Why Choose ASTM A671 CC60 for Your Project
Selecting the right pipe material is crucial for long-term project success. The product offers distinct operational advantages.
This grade is specifically designed for pressure-containing systems where low-temperature performance cannot be compromised. The use of pressure vessel quality steel provides superior toughness compared to standard carbon steel pipe.
Electric fusion welding technology delivers consistent weld quality across the entire pipe length. The longitudinal weld seam incorporates filler metal to optimize joint efficiency and structural integrity.
Large diameter and heavy wall pipes are economically produced through the EFW process. This makes ASTM A671 CC60 Pipe a cost-effective alternative to seamless pipe for projects requiring sizes beyond typical seamless mill capabilities.
Manufacturing Excellence and Quality Assurance
Longma Group operates a 230,000-square-meter manufacturing facility equipped with advanced EFW production lines and heat treatment systems.
Our quality control process begins with careful selection of raw materials from reputable steel mills including Shagang, TISCO, and Bao Steel. Every steel plate undergoes chemical composition verification and mechanical testing before production.
The welding process follows qualified procedures with experienced welding personnel. Post-weld heat treatment is applied according to the specified class requirements—normalization and stress relief for Class 22 pipes significantly improve grain structure and impact resistance.
Non-destructive inspection involves 100% radiographic testing of the longitudinal weld seams for internal discontinuities such as porosity or absence of fusion. Hydrostatic testing is conducted at 1.5 times the design pressure to confirm structural integrity under service conditions.
Dimensional examination checks out of roundness and homogeneity of wall thickness. Installation ensures appropriate field alignment. Ultrasonic testing may be conducted on plate material, where required, to detect laminations.
Complete Documentation and Traceability
International engineering projects require comprehensive technical documentation for approval and compliance verification.
We provide complete Mill Test Reports according to EN 10204 3.1 standard, documenting chemical heat analysis and mechanical property verification with full traceability to the steel melt. Each pipe shipment includes Material Test Certificates with heat number identification, tensile and yield strength test results, elongation values, and low-temperature impact test data when required.
Radiographic examination reports, hydrostatic test records, and dimensional inspection certificates accompany every order. Third-party inspection by internationally recognized agencies such as BV, TUV, or Intertek can be arranged to meet project specifications.
Customized Fabrication and Surface Protection
Beyond standard pipe manufacturing, Longma Group offers value-added services to meet specific project requirements.
Fabrication services include welding, perforating, expansion processing, and specialized end treatments for connection systems. These capabilities allow us to supply ready-to-install components that reduce field labor and installation time.
Anti-corrosion protection options include hot-dip galvanizing, FBE coating, 2PP coating, 3LPE coating, and 3PE coating systems. Proper surface protection extends service life and reduces long-term maintenance costs in corrosive environments.

FAQ
Q:Why the product is a good option for low temperature pressure service application?
A：ASTM A671 CC60 is an electric-fusion-welded steel pipe manufactured from pressure vessel quality carbon steel plate, typically ASTM A516 Grade 60. Designed for use in applications requiring pressure resistance, low-temperature toughness and long-term durability. There are several important advantages of ASTM A671 CC60 from the buyer’s perspective: 1. Pressure vessel grade steel with good performance at low temperature 2. Mechanical properties are stable with pressure resistance 3. Large diameter and heavy wall ability with EFW manufacturing 4. Cost effective engineering solutions This grade offers a reliable solution for severe service circumstances for customers engaged in LNG facilities, petrochemical plants, power generation and industrial pipe systems.
Q：What quality requirements should buyers confirm when purchasing products?
A：A qualified manufacturer should provide Material Test Certificates with full heat number traceability, chemical composition analysis, and complete mechanical test reports including tensile strength, yield strength, elongation, and low-temperature impact test results when specified. Hydrostatic test records, weld examination reports including radiographic testing or approved non-destructive examination, dimensional inspection reports, and visual inspection records are essential. Depending on project requirements, buyers may also request heat treatment records, Positive Material Identification, additional weld inspection, and third-party inspection by internationally recognized agencies.
