I am looking to source API Steel pipes that meet specific requirements for our upcoming project. We need seamless pipes with a certain diameter and thickness, particularly with a length of 12 meters. The specifications are crucial for our operation, and we also require pushing coupling sockets to complement these pipes efficiently. Please provide your pricing, availability, and lead time for the requested items. Additionally, any relevant details regarding material certifications, testing, and quality assurance would be appreciated. We aim to finalize our procurement decision soon, so timely responses will be beneficial. Thank you!
