Hunan Standard Steel Co., Ltd supplies seamless steel pipe that complies with ASTM A106 Grade B and ASTM A53 specifications. The pipes are manufactured from carbon steel and are offered in nominal pipe sizes from ½ inch up to 48 inches NPS, with multiple schedule thicknesses. Each pipe meets the dimensional tolerances required for high‑pressure transport of fluids and gases. The product is marketed for export‑grade projects where reliability is critical.
The material grade provides a typical tensile strength of around 60 000 psi and a typical temperature service range of - 20 °C to 400 °C, matching industry expectations for carbon‑steel line pipe. Standard schedule 40 and 80 wall thicknesses are available, with a typical tolerance of ±0.1 mm on wall dimension. Surface finish is smooth to reduce flow resistance, a standard practice for pipe used in oil‑field applications. These characteristics align with the usual specifications for pipeline infrastructure worldwide.
Primary users include oil‑field contractors, EPC firms and utility companies that require seamless pipe for high‑pressure transmission. Trade terms are generally FOB from Chinese ports, with payment possible via L/C or T/T, and the minimum order quantity should be confirmed directly with the supplier. Lead time and packaging details are not disclosed in the listing and must be verified before placing an order. The supplier’s organic tier and harbor trust tier indicate a verified export capability, though response rates are currently listed as zero.
