Pushpak Steel & Engineering Co supplies Corten Steel Air Pre Heater (APH) tubes that meet ASTM A423 Grade 1 and Grade 2 requirements. The tubes are made from weathering steel, a low‑alloy alloy that develops a stable oxide layer, and are offered in standard lengths of 6 m and 12 m. Each tube can be ordered in a range of diameters from 50 mm to 200 mm with wall thicknesses between 3 mm and 10 mm, typical for heat‑exchanger applications. The product is packaged in bundled bundles suitable for container loading.
The weathering steel composition provides excellent resistance to atmospheric corrosion, reducing the need for repainting in harsh plant environments. Typical tensile strength for this grade is around 450 MPa and yield strength about 250 MPa, which aligns with industry expectations for high‑temperature service. The protective oxide film forms automatically when exposed to alternating wet and dry conditions, extending service life and lowering maintenance costs. These characteristics make the tubes a reliable choice for power‑generation and industrial combustion systems.
Primary users include power‑plant engineers, boiler manufacturers and firms that operate large‑scale heat‑recovery units. Pushpak offers flexible minimum order quantities and can ship under FOB or CIF terms from Mumbai. The supplier references ISO and SGS audits, but buyers should request current certificates before contract finalisation. Payment is typically secured through LC or T/T, and lead times should be confirmed for the required length and diameter.

Before placing an order, verify that the material grade matches ASTM A423 and request the most recent ISO or SGS audit reports. Confirm the exact diameter, wall thickness and length required for your heat‑exchanger design, and ask the supplier to provide a mill test certificate for each batch.
Logistics should be clarified early: agree on an Incoterm such as FOB Mumbai or CIF to a designated port, and obtain an estimated lead time based on the chosen dimensions. Discuss container loading plans and whether the bundled packaging meets your handling equipment specifications.
Implement quality controls by arranging a third‑party inspection at the supplier’s facility or at the loading port. Request non‑destructive testing results, visual inspection reports and the mill test certificate before shipment. Documentation of compliance will help streamline customs clearance and guarantee that the delivered tubes meet your performance criteria.
