Frequently Asked Questions
Seamless tubes offer higher pressure-bearing capabilities and uniform structural integrity because they lack a longitudinal weld, which is often the weakest point in high-temperature and high-pressure environments.
For superheaters, alloy steels like T11, T22, and especially T91 are recommended due to their exceptional creep strength and oxidation resistance at elevated temperatures.
Yes, our tubes are manufactured to meet major international standards including ASTM and ASME (e.g., SA213, SA335), and we provide full traceability and Mill Test Certificates (MTC) for PED compliance.
Our pressure vessel tubes typically range from 10 mm to over 200 mm in outer diameter, with customized sizing available to meet specific engineering requirements.
We utilize advanced dimensional control processes to guarantee strict tolerances on outer diameter (OD), wall thickness (WT), and ovality, ensuring an optimal fit for tube sheet assembly.
Absolutely. We offer a variety of stainless steel grades including TP304/304L, TP316/316L, TP321, and TP347H, specifically optimized for corrosion resistance in chemical plants and refineries.
