STPG410 Material Properties and Pressure-Service Applications
STPG410 is a carbon steel pipe grade specified in JIS G3454 for pressure service at comparatively high temperatures. The grade requires a minimum tensile strength of 410 MPa and a minimum yield point of 245 MPa. Its mechanical properties make it suitable for piping systems conveying pressurized fluids, including industrial water, oil and other compatible process media, within the limits established by the system design. Material selection must account for operating pressure, temperature, corrosion conditions and required wall thickness. Although LSAW technology is suitable for producing large-diameter welded pipe, the selected manufacturing route, dimensions, inspection and acceptance criteria must be verified against the applicable edition of JIS G3454 before the product is specified.

Quality Assurance & Testing
Quality is controlled throughout the steel pipe manufacturing process at Huayang, from incoming raw material inspection to final product verification. Raw materials are sourced from established steel suppliers and undergo chemical composition analysis, mechanical property testing, and surface inspection upon arrival. During production, process controls and dimensional checks help ensure compliance with applicable standards and customer specifications. Finished pipes are subject to relevant inspections and tests, which may include hydrostatic testing, ultrasonic testing (UT), radiographic testing (RT), eddy current testing, dimensional inspection, and visual examination, depending on the product type and applicable requirements. Our testing facilities support quality verification at key production stages, while inspection records and quality documentation help provide traceability and confidence in product conformity.
Key Quality Control & Testing Capabilities
- Raw Material Inspection: Chemical composition, mechanical properties, and surface condition
- Non-Destructive Testing (NDT): Ultrasonic testing (UT), radiographic testing (RT), and eddy current testing, as applicable
- Mechanical Testing: Tensile, impact, hardness, and other tests as required by the applicable standard

Pipe Protection
Pipe-end protection is advisable in case the pipe-ends are bevelled at the pipe manufacturer. In the case of overseas transport, there is an especially increased risk of damaged pipe-ends. This is caused by extra handling procedures in ports and shifting of the pipes onboard vessels.
In addition to end caps or protective rings, external wrapping with protective cloth can be applied along the pipe body. This wrapping helps to safeguard the coating surface from scratches, moisture, and contamination during long-distance transportation or prolonged outdoor storage. Especially for coated or painted pipes, the additional protective cloth layer significantly reduces the risk of mechanical damage, UV exposure, and corrosion initiation, ensuring the pipes arrive at the destination in optimal condition.
Pipe Painting Services
In addition to pipe-end protection and external wrapping, Huayang provides customized steel pipe painting services to meet different project specifications and environmental requirements. Available options include water-based eco-friendly quick-drying paint, epoxy paint, quick-drying black paint, bituminous paint, and high-temperature-resistant paint. Paint type and application can be selected according to customer requirements, providing suitable surface protection for transportation, storage, and service conditions.
Steel Pipe Deep Processing
Beyond standard steel pipe manufacturing, Huayang provides customized deep processing services to meet different project and installation requirements. Our capabilities include flange welding, loose flange assembly, steel pipe piles, extra-long pipe joining, end beveling, and other fabrication services. Processing can be carried out according to customer drawings, technical specifications, and project requirements, helping customers reduce on-site fabrication work and improve installation efficiency.
