Common Questions
What standards do your seamless pipes comply with?
Our seamless pipes comply with API 5L (line pipe), ASTM A106 (high-temperature carbon steel), ASTM A53 (general-purpose), ASTM A335 (ferritic alloy), ASTM A312/A269 (stainless steel), EN 10216 (European pressure standards), and ASTM A519 (mechanical tubing). All products ship with EN 10204 Type 3.1 Mill Test Certificates.
What sizes of seamless pipe are available?
We supply seamless pipes from OD 21.3 mm (½") to 660 mm (26"), wall thickness 2.0–60 mm, in standard lengths of 6 m and 12 m. Schedules range from SCH 10 through SCH XXS. Custom dimensions are available with minimum order quantities based on grade and mill capability.
Are you a manufacturer or a trading company?
MetalFromTurkey is a B2B steel trading company and seamless pipe supplier — not a manufacturer. We source seamless pipes from API and ISO-certified partner mills in Turkey and internationally. This model gives buyers access to multiple production sources, competitive benchmarked pricing, and independent quality control.
What is the minimum order quantity for seamless pipes?
Standard minimum order quantity is 5 metric tons per product line. For combined orders across carbon, alloy, and stainless steel seamless pipes, we offer flexible split quantities. Contact our team with your requirement details for exact MOQ confirmation based on grade and dimensions.
How quickly can I get a quote for seamless pipes?
We typically respond to RFQ submissions within 24–48 hours for standard grades and sizes. Complex specifications involving multiple grades, non-standard dimensions, or special inspection requirements may take 3–5 business days as we collect offers from qualifying mills.
Can I order seamless and stainless steel pipes together?
Yes. MetalFromTurkey consolidates procurement across material categories — you can combine carbon steel seamless pipe, alloy seamless pipe, and stainless steel seamless pipe in a single order. Consolidated shipments reduce per-ton freight cost and simplify import documentation.
