Project | Requirements:
Applicable standard: ASTM A671 CL22 S2
Impact Test temperature: -45 °C (or -50 °F)
Test location: Weld centerline, heat-affected zone (HAZ), Base Metal
Energy absorption requirements: 14J min single / 18J min average
Heat treatment requires: Finished welded pipes be normalized.
Heat treatment object: The entire steel pipe (including welds, heat-affected zones, and base metal)
The purpose of heat treatment: To eliminate welding residual stress, refine grains and improve low-temperature toughness
The normalizing temperature for temperature control generally refers to the base material standard (such as A516 Gr.60), and is usually within the range of 850-950°C
Cooling method: Air Cooling

Packaging & Delivery
>Standard anti-corrosion oiling and pipe opening support
>The loading process is fixed by steel frames
>Provide third-party testing documents such as material certificate (MTC), radiographic test report, impact test report, etc
Application fields of ASTM A671 CC60 CL22 S2 42″ (1066.8mm) steel pipe
1. Pressure Piping at Moderate and High Temperatures
– Mainly used for conveying steam, water, oil, gas and other media
– The working temperature is generally in the range of room temperature to medium and high temperature
– Suitable for occasions with **moderate strength and good toughness**
2. Fossil Fuel Power Plant Piping
– Main steam pipeline
– Feedwater and condensate pipelines
– Economizer and superheater connecting pipes
– Bypass Systems
✅ Especially suitable for applications requiring medium and low temperature impact toughness (such as S2 low temperature – 45°C impact requirements).
3. Oil and Gas Transmission Lines
– High-pressure pipelines in oil stations
– Access sections of natural gas long-distance pipelines
– Pipeline connecting manifolds and valves in stations
– Tank inlet and outlet pipelines
Due to CC60 grade (base material A516Gr.60) has good weldability and toughness, so it is very suitable for systems with high reliability requirements in the oil and gas field.
4. Petrochemical and Chemical Applications
– Low and medium pressure pipelines in chemical plants
– Process piping systems
– Cooling water systems, heat exchanger pipelines
– Especially used under low temperature conditions (meet the impact requirements of –45°C)
5. Offshore Modules, Skid Systems
– Piping of auxiliary systems of offshore oil and gas platforms
– Low temperature and medium pressure piping on FPSO ships
– Skid Fabrications
– Usually **excellent resistance to low temperature brittle fracture** is required, and the S2 impact requirement is very important.
Why choose ASTM A671 CC60 CL22 S2 LSAW steel pipe?
1. Good composition: Base material A516 Gr.60, low alloy steel, easy to weld, good strength and toughness
2. Mature process: Double-sided submerged arc welding + overall normalizing, uniform structure, reliable quality
3. Reliable toughness: Meets –45°C impact requirements, suitable for cold areas and low temperature conditions
4. High economy: Compared with high alloy steel (such as 9Cr, Inconel), low cost
5. Strong versatility: Widely used in thermal power, oil and gas, chemical industry, shipbuilding and other industries
42″ (1066.8mm) large-diameter steel pipes are generally used for:
1. Main transmission trunk line
2. Large station communication pipeline
3. Boiler inlet and outlet main pipes
4. FPSO module large public piping
Testing requirements:ASTM_A671_CC60_CL22_S2_Spec
– 100% radiographic testing (RT)
– Qualified water pressure test
– Strictly control welding quality and low temperature toughness
– Standardized heat treatment process (CL22 requirements)
