6 FAQs about [Specification requirements for photovoltaic support welded pipes]

What are the requirements for welding a carbon steel pipe?

Welded joints should meet the requirements of a standard such as BS 2971 'Specification for Class II welding of carbon steel pipework for carrying fluids'. Welds should be inspected by an appropriate method depending on the application requirements. Radiography and ultrasonics are widely used where high integrity welds are required.

What welding guidelines should be followed for Cr-Mo steel pressure vessels?

The welding guidelines referenced in API 934-A, API 934-C, and API 934-E shall be followed for welding Cr-Mo steel pressure vessels for high-temperature, high-pressure hydrogen service.

What is a welding specification?

This specification provides requirements, supplementary guidelines and practices for welding and welding related topics for shop and field fabrication, repair and modification of the following: other equipment or component items when referenced by an applicable purchase document.

What are the requirements for gas shielded welding?

The weld and the area around it to a distance of at least 3.3 ft (1 m) shall be protected from inclement weather. The wind speed shall not exceed 0.5 mph (0.2 m/s) in the area where gas shielded welding (GTAW, FCAW-G, GMAW, PAW) is taking place. Acceptable welding processes are given in Table 7.

What are the requirements for a pressure retaining groove weld?

Test laboratories for mechanical, chemical and corrosion testing shall have a certified laboratory system in compliance with ISO/IEC 17025 for the test methods employed. Pressure retaining groove welds shall be full penetration. Except for piping, pressure retaining welds shall, where practical, be double sided.

What are the requirements for welding consumables?

The quantity of consumables in a single lot of SAW and ESW fluxes shall be in accordance with lot classification F2 defined in ASME BPVC Section II Part C or ISO 14344.
