such as material strength, welding quality, air tightness, explosion safety and other <>
