Frequently Asked Questions

What is the difference between ASTM A192 and A179?
ASTM A192 is specifically designed for high-pressure boilers, whereas A179 is typically used for heat exchangers and condensers. A192 has stricter wall thickness controls and mandatory heat treatment.
What types of inspections are performed on the tubes?
We perform various tests including Ultrasonic Testing (UT), Radiographic Testing (RT), Eddy Current Testing (ET), flattening tests, and flaring tests to ensure ductility and integrity.
What surface treatments can be applied?
Tubes can be supplied with black painting, varnishing, anti-corrosive oil, galvanizing, or bare surface according to customer requirements.
What is the standard delivery time for orders?
For inventory items, delivery is usually within 7-10 days. For custom production orders, the typical lead time is 15-30 days depending on the quantity.
Do you provide third-party inspections?
Yes, we support third-party inspections from reputable agencies such as TUV, SGS, BV, and IBR to meet global quality standards.
What are the available packing options for international shipping?
We offer wooden boxes, PVC bags, steel strips bundling, and plastic plate protection to ensure safety during sea or container transport.
