Baoji Dingding Titanium | Pressure resistant core of titanium alloy head forgings for pressure vessels and high-end equipment

Titanium alloy head forgings serve as the "terminal pressure barrier" for pressure vessels, storage tanks, and reaction vessels, directly determining the safe operation and service life of the equipment. Baoji Dingding Titanium Products Co., Ltd., relying on the forging process advantages of "China Titanium Valley", focuses on the research, development and production of titanium alloy heads of mainstream brands such as TC4, TA2, and Ti80. Full specification heads such as elliptical, dished, and spherical heads can be customized. Through the process of "integral forging+precision spinning", the wall thickness uniformity error of the head is ≤ 0.5mm, and the compressive strength is up to 150MPa, which is perfectly suitable for high-pressure and strong corrosion conditions in the fields of chemical industry, shipbuilding, aerospace, and so on.

1、 Core advantage: The irreplaceable value of titanium alloy heads

Compared to stainless steel and carbon steel heads, titanium alloy heads exhibit significant performance advantages under extreme working conditions and become the preferred pressure bearing components for high-end equipment

High voltage resistance performance

The tensile strength of TC4 titanium alloy head is ≥ 960MPa, and the overall forging has no weld defects. It can withstand high pressure impact of 100-150MPa, which is 40% higher than the pressure resistance limit of stainless steel head of the same specification, avoiding the risk of bulging and leakage under high pressure.

Global corrosion resistance characteristics

The surface dense oxide film can resist corrosive media such as hydrochloric acid, sulfuric acid, seawater, and aviation fuel. The corrosion rate after 5000 hours of salt spray testing is ≤ 0.0002mm/year, and the service life in highly corrosive chemical environments exceeds 20 years.

Lightweight and adaptable

The density is only 4.51g/cm ³, which is 55% lighter than carbon steel head and effectively reduces equipment load; It can seamlessly connect with titanium and steel containers, reducing the problem of corrosion in dissimilar material connections.

Precision molding quality

Using CNC spinning forming technology, the roundness error of the head is ≤ 0.1%, and the surface roughness Ra is ≤ 1.6 μ m. The sealing surface can be directly processed without additional grinding, shortening the customer's assembly cycle.

2、 Mainstream brand and customized specifications: covering all scenario requirements

Focusing on the core market demand, providing standardized and customized head solutions, suitable for all types of equipment from atmospheric storage tanks to high-pressure vessels:

Support customized heads with ultra large diameters (over 5000mm) and extra thick walls (over 60mm). Subsequent processes such as solution treatment, annealing, and surface acid washing can be carried out according to customer needs. The forging and delivery cycle is as low as 20 days.

3、 Core application area: Scene based implementation of head forgings

1. Aerospace field: "safety pressure barrier" for high-end equipment

Titanium alloy heads have become the core components of aerospace high-pressure vessels due to their lightweight design and high pressure resistance

-TC4 titanium alloy spherical head is used for aviation engine fuel tanks, which can withstand a working pressure of 120MPa and a high temperature of 400 ℃. It reduces weight by 30% compared to aluminum alloy head and improves the endurance of fighter jets;

-The Ti80 high-strength titanium alloy head is suitable for spacecraft propellant storage tanks, with no risk of brittle fracture in low temperature and vacuum environment of -180 ℃, ensuring the safety of propellant storage and transportation. It has passed aerospace grade reliability testing.

2. In the field of ship and ocean engineering: the "ocean weapon" for corrosion and pressure resistance

Faced with seawater corrosion and deep-sea pressure, titanium alloy heads have become the preferred choice for ships and marine equipment:

-TA2 pure titanium elliptical head is used for seawater cooling system storage tanks in ocean going ships. It can withstand 5000 hours of seawater immersion without corrosion, and its service life is 12 times longer than that of copper nickel alloy head, reducing ship maintenance costs;

-The TC4 thick walled head is used as the pressure resistant cabin end cover for deep-sea exploration robots, which can withstand a deep-sea pressure of 3000 meters (about 30MPa), while its lightweight characteristics enhance the underwater maneuverability of the robot.

3. Chemical and petroleum industries: the "core guarantee" for strong corrosion conditions

In the scenarios of strong corrosion in chemical industry and high pressure in petroleum, titanium alloy heads solve the problem of traditional heads being prone to corrosion and failure:

-TA2 titanium alloy head is used for hydrochloric acid and sulfuric acid storage tanks, which can resist the erosion of concentrated acid media and avoid safety accidents caused by leaks. It has been applied in raw material storage tank projects of multiple large chemical enterprises;

-The TC4 head is suitable for high-pressure reaction vessels in petroleum refining, and can work stably at a pressure of 150MPa and a high temperature of 350 ℃ without structural deformation, ensuring continuous operation of the refining process.

4. Medical devices and general industrial fields: precision adapted "multifunctional components"

-Medical equipment: TA2 pure titanium head is used for medical high-pressure sterilizers, with excellent biocompatibility and the ability to withstand repeated tests of high-temperature and high-pressure sterilization, ensuring the hygiene and safety of medical equipment;

-General Industry: TC4 head is used as a pressure tank for new energy battery packs, with lightweight characteristics that reduce the total weight of the battery pack, while also being resistant to electrolyte corrosion, improving the safety of the battery system.

4、 Quality assurance: Military grade forging and full process control

1. Strict control of raw materials: High purity sponge titanium with a purity of ≥ 99.8% is used, which is melted at least 3 times in a vacuum consumable arc furnace to ensure uniform composition of titanium ingots without segregation, and each batch of raw materials is traceable;

2. Forging process: The integrated process of "CNC fast forging+constant temperature spinning" is adopted, with a forging ratio of ≥ 5:1, eliminating defects such as internal looseness and porosity, and achieving a head density of ≥ 99.9%;

3. Full inspection: Each head undergoes ultrasonic testing (military grade I acceptance), hydraulic burst testing (1.5 times rated pressure without leakage), wall thickness and roundness testing, and additional low-temperature impact and fatigue testing for key aviation/military heads;

4. Surface treatment: Customized treatments such as acid pickling, passivation, sandblasting, polishing, etc. can be provided to meet the anti-corrosion and sealing needs of different scenarios.
