Casing pipe、oil pipe are the necessary tubular product.Except the API standard product,we also fucos on developing the special materials oil casing .The materials include low-alloy steel, 13Cr martensite stainless steel, upscale ultratek; and the oil pipe product have gradually formed deep mine series, collapse-resistance series, sulfur- resistance serials,economical CO2- resistance serials and the combination of serials.
