FAQ 1 - Dɛn ne chrome moly paipu grades a wɔtaa de di dwuma wɔ RFQs so?

RFQ dodow no ara de chrome-moly paw hyɛ ASTM/ASME grade mmusua te sɛA335 P5 / P9 / P11 / P22 / P91, afei wowie NPS, nhyehyɛe (fasu), ne tebea a wɔde bɛma a egyina piping class ne design temperature so.

FAQ 2 - Dɛn na ɛsɛ sɛ mekyerɛ na makwati mix-ups bere a meretɔ chrome moly seamless pipe?

Ɔmangrade + NPS + nhyehyɛe (anaasɛ WT pɛpɛɛpɛ) + delivery tebea + awiei awiei.
