JIS G3454 Carbon Steel Tubes
JIS G3454 carbon steel pipes are applied for pressure‑bearing working conditions with a maximum service temperature of 350℃. Where higher pressure performance is required, pipes complying with JIS G3455 should be considered. This product can be supplied as seamless or electric‑resistance welded steel pipe, and purchasers are entitled to specify whether hot‑finished or cold‑finished condition shall be adopted.

JIS G3454 Carbon Steel Tubes STPG370 STPG410 Seamless & Welded Pressure Steel Pipe
Product Overview
JIS G3454 carbon steel pipes conform to the Japanese industrial standards for pressure piping. Seamless and electric‑resistance welded carbon steel pipes are available. STPG370 and STPG410 are common grades. These pipes exhibit consistent mechanical properties and have relatively good weldability. They are often used for boilers, heat exchangers, pressure vessels, and industrial fluid transport working under medium and high‑pressure conditions.

Optional surface finishes include black paint, varnish coating and anti‑corrosion treatment. Tube ends are provided as plain ends or bevel ends, as agreed on each project. We can tailor dimensions, surface finish and end caps to meet diverse project requirements.
Each production batch shall complete full required inspections including dimension check, tensile test, flattening test, flaring test and visual inspection. Every tube shall undergo hydrostatic test or non‑destructive electric examination. Under hydrostatic test condition, pipes shall withstand specified pressure without leakage. Test parameters can be adjusted based on tube dimension and project standards. Test records are reserved for traceability and can be delivered with mill test certificates. Third‑party inspection is acceptable upon customer request.
Core strengths
Choose the plan that suits you best.
1. Reliable Material Consistency
We screen raw steel materials carefully before production. All incoming steel meets JIS and ASTM standard requirements. Steady chemical and mechanical properties keep material deviations to a minimum for pressure‑bearing pipeline projects.
2. Diversified Customization Support
We adjust tube sizes, surface finish, pipe marking and end protection based on real‑world project needs. We handle both regular sizes and non‑standard special specifications, offering practical processing solutions for different working conditions.
3. Strict Batch‑wise Quality Control
Every production batch goes through full‑range checks including dimension measurement, mechanical tests and visual inspection. Any defective goods will be sorted out during production, reducing potential risks for end‑site use.
4. Complete Document & Service Support
Mill test certificates are available for every order. We accept third‑party inspection from SGS, BV and other institutions. Our team offers pre‑order technical advice and keeps clients updated on shipment progress.
