巴基斯坦采购需求：碳钢无缝管，管道供应商，CS 管，MS 管，Apl 5l 无缝管，HDG 管

I'm looking for a bore casing pipe with a total length of 1100 feet. Could you provide me with your available sizes, specifications, and any relevant details about the product? Additionally, I'm interested in understanding the material composition and any certifications that come with it, as those factors are important for my project. Could you also let me know about your pricing, lead times, and minimum order quantities? If you have any samples or product catalogs, that would be great too. I'm keen on establishing a solid partnership, so any terms regarding bulk purchases or long-term agreements would be helpful for my planning. Looking forward to your prompt response!
