Steel strip flange is a commonly used component for pipeline connections, consisting of two identical flanges and a galvanized steel strip in the middle. This design makes it easy to install, has good sealing performance, and strong load-bearing capacity, and is applied in fields such as petrochemicals, water engineering, and construction engineering. The installation process is simple, just combine the flange and steel strip and tighten them with bolts. In addition, the sealing performance of the steel strip flange is excellent, which can effectively prevent leakage and ensure pipeline safety.

petrochemical industry
A pipeline used for transporting oil and gas, as well as chemical raw materials, capable of withstanding high pressure (up to 25MPa) and corrosive media.
construction work
Suitable for high air volume (≥ 10000m ³/h) and vibration environments in air conditioning ventilation ducts and fire sprinkler systems.
water supply engineering
Connect buried water pipelines to prevent interface leakage caused by soil pressure.

Material selection
Stainless steel: made of 304/316L material, suitable for marine environments or chloride ion corrosion scenarios.
Galvanized steel: hot-dip galvanized layer thickness ≥ 80 μ m, meeting general industrial anti-corrosion requirements.
Carbon steel+coating: spray epoxy resin, balancing cost and rust prevention.
manufacturing process
Steel strip forming: High frequency resistance welding is used to ensure that the steel strip has no weld defects.
Flange processing: CNC machine drilling with hole spacing accuracy of ± 0.1mm.

High pressure scenario (>10MPa): Choose welded steel strip flange with neck and add socket structure.
Frequent disassembly: using a loop type steel strip flange, supporting over 100000 cycles of assembly and disassembly.
Low temperature environment (below -50 ℃): Made of austenitic stainless steel material to avoid cold brittle fracture.
