C&N Industiral,huitong limtied is professional pipe,flange and fitting manufacturer,our products approved by PDO, SADARA, SWCC,PDO etc.
Recently, C&N Group successfully completed batch production of ASME B16.49 seamless bends for a steel project of an Saudi Arabia customer. The products include 22.5°, 45° and 90° bends, all with a bending radius of 8D, made of API 5L GR.B PSL2 (X241). All bends have now entered the final inspection and packing stage. Dimensional, hardness and chemical composition re‑checks are being carried out to ensure all products are defect‑free and meet the stringent requirements for high‑pressure transmission fittings.

In fields such as long-distance pipelines, oil & gas, and high-pressure fluid transmission, piping systems often face multiple harsh conditions including high pressure, low temperature, and sour media, etc. Under such extreme environments, selecting proper and reliable pipe fittings is directly critical to the long‑term safety and operational cost of a project.
About API 5L Grade B PSL2
API 5L Grade B PSL2 is a carbon steel line pipe material fully compliant with API 5L and ISO 3183 industry standards. It delivers a minimum yield strength of 35,500 psi (245 MPa) and a minimum tensile strength of no less than 60,200 psi (415 MPa).
Unlike standard carbon steel bends, PSL2 grade enforces far stricter controls on harmful impurities: phosphorus (P) is capped at ≤0.025% and sulfur (S) at ≤0.015%. It also requires mandatory impact toughness testing at 0°C (longitudinal ≥41 J, transverse ≥27 J) and 100% non-destructive testing (NDT) for every product. These enhanced requirements drastically lower the risk of low-temperature brittle fracture and welding cracks, making this material ideal for demanding operating conditions including high-pressure systems, sour media service, cold climates, and offshore environments. With a design service life exceeding 30 years, it delivers long-term reliability for critical pipeline projects.
At the same time, C&N Group applies premium manufacturing processes for this batch of bends: normalizing heat treatment delivers a uniform, fine-grained structure to significantly enhance corrosion resistance, while the outer surface is protected by a dual system of black anti-rust paint and hot-dip galvanizing, effectively resisting chloride ion corrosion and sulfur-bearing oil/gas media erosion. These API 5L Gr.B PSL2 ASME B16.49 seamless bends are securely packed in sturdy wooden cases with protective cushioning, ensuring safe transportation and storage for global pipeline projects.
For operators seeking bends that ensure the structural integrity of long-distance pipelines under harsh conditions—preventing deformation and leakage—ASME B16.49 API 5L Gr.B PSL2 seamless bends are the trusted solution. As a leading Chinese manufacturer of line pipe bends, C&N offers a full range of specifications and material grades to meet diverse project needs.
