Hello! Our company is interested in regular purchasing of seamless carbon steel pipes. Standard - API 5CT or GOST-R 633-80 (K,E); length 9,5-10,5 m, external diameter 73 mm, wall thickness 5,5 mm. We need 5-7 wagon per month, maybe more (300-400 tons). Transportation by railroad, possible in 2 variants: 1) DDP to the station Podvoloshnaya (Russia), code 781803; or 2) DAF to the station Alashankou (China), code 3300019. Payment - letter of credit. If you are interested in further cooperation, please send me copies of production certificates, on my e-mail. Both API and GOST-R certificates would be great. Also please give me prices of pipes including transportation in two variants, as I wrote earlier. Best regards, Danil Andreev +79122905079 danandreev@mail.ru
