Pressure bearing core of Baoji Dingding titanium | titanium and titanium alloy forging cylinder under extreme working conditions

As the "core pressure carrier" of pressure vessels, power systems, and transmission pipelines, titanium and titanium alloy forged cylinders' wall thickness uniformity, density, and corrosion resistance directly determine the upper limit of safe operation of equipment. Baoji Dingding titanium products Co., Ltd. relies on the advantages of the whole industrial chain of "China Titanium Valley", focusing on the R&D and production of TC4, TA2, TC11 and other mainstream brands of forging barrels. Through the integrated process of "overall forging+CNC finishing", the inner diameter tolerance of the forging barrel is ≤± 0.5mm, and the compressive strength is up to 200MPa, which is perfectly suitable for high-pressure and strong corrosion conditions in aerospace, petrochemical, naval and military industries.

1、 Core advantage: performance barrier of titanium and titanium alloy forging barrel

Compared with stainless steel and carbon steel forging cylinders, titanium and titanium alloy forging cylinders show irreplaceable comprehensive advantages in extreme environments, and solve the industry pain points of traditional cylinder parts such as "corrosion failure, heavy weight and insufficient pressure resistance":

High pressure bearing capacity

The tensile strength of TC11 titanium alloy forging cylinder is ≥ 1000MPa, the overall forging is free of weld defects, and the forging ratio is ≥ 6:1 to ensure that the internal structure is compact, and can withstand 150-200mpa high pressure, which is 50% higher than the pressure limit of stainless steel cylinder of the same specification, avoiding the risk of bulge and leakage under high pressure.

Global corrosion resistance

The dense oxide film on the surface can resist strong corrosive media such as hydrochloric acid, sulfuric acid, sea water and aviation fuel. The corrosion rate of 5000 hours salt spray test is ≤ 0.0002mm/year, and the service life of the cylinder in the chemical strong corrosive environment is more than 12 times longer than that of the traditional cylinder.

Significant lightweight advantages

The density is only 4.51g/cm ³, which reduces the weight by 45%-55% compared with the steel forged cylinder of the same specification, effectively reducing the overall load of the equipment, and directly improving the endurance and maneuverability of the equipment in aerospace, ships and other weight sensitive fields.

Stability in wide temperature range

It has stable performance in a wide temperature range from -200 ℃ (deep space environment) to 500 ℃ (high temperature working condition), without low-temperature embrittlement and high-temperature creep, and is suitable for complex temperature scenarios from polar scientific research to aeroengines.

2、 Core brand and customized specification: covering the requirements of the whole scene

According to the performance requirements in different fields, it provides standardized and customized forging cylinder solutions to meet the full specification requirements from micro precision cylinder parts to large pressure vessels:

It supports the customization of ultra large specification (inner diameter above φ 1200mm), variable diameter and flange integrated forging cylinder. The follow-up processes such as solid solution aging, annealing and surface pickling can be carried out according to customer requirements. The whole process delivery cycle from forging blank to finished product is as low as 30 days, and the green production channel is opened for military emergency orders.

3、 Core application field: scenario landing of forging cylinder

1. Aerospace: the "power pressure core" of high-end equipment

Titanium and titanium alloy forged cylinder is the key carrier of aerospace power system and structural parts, bearing the test of extreme conditions:

-TC11 forged barrel is used in aero-engine combustion chamber. It has excellent creep resistance at 500 ℃ and 180MPa pressure. Compared with superalloy barrel, it reduces weight by 40% and directly improves the thrust weight ratio of engine;

-TC4 forged cylinder is suitable for spacecraft propellant storage tank. There is no risk of embrittlement under -180 ℃ low temperature and vacuum environment. The density ≥ 99.95% ensures that the propellant has no leakage. It has passed the aerospace level reliability test.

2. petrochemical industry: "safety barrier" with strong corrosion and high pressure

In highly corrosive and high-pressure scenarios such as petroleum refining and chemical reactions, titanium and titanium alloy forged cylinders solve the problem that traditional cylinders are prone to failure:

-TA2 pure titanium forged cylinder is used for hydrochloric acid and sulfuric acid storage tanks, which can resist the erosion of concentrated acid medium. Its service life is more than 20 years, and the maintenance cost is reduced by 90% compared with stainless steel storage tanks. It has been applied in many large chemical enterprises;

-TC4 forged barrel is suitable for oil high-pressure drilling pipeline. It can work stably under 150MPa pressure and corrosion of sour crude oil without structural deformation and avoid blowout risk during drilling.

3. ship and marine engineering: a "corrosion-resistant weapon" for the marine environment

In the face of seawater corrosion and deep-sea pressure, titanium and titanium alloy forged cylinders show excellent adaptability:

-TA2 pure titanium forged cylinder is used in the seawater cooling system of ocean going ships. It has no corrosion after 5000 hours of seawater immersion, and its service life is 10 times longer than that of copper alloy cylinder, reducing the frequency of ship maintenance;

-TC4 thick wall forged cylinder is used as the pressure cabin of the deep-sea exploration robot, which can withstand 3000 meters of deep-sea pressure (about 30MPa). At the same time, the lightweight characteristics improve the underwater mobility of the robot.

4. military industry and general industry: a "multi-functional carrier" for precise adaptation

-Military industry: TC11 forged barrel is used for the shell of missile warhead. Its high strength and density ensure the accurate release of explosion energy without the risk of shell rupture;

-General industry: TA2 pure titanium forged cylinder is used for pressure tank of new energy battery pack, which is resistant to electrolyte corrosion and lightweight, and improves the safety and endurance of battery system.

4、 Quality assurance: military industry level whole process control system

1. raw material traceability control: adopt ≥ 99.8% high-purity sponge titanium, which has been melted in vacuum consumable arc furnace for ≥ 3 times. Each batch of raw materials is attached with a composition analysis report to ensure that the composition of titanium ingot is uniform without segregation and can be traced throughout the process;

2. precision forging process: the integrated process of "numerical control fast forging+constant temperature precision forging" is adopted, and a 2000 ton multi-directional fast forging machine is equipped. The temperature and pressure are monitored in real time during the forging process to ensure that the wall thickness of the forging cylinder is uniform and free of internal defects;

3. full inspection and verification: all products have passed ultrasonic flaw detection (military grade I acceptance), hydraulic explosion test (no leakage at 1.5 times the rated pressure), mechanical property test and corrosion resistance verification, and aviation/military products have been additionally tested for high and low temperature fatigue and creep;

4. customized surface treatment: it can provide customized surface treatment such as pickling passivation, sandblasting, polishing, coating strengthening, etc., to improve corrosion resistance and surface hardness, and meet the needs of different scenarios.
