Product Description

I. Product Introduction The titanium alloy long high-neck flange for pressure vessels is a long high-neck welding flange manufactured according to national/American standards for pressure vessel flanges. It is made of pure titanium or titanium alloy forgings through integral forging, CNC precision machining, and non-destructive testing. It is specifically designed for use with various titanium pressure vessels, reactors, storage tanks, heat exchangers, and towers.

1. Structural Features

It adopts an extended tapered high-neck structure, with a long neck, smooth transition, high rigidity, and strong resistance to deformation; It is butt-welded to the pressure vessel shell and head, resulting in uniform stress distribution and minimal stress concentration; Sealing surfaces are optional: convex face RF, concave-convex face MFM, tongue and groove face TG, and ring joint face RTJ, suitable for high pressure, high temperature, and strong corrosion sealing; It is integrally forged without splicing, meeting the pressure vessel requirements for pressure bearing, airtightness, flaw detection, and safety compliance; Specifications cover: DN50～DN2000, pressure ratings PN10～PN160, Class150～Class2500.

II. Main Application Areas

1. Chemical Pressure Vessels: Various titanium-material reactors, stirred tanks, distillation columns, extraction columns, heat exchanger tube boxes and flanges; suitable for highly corrosive conditions such as acetic acid, nitric acid, chlor-alkali, fine chemicals, and pesticide intermediates.

2. Seawater Desalination and Marine Engineering Pressure Vessels: High-pressure vessels for seawater desalination, seawater heat exchange pressure vessels, offshore platform buffer tanks, and flanges for pressure vessels used in subsea operations; resistant to seawater corrosion and marine salt spray.

3. Pharmaceutical, Biological, and Food Industry Pressure Vessels: Pharmaceutical fermentation tanks, bioreactors, sterile storage tanks, and food concentration pressure vessels; requiring high cleanliness, no heavy metal leaching, and resistance to acid and alkali disinfection.

4. Environmental Desulfurization and Denitrification Equipment: Power plant desulfurization absorption towers, waste liquid treatment pressure vessels, and exhaust gas purification tower equipment flanges; resistant to sulfur- and chlorine-containing corrosive media.

5. New Energy and Nuclear Power Supporting Vessels: Electrolytic water hydrogen production storage tanks, lithium battery chemical raw material storage tanks, and pressure vessels for nuclear power auxiliary systems; radiation-resistant, corrosion-resistant, and with a high safety factor. 6. Special Industrial High-End Pressure Vessels: Aerospace testing pressure vessels, military pressure tanks, high-purity semiconductor process vacuum pressure vessels, suitable for stringent requirements such as high pressure, high purity, and non-magnetic operation.
