Chapter 6

The Resource Requirements for Manufacture Licensing of Safety Appurtenances


Article 59

Basic requirements

1. The applicants for safety appurtenance manufacture licensing must have business license or have registered in relevant local governmental departments where the manufacturer is located.

2. The safety appurtenance manufacturer should have working site, workshop, related manufacturing equipment, and inspection and testing facilities suitable for production of its products.

3. The safety appurtenance manufacturer should keep a sound and an effective management system for product quality. The main links for safety appurtenance production, such as, design, material, welding, NDE, machining, heat treatment, pressure test, product inspection, metrology, etc. shall have relevant responsible personnel in order to assure that the product quality accord to the requirements of the relevant Chinese codes and standards for safety appurtenances. The requirements on quality management system are specified in the Chapter 4 of these Requirements.

4. The safety appurtenance manufacturer should have all the technical staff that meets the demand of design, material, purchasing products, machining, welding, NDE, type testing and quality management of safety appurtenances and the percentage of the technical staff should not less than 5 per cent of all its employees. Among them, the manufacturer must have enough welder, welding operators, and NDE examiners, the quantity and qualified items of them should be suitable for product production.



Article 60

Specific requirements for manufacture licensing of safety valves

1. All types of the safety valve applied for manufacture licensing must have passed type testing.

2. The manufacturer shall have warehouse with enough areas suitable for sorted storage of semi-products, purchasing products with different types and sizes, such as, valve body, bonnet, springs, etc.

3. The manufacturer shall have the facilities with required function and accuracy and suitable for safety valve production, such as, lifting appliances, transporter, NDE equipment, drying and temperature keeping ovens for welding consumables, welding surfacing facilities and machining tools etc.

4. The manufacturer should have furnaces for spring heat treatment, processing and testing facilities for the compression strength of spring.

5. The manufacturer should have lapping machine and the devices for surface quality examination suitable for safety valve production.

6. The manufacturer should have measuring tools suitable for dimension measurement of the parts and components of safety valves.

7. The manufacturer should have facilities for hydrostatic pressure testing and leak testing suitable for safety valve production.

8. The manufacturer should have adjusting and testing set pressure branches suitable for safety valve production.

9. The spring-loaded safety valve manufacturer shall have testing branches for whole items of safety performance testing. The manufacturers producing other than spring-loaded safety valves should have corresponding performance test devices suitable for their produced safety valves.

10. The manufacturer should have apparatus for determining chemical compositions and for mechanical property testing of materials.



Article 61

Specific requirements for manufacture licensing of bursting discs and bursting disc devices

1. All types of the bursting discs and bursting disc devices applied for manufacture licensing must have passed type testing.

2. The manufacturer shall have presses, and material cutting, forming and slotting facilities suitable for the requirements for bursting disc production.

4. The manufacturer should have machining tools with suitable accuracy and laser cutting machine which meet the requirement of bursting disc production.

5. The manufacturer shall have NDE detectors suitable for product manufacture.

6. The manufacturer should have measuring tools suitable for dimension measurement in production.

7. The manufacturer should have facilities for hydrostatic pressure testing and leak testing suitable for the production of bursting disc devices.

8. The manufacturer should have both ambient-temperature and elevated-temperature bursting pressure testing devices suitable for the products manufactured.

9. The manufacturer should have apparatus for determining chemical compositions and for mechanical property testing of materials.



Article 62

Specific requirements for manufacture licensing of gas cylinder valve

1. All types of the gas cylinder valves applied for manufacture licensing must have passed type testing.

2. The manufacturer shall have warehouse with enough areas suitable for storage of raw material, accessory materials, parts provided by subcontractors, purchasing products and parts, and the end products.

3. The manufacturer should have specific forging machines, machining tools, threaders, lifting appliances and transporter suitable for product manufacture.

4. The manufacturer should have devices and apparatus for product type testing and for other inspection and testing items, such as, opening and closing moment gauge, devices for leak testing, anti-vibrating testing, heat-resisting testing, pressure testing, durable testing, safe relieving device testing and vacuum testing, etc.

5. The manufacturer should have test apparatus for determining chemical compositions and mechanical properties of valve body materials.
