❓ Frequently Asked Questions
What standards do your precision steel tubes follow?
Our tubes meet international standards including DIN 2391, EN 10305-1, EN 10305-4, ASTM A519, and JIS G3445, ensuring compatibility with global engineering requirements.
What are the available delivery conditions for these tubes?
We offer various delivery conditions to suit different applications: BK (+C), BKW (+LC), BKS (+SR), GBK (+A), and NBK (+N) for bright annealing and normalized finishes.
Which industries primarily use your HYT-1 carbon steel tubes?
The HYT-1 model is widely used in automotive powertrain systems (fuel rails, diesel lines), hydraulic and pneumatic pressure lines, construction machinery, and heat exchange systems.
How do you ensure the quality of the seamless steel tubes?
We perform 100% Eddy Current testing along with 100% size and surface checks. Other tests include tensile strength, yield strength, chemical analysis, flattening, and flaring tests.
What size ranges can you provide?
Our standard size range covers Outer Diameters (OD) from 2mm to 60mm and Wall Thickness (WT) from 0.1mm to 10mm. Custom lengths up to 6m or per request are available.
Are your products certified for marine or aerospace use?
Yes, our steel tubes and forgings are suitable for demanding fields including Marine, Aerospace, Oil & Petrochemical, and Power Generation, with certificates according to EN 10204 3.1.
