Our manufacturing capabilities cover a comprehensive range of dimensions and configurations to meet diverse engineering requirements.

Why Choose Electric Fusion Welded Pressure Piping

Electric fusion welded pipes offer distinct advantages for large-scale pressure applications. The EFW manufacturing process creates consistent longitudinal welds with superior dimensional accuracy compared to traditional methods.

For projects requiring large-diameter heavy-wall piping, the product delivers economic benefits without compromising structural integrity. The fine-grain structure inherent in C60 grade material provides improved resistance to hydrogen-induced cracking in petrochemical environments.

Your procurement team will appreciate the practical balance between performance and cost. Unlike seamless alternatives that face manufacturing limitations at larger diameters, our EFW pipes maintain consistent quality across the entire size range. This consistency translates directly to reduced field welding complications and faster installation schedules.

Manufacturing Excellence and Quality Assurance

Longma Group's raw material is solely purchased from the first-class Chinese steel mills including TISCO, Bao Steel and HBIS. We maintain a strategic supply chain to guarantee that every quality plate for pressure vessels fulfils severe chemical composition standards before it enters our manufacturing line.

We have many quality control system check points throughout production. Heat treatment procedures improve weld zone qualities . Advanced NDT technology can identify small defects . All pipes are hydrostatically tested at 1.5 times design pressure to ensure leak-tightness under real service circumstances.

You'll receive complete documentation packages including Material Test Certificates with full heat traceability, radiographic inspection reports, mechanical test results, and dimensional verification records. Third-party inspection services from BV, TUV, or Intertek can be arranged to meet your project specifications.

Industrial Applications and Performance

Power generation facilities rely on our pipes for main steam lines and reheat piping systems where thermal cycling and sustained pressure demand exceptional reliability. The C60 grade maintains ductility and strength throughout temperature fluctuations inherent in thermal power operations.

These pipes are used in petrochemical refineries for distillation column interconnects and high pressure vessel pipework. The material’s resilience to deterioration throughout service makes it suited for applications where long term chemical exposure is encountered.

Our ASTM A672 C60 Pipe is used in compressor station installations and transmission infrastructure for midstream energy projects. The higher fracture toughness provides safety margins in critical pressure containment systems.

Value-Added Services for End-to-End Project Support

Besides our normal pipe manufacture, we also offer complete fabrication services to meet your installation needs. Our shops are able to weld, perforate, expand and provide unique end treatments to save you field labour expenditures.

Anti-corrosion protection increases service life in harsh situations. We provide hot dip galvanising, FBE coating, 2PP coating, 3LPE coating and 3PE coating under regulated circumstances to meet the criteria of adhesion and coverage.

FAQ

Q：Why is the product a reliable solution for high-pressure piping systems?

A：ASTM A672 C60 is an electric-fusion-welded carbon steel pipe manufactured from pressure vessel quality steel plate, typically ASTM A515 Grade 60. It is designed for high-pressure service applications where reliable strength, dimensional accuracy, and long-term performance are required. From your perspective as a buyer, this specification offers several practical advantages. The pressure vessel grade steel provides stable mechanical properties and dependable performance in pressure-containing systems. You'll benefit from a good balance between strength and toughness, sufficient for many industrial pressure applications while maintaining excellent fabrication characteristics. The EFW technology allows the manufacture of large diameter pipes, typically more economically than the seamless option. This is a good value, but not at the expense of quality. You obtain a sensible balance between technical performance and the entire project budget. This standard offers a reliable solution for power plants, refineries, petrochemical facilities and industrial plumbing projects where safety and long-term dependability are a must.

Q：What inspections should buyers require for the products?

A：For pressure piping projects, you should focus on quality assurance, weld integrity, and complete traceability to ensure safe long-term operation. A qualified supplier should provide Material Test Certificates with full heat number traceability, chemical composition analysis, and comprehensive mechanical test results including tensile strength, yield strength, and elongation values. Hydrostatic test records and weld quality inspection reports are essential. Radiographic Testing or other required non-destructive examination ensures weld integrity. Dimensional inspection reports and surface inspection records verify manufacturing precision. Depending on your project requirements, you may also request heat treatment records, impact testing at specified temperatures, and Positive Material Identification. Third-party inspection by internationally recognized agencies such as BV, TUV, or Intertek adds an additional verification layer. A professional supplier provides complete inspection documentation ensuring full traceability from steel plate to finished pipe.

Q：How can buyers choose a reliable product supplier?

A：Selecting the right supplier critically impacts product quality, project schedule, and operational reliability. Evaluate manufacturing capability first—look for proven experience producing EFW pipes, ability to manufacture your required dimensions, and experience with pressure vessel grade steel plate production. Quality management systems should include strict incoming material inspection, qualified welding procedures, experienced technical personnel, complete NDT and laboratory testing capability, and full manufacturing traceability. Project support capability matters significantly. Assess production capacity stability, delivery schedule reliability, technical response speed, and ability to provide customized inspection, coating, and documentation services. A trustworthy supplier provides more than standard-compliant products—they offer complete solutions that help you reduce risks and achieve smooth project execution.
