For urgent dimensional data, email mafuze@hebeiyagada.com with your required NPS / DN, pressure class, material, and quantity — our engineering team responds within 24 hours via WhatsApp or email with the exact dimension table.

Question 3

Are the spec sheets traceable to the issuing standard body?

Accepted Answer

Yes — every dimension, material value, and pressure-temperature rating in our spec sheets is sourced from the issuing standard body (ASME, EN, JIS, BS, HG/T) and cross-checked against the latest edition. Mill test certificates per EN 10204 3.1 are issued with every shipment.
