DN300 Flexible Flanged Metal Braided Hose
The DN300 Flexible Flanged Metal Braided Hose is a corrugated stainless steel hose with an outer braided reinforcement, designed to absorb vibration, compensate for thermal expansion, and reduce noise in high-pressure industrial piping systems. The hose has a nominal diameter of 300 mm and is fitted with carbon steel or stainless steel flanges for secure connection to rigid pipelines. It is engineered for applications in oil and gas, chemical processing, and HVAC where movement and stress relief are critical.
The hose body is made from stainless steel 304, with a braided outer layer constructed from high-tensile stainless steel wire. The braid can be single or double, depending on pressure rating, and is woven using 24 or 36 carrier constructions. The hose is bright annealed for ductility and corrosion resistance. The flanges are either carbon steel or stainless steel, welded directly to the hose ends. No internal lining is mentioned, indicating suitability for clean or non-corrosive media.
This hose is used by industrial plant operators, EPC contractors, and maintenance teams in sectors requiring flexible connections between pumps, compressors, and piping. Buyers typically order in quantities of 10 to 50 units per project. Packaging is in wooden crates with foam padding, and delivery is FOB Shanghai or Ningbo. Lead time is confirmed upon order. Certifications are not listed; buyers must request material test reports and pressure test certificates.

Sourcing DN300 Flexible Flanged Metal Braided Hose from Beijing Zhonghaiwei Environment Engineering Co. Ltd. - China Import Guide
Before ordering, request material test reports for both the corrugated tube and braid, confirming compliance with ASTM A312 and ASTM A270. Verify the flange grade and welding procedure. Ask for a pressure test certificate showing the hose was tested to at least 1.5x the intended working pressure. Do not accept generic declarations without documented proof.
Confirm Incoterms and lead time with the supplier. Delivery is typically FOB Shanghai or Ningbo, with lead times of 4 to 6 weeks after order confirmation. Packaging is in wooden crates with internal foam and rust inhibitors. Payment terms are usually 40% advance, 60% against shipping documents. Ensure the contract includes inspection rights before shipment.
Upon receipt, inspect the hose for surface defects, weld quality, and flange alignment. Measure the internal diameter and confirm it matches DN300. Perform a pressure test with clean water at 1.5x working pressure and observe for leaks or deformation. Retain samples of braid wire and flange material for lab analysis. Document all findings and retain packaging for return claims if needed.
