The Cast Iron Exhaust Manifold supplied by Liaoning Borui Machinery Co., Ltd is a heavy‑duty exhaust component forged from gray iron (FC 200‑250) or ductile iron (SGI 400‑500). It is precision‑cast to fit high‑temperature engine exhaust systems in trucks, tractors and other agricultural machinery. The manifold is designed to withstand extreme exhaust temperatures and corrosive gases, providing reliable flow. Typical dimensions range from 800 mm to 1500 mm in length, with flange connections sized for 2‑inch to 4‑inch pipes.
Gray iron used in exhaust manifolds usually contains 2‑3 % carbon and a flake graphite structure that offers good thermal conductivity, while ductile iron provides higher tensile strength around 400 MPa. In the automotive sector, exhaust manifolds are commonly required to meet ASTM A536 or equivalent standards. The casting process includes post‑machining to achieve a smooth internal surface that reduces back‑pressure. These characteristics align with the expectations for heavy‑duty exhaust systems.
Primary users are manufacturers of heavy‑duty trucks, buses, agricultural tractors and industrial machinery who need durable exhaust routing. Buyers typically request FOB Dandong or CIF to their port, and may need wooden crate or palletised packaging for safe transport. Liaoning Borui Machinery Co., Ltd indicates ISO and SGS certifications are available, and offers flexible MOQ, though exact quantities should be confirmed directly with the supplier. The company can also provide material traceability certificates upon request.

Importers should obtain the full material test report that specifies the exact grade (FC 200‑250 or SGI 400‑500) and tensile strength of the manifold. Request the ISO 9001 and SGS inspection certificates to confirm that the casting process adheres to recognized quality standards. Verify the dimensional drawings, especially length and flange bolt pattern, to ensure compatibility with the intended vehicle platform.
Typical trade terms from Liaoning Borui Machinery Co., Ltd include FOB at the Dandong port and CIF to the buyer’s destination, but the precise Incoterm must be agreed before contract signing. Lead times are not listed publicly; ask the supplier for a production schedule based on order volume and any required post‑machining. Payment methods usually comprise T/T in advance, T/T after shipment, or a documentary letter of credit for larger consignments.
Arrange a pre‑shipment inspection by a third‑party agency such as SGS to verify material grade, tensile strength and surface finish. Upon receipt, conduct a visual inspection for casting defects and confirm that the packaging remained intact during transit. Retain all certification copies, test reports and inspection certificates for customs clearance and future maintenance records.
