FAQ
Q: Q1: What is the maximum temperature this SCH40 ERW pipe can handle?
A: For standard ASTM A53 Grade B SCH40 ERW pipe, the maximum continuous working temperature is up to 425°C, which is fully suitable for low-pressure steam, hot water and general industrial fluid transportation.
Q: Q2: Can you provide third-party inspection before shipment?
A: Yes, we fully support SGS, BV, LR or any other appointed third-party inspection organization to carry out dimension check, material test and visual inspection in our factory before loading.
Q: Q3: What is your standard package for export?
A: Normally pipes are bundled with steel strips, then wrapped with waterproof woven plastic cloth on the outside. Special packaging requirements can be negotiated according to client's demand.
