Second, the core advantages of products
1. Titanium steel composite structure, greatly reducing engineering costs
The contact surface of medium is pure titanium material, which can completely resist chloride ion, seawater, organic acid and strong corrosion medium.Loose flanges can be used with carbon steel/stainless steel.Compared to allTitanium flangeThe pipeline scheme greatly reduces the overall cost, especially suitable for large-diameter and large-batch pipeline projects, and the cost reduction effect is remarkable.
2. Free rotation structure, field installation and maintenance more efficient
360° free rotation of lap joint with loose flange, No alignment required Pipe angle, Field bolt hole alignment is simple and fast, extremely low altitude, at sea, Installation difficulty of complex pipe rack.At the same time, it supports repeated disassembly and assembly, and adapts to industrial pipelines for high-frequency maintenance and cleaning.
3. TG/RJ double seal structure, suitable for high pressure, high temperature and high risk conditions
Different from common RF convex surface seal, TG tongue groove surface seal precision is high, anti-off, sealing stability;RJ ring connection surface adoptsMetal to metal hard sealconstruction, Can withstand high temperatures, high pressure, severe pressure fluctuations, Prevent medium leakage, volatilization, Combustible and explosive, Strong corrosion high-risk medium pipeline, Higher seal rating, Safer operation.
4. Full grade titanium coverage, accurate matching under all working conditions
Covers Gr1 high plastic materials, Gr2 general purpose corrosion resistant material, Gr5 high strength titanium alloy, Gr7/Gr12 High-end corrosion resistant titanium, according to sea water., acid-base medium, high temperature and high pressure, Accurate selection of mechanical loads and other different working conditions, Considering formability, Strength and corrosion resistance.
III. Typical application scenarios
-
industry of fine chemicals: strong acid, chloride, corrosive medium transmission pipeline, solve stainless steel corrosion leakage problem
-
seawater desalination projects: long-term seawater immersion, high salt spray environment, pitting resistance, crevice corrosion resistance, prolong equipment cycle
