Hebei Senhaipipeline Co., Ltd. supplies plate flanges made from carbon steel and stainless steel grades 304 and 316 for a broad range of piping systems. The products conform to ANSI B16.5 and ASME standards and are offered in nominal sizes from ½ in to 24 in, corresponding to bore diameters of 21.3 mm to 3000 mm. The catalogue also lists a variety of material specifications such as A105, ST37.2, S235, A350LF2, C22.8, S400, SQ235, A694, 304L and 316L.
In the oil‑ and gas, petrochemical and water‑treatment sectors, plate flanges are typically selected for pressure classes up to Class 150 (PN 10) and for temperatures ranging from - 20 °C to 350 °C. A standard 2 in nominal flange, for example, has a thickness of about 0.75 in (19 mm) and uses an eight‑hole bolt pattern with a bolt circle diameter defined by the nominal size. Stainless‑steel versions provide enhanced corrosion resistance, while carbon‑steel grades are chosen for cost‑effective high‑pressure applications.
These flanges are purchased by project engineers, procurement officers and EPC contractors who need reliable connections for pipelines, valves and equipment. Importers should be aware that the supplier offers flexible packaging for containerised shipment and can supply both FOB and CIF terms. Because the listing does not disclose minimum order quantities or lead‑time, buyers are encouraged to discuss these details directly with the supplier to align with project schedules.

Importers should first verify that the flanges meet the required pressure class and material certification for their project, requesting mill test reports and, if needed, a CE or equivalent conformity declaration. Checking the exact nominal size, bolt‑hole pattern and temperature rating against project specifications will avoid costly re‑work later. It is also prudent to confirm that the supplied material grades match the design data sheet supplied by the engineering team.
Logistics typically involve loading the wooden‑crate‑packed flanges at the Tianjin or Qingdao ports under FOB terms, although CIF options can be arranged. Because the listing does not disclose lead‑time, buyers need to ask the supplier for a production schedule and any minimum order quantity. Payment is commonly made by T/T in advance or by irrevocable LC, often tied to the presentation of shipping documents.
Upon arrival, a third‑party inspection should check the flange dimensions, bolt‑hole geometry and material markings, and compare them with the mill test report. Requesting a non‑destructive testing certificate, such as ultrasonic or radiographic inspection results, can further assure quality for high‑pressure applications. Proper customs documentation, including the commercial invoice, packing list and any required export certificates, will facilitate smooth clearance.
