Included activities starts

The boundary of production activities starts from the handling of the item under test.

Included activities ends

The boundary of production activities ends with the completion of the final product.

Description

This dataset describes the pressure testing of 1 kg of valve test items, resulting in the production of 1 kg of qualified finished goods. This dataset should be used together with the 1 kg of test items. The data inventory is compiled from multiple data sources and includes the main raw and auxiliary material consumption, energy use, and water emissions during the pressure testing process. Infrastructure such as production equipment manufacturing and factory construction is not included within the system boundary of the dataset.

Activity Description

This dataset represents the pressure testing process for 1 kg of valve test items, which should be used in conjunction with 1 kg of test items.

Process Description

The production cycle for common valves, such as gate valves, ball valves, globe valves, butterfly valves, and check valves, typically takes about three days. Manufactured valves must undergo various performance tests, among which the most critical is pressure testing. Pressure testing verifies whether the pressure value a valve can withstand meets the specified production requirements.
