ASME B16.5 Gr.2 Titanium neck butt welding flanges| Marine oil and gas·chemical·seawater desalination special corrosion resistant flange
Offshore oil and gas exploitation, fine chemical production, In severe conditions such as seawater desalination, Pipeline flange is the most vulnerable core component of the system, corrosion leakage, bolt load attenuation, seal failure and other problems, It is easy to cause equipment shutdown, repeated maintenance, High operating costs.
For complex working conditions of strong corrosion, high pressure, high vibration and large temperature fluctuation, our factory has launchedASME B16.5 Gr.2 Titanium alloy neck butt welding flanges (WN/RF)。The product integrates the excellent corrosion resistance and high specific strength advantages of pure titanium, Long-term pipeline seal stability and structural integrity, Significantly reduce the frequency of equipment maintenance, Effectively extend the overall service life of the piping system, It is a high-quality upgrade alternative to stainless steel flanges under high-end corrosion conditions.

Second, the core advantages of products
1. Super corrosion resistance, suitable for high salt and high corrosion conditions
Gr.2 Pure titanium is resistant to seawater, salt mist, wet chlorine gas, Organic acids, Chloride ion medium has excellent corrosion resistance, Pitting can be avoided effectively, crevice corrosion, intergranular corrosion and other common equipment failures, Corrosion resistance far exceeds 316L stainless steel, Perfect for marine and chemical strong corrosion scenarios.
2. Light weight, high ratio and strength, reduce pipeline load
Compared to traditional steel flanges, Weight reduction of approximately 45%, In safeguarding structural strength, under the premise of constant pressure performance, Significantly reduce pipe weight, Support loads and equipment load-bearing pressures, Especially suitable for offshore platforms, upper pipe gallery, Ship equipment, etc., under conditions where weight is strictly limited.
3. Stable operation in wide temperature range, adapting to complex temperature difference environment
Stable mechanical properties of products, Stable operation over a wide temperature range from low temperatures to 427 ° C (800°F), Capable of withstanding equipment start and stop, Seasonal alternation of cold and heat and frequent temperature fluctuations, Eliminate high temperature failure, Cryogenic embrittlement problems.
4. Excellent sealing performance to eliminate unplanned downtime
Necked butt weld construction, gentle stress transition, Pipeline alignment is neutral and accurate, With RF raised face seal design, Effectively buffer high pressures during equipment operation, influence of high frequency vibration, High sealing fit, strong stability, Reduce leakage failures at source, Reduce downtime maintenance losses.
III. Typical application scenarios
