Sulfur- resistance,CO2- resistance, Nickel based alloyoil pipe
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.
