I.Titanium flangeWhat's that?speak it out in one sentence
Titanium flangeIs pure titanium or titanium alloy (TA1/TA2/TA9/TA10/TC4, etc.) as the raw material, the forging and precision machining forming of pipe fittings.Titanium flangeThe core function has two points: to realize the detachable connection between pipelines, reaction equipment and valves, and to ensure thatTitanium flangeReliable sealing of the connection position reduces the risk of medium leakage.
in chemical, Marine Engineering, nuclear power, Medical projects, Stainless steel flanges are difficult to operate stably for a long time under many severe corrosion conditions, chemical engineeringTitanium flangeWith excellent corrosion resistance, it is the preferred pipe connection for such harsh conditions.
Second,Titanium flangethe core advantages of
Many buyers will wonder,Titanium flangePurchase unit price is higher than 316L stainless steel flange, why is there still a large number of projects selectedTitanium flange?
resistant to dilute sulfuric acid, Dilute hydrochloric acid working condition, TA2 titanium flange can be used stably for 15-20 years, 316L stainless steel flanges usually only six months to two years will occur corrosion perforationface wet chlorine, hypochlorous medium, 316L flange will fail in a short time,
Titanium Flanges remain stable.Titanium flange weight is 40% lighter than stainless steel, with completely non-magnetic, excellent biocompatibility performance.
Although titanium flange purchase unit price is higher, but from the full life cycle cost accounting has more advantages.Titanium flange long service life, Reduce material costs and downtime losses due to multiple flange changes, Better overall procurement costs, It's ocean engineering., Titanium alloy flange optimized for strong corrosion condition of chemical engineering project.
Three, titanium flange 6 major mainstream brand selection points
Shaanxi Qianyi Tuoda has more than 3000 tons of titanium stock, Covers all mainstream
Titanium Flanges, Titanium flange grades can be quickly matched according to working conditions.
TA1 is pure titanium with purity ≥99.5%, suitable for
Titanium Flanges in weak corrosion environment, biological medicine and seawater conditions;TA2 Pure titanium purity ≥99.2%, Titanium flange belongs to chemical general brand, Titanium alloy flange is the foundation of the project selectionTA9 is Ti-0.2Pd titanium alloy flange, suitable for strong acid, strong reducing medium;TA10 titanium molybdenum nickel alloy titanium flange, for dilute sulfuric acid, dilute hydrochloric acid, wet chlorine scene;TC4 titanium aluminum alloy titanium flange, high strength, can withstand up to 400℃ working conditions;Ti-6Al-4V ELI ultra-low clearance TC4 titanium flange, mostly used for medical implants, deep diving and other high-demand scenarios.
Selection reference: hydrochloric acid, dilute sulfuric acid medium preferred TA10 titanium flange;TA9 titanium flange shall be selected for strong acid and pitting risk conditions;TA2 or TA10 titanium flange is optional for seawater desalination and offshore platform projects;Ti-6Al-4V ELI titanium flange is adopted for medical implantation and human body contact scenes;High temperature and high pressure, need high strength support choose TC4 titanium flange;Conventional chemical normal temperature and pressure conditions, TA2 titanium flange cost-effective outstanding.
Four, titanium flange 5 common structures
Purchase to get the drawings, first confirm the titanium flange structure type.
WN, titanium flange commonly used in chemical projects, high temperature and high pressure resistance;Welded flange SO neck used for medium and low pressure conditions, moderate cost, water treatment projects titanium flange widely used;Socket welding flange SW is suitable for small-diameter high-pressure pipeline, which is mostly used for titanium flange connecting instruments and valves;Threaded flange Th easy maintenance, not suitable for high temperature titanium flange;Loose sleeve flange LJ can be used with precious metal pipes, suitable for cost control projects using
Titanium Flanges.
Five, titanium flange six manufacturing processes
Understanding titanium flange production process can effectively avoid titanium flange quality risk in supplier docking stage.After raw materials enter the factory, Verification of Titanium Grade by Spectroscopic Analysis, Distinguish TA2, TA10 titanium flange material differenceForging is divided into free forging, die forging, ring rolling process, Free forging is suitable for special shapes, Large size titanium flange, Die forging suitable for mass production of titanium flanges, Large titanium flanges with diameter of more than 1 meter adopt ring rolling process.
5-axis CNC precision machining titanium flange sealing surface after forging, Control flatness ≤0.02mm, Surface roughness Ra≤1.6μm, Titanium flange sealing surface accuracy is not up to standard easy to cause field leakage.TC4 titanium alloy flange products need to be stress relief annealing treatment to avoid deformation after long-term use.Surface treatment Optional acid pickling sand blasting to remove titanium flange oxide layer, High wear resistance requirements can be micro-arc oxidation, Titanium flanges for pharmaceutical semiconductors under clean working conditions are electropolished.
Finished product quality inspection includes material spectrum verification, Ultrasonic and Penetrant Nondestructive Testing, tensile impact hardness mechanical test, Hydropneumatic or helium mass spectrometry seal test, Coordinate size detection.Each batch of titanium flanges can be accompanied by SGS and Pony test reports to support third-party re-inspection.For seal selection for titanium equipment, see
Six, titanium flange typical application scenarios
Chlor-alkali chemical scene medium is mostly wet chlorine gas, hydrochloric acid, sodium hypochlorite, TA10/TA9 chemical titanium flange, Service life up to 15-20 years, Performance better than 316L stainless steel, Long-term supply of Shaanxi, Henan (Province), Shandong many chlor-alkali enterprisesOcean Engineering and Seawater Desalination Project, Facing 3.5% concentrated seawater, Choose TA2 or TA10 titanium flange, Maintenance-free for more than 20 years, service Zhejiang, Fujian coastal seawater desalination projectPetrochemical hydrogenation conditions, high-temperature oil gas, hydrogen sulfide medium, Choose TC4 titanium alloy flange to resist high temperature and hydrogen embrittlementTA2 titanium flange is selected for nuclear power project, which is non-magnetic and anti-radiation corrosion, and the design life can reach 40 years;Ti-6Al-4V ELI ultra-low clearance titanium flange used in medical field;Hydrogen, semiconductor high-purity pipeline, choose anti-hydrogen embrittlement high-purity titanium flange, meet the requirements of high pressure and clean grade.
Seven, titanium flange implementation standards and specifications
GB/T 25198-2023 pressure vessel flange, NB/T 47023-2012 titanium butt welding flange technical conditions, HG/T 20592~20635 chemical European standard flange system;International common ASME B16.5 American standard titanium flange, ASTM B381 titanium forging standard, medical products to implement ISO 5832-3.Titanium flange pressure classes cover Class150-2500, PN0.6-PN42, titanium flange specifications DN10 to DN3000.
