俄罗斯采购需求：Ba（光亮退火）管、Ep（电解抛光）管、超高压管、仪表管、高精度管、高纯度管

We are looking to procure chemical tubes suitable for pumping 35% nitric acid, specifically for use in our plant construction. The quantity needed is significant, and we would also require various connections to complement the tubes. Could you please provide a detailed price list at your earliest convenience? We're planning to handle this procurement through our company based in China, so any relevant shipping information would also be appreciated. Thank you!
