Dingding Titanium Industry: Corrosion resistant titanium alloy solutions in the field of chemical equipment

In the chemical production environment, strong acids, strong alkalis, high temperature and high pressure, and multiphase corrosive media pose severe challenges to equipment materials. Material failure not only leads to production line shutdown, but also may cause safety accidents. Baoding Dingding Titanium Products Co., Ltd. relies on the industry accumulation and perfect quality system of "China Titanium City" to customize titanium alloy rods, plates, wires and other products for chemical equipment needs. They are widely used in core equipment such as reaction vessels, heat exchangers, and conveying pipelines, and have become the preferred partner for chemical enterprises to improve equipment reliability.

1、 Focusing on three core chemical scenarios, accurately solving corrosion pain points

Going deep into the front line of chemical production, customized titanium alloy solutions with "corrosion resistance, high temperature resistance, and easy processing" are tailored to the medium characteristics and working conditions of different process links, accurately matching equipment performance requirements.

1. Titanium alloy for corrosive reaction equipment: resistant to strong acid and alkali corrosion

The reaction vessels, stirring blades, and heads in industries such as fertilizers, pharmaceuticals, and dyes are exposed to strong corrosive media such as sulfuric acid, hydrochloric acid, and nitric acid for a long time, facing two core pain points of "local corrosion perforation and uniform corrosion thinning". The service life of traditional stainless steel equipment is often less than one year. Dingding Titanium Industry provides exclusive solutions based on corrosion-resistant titanium alloys such as TA9, TA10, Ti-0.2Pd, etc

The TA10 titanium alloy plate produced by the "high-purity sponge titanium+vacuum melting" process has a corrosion rate as low as 0.003mm/year in concentrated sulfuric acid at 70 ℃, which is 1/100 of 316L stainless steel. It can achieve stable operation of the reaction kettle for more than 5 years, greatly reducing equipment replacement frequency and maintenance costs. A customized Ti-0.2Pd titanium alloy rod was developed to address the stress corrosion problem in chloride media. By adding palladium element to optimize the composition, there is no risk of stress corrosion cracking in chloride containing solutions. The tensile strength reaches 650MPa and the yield strength is ≥ 480MPa, meeting the pressure requirements of the reaction vessel.

We can customize titanium alloy plates with a thickness of 2-50mm and titanium alloy rods for stirring shafts with a diameter of 10-200mm according to the volume and pressure level of the reaction vessel. The dimensional tolerance is controlled within ± 0.03mm, and it supports complex forming processes such as rolling and stamping. It has been applied in large-scale fertilizer plants for synthetic ammonia reaction vessels and pharmaceutical companies for acid-base neutralization vessels.

2. Titanium alloy for heat exchange and condensation equipment: balancing efficient heat transfer and corrosion resistance

Heat exchangers, condensers, and evaporators in the fields of petrochemicals and fine chemicals work in environments with high temperatures (100-300 ℃), high pressures, and two-phase corrosion of steam and liquid, which can easily lead to problems such as corrosion and leakage of heat exchange tubes, scaling affecting heat transfer efficiency, directly resulting in a decrease in heat transfer efficiency and cross contamination of the medium. Dingding Titanium Industry's targeted research and development of titanium alloy products such as TA9, TA10, TA2, accurately solves pain points:

Through the optimization of the "precision rolling+bright annealing" process, the surface roughness of titanium alloy heat exchange tubes is controlled below Ra0.6 μ m, and the heat transfer coefficient is increased by 12% compared to ordinary titanium tubes, while reducing the adhesion of medium scaling. The TA2 titanium alloy tube produced has a corrosion rate of less than 0.005mm/year in a mixed medium of saturated steam and hydrochloric acid at 200 ℃, and its service life is 6-8 times longer than that of stainless steel heat exchange tubes. In response to the demand for high-pressure heat exchangers, the customized TA18 titanium alloy tube has a compressive strength of 40MPa, which can adapt to the harsh working conditions of high-pressure hydrogenation units.

We provide titanium alloy heat exchange tubes with an outer diameter of 10-50mm and a wall thickness of 0.5-5mm, supporting various connection methods such as expansion and welding. We have provided heat exchange tubes that comply with the GB/T 3625-2007 standard for multiple refineries, helping to improve their heat exchange efficiency and extend equipment life.

3. Titanium alloy for conveying and storage equipment: suitable for multi-media conveying needs

Chemical raw material transportation pipelines, storage tanks, valves and other equipment need to be adapted to the working conditions of "multi-component corrosive media, frequent start stop impact", which requires materials to have broad-spectrum corrosion resistance and meet the reliability of pipeline welding and valve sealing performance. This is the core concern of chemical enterprises. Dingding Titanium Industry's solution is as follows:

Customized TA2 pure titanium sheet exhibits excellent corrosion resistance to various media such as organic acids, alkaline solutions, and salt solutions. It can be used for storage tanks to achieve "mixed storage of acidic and alkaline raw materials" without corrosion risks. Its specific strength is 1.5 times that of carbon steel, which can reduce the weight of storage tanks by 30% and reduce infrastructure construction costs. The titanium alloy wire developed for pipeline transportation has a welding seam strength of over 96% of the base material, and the corrosion rate of the weld seam is consistent with that of the base material. There are no weak welding links, which can avoid safety hazards caused by medium leakage.

The titanium alloy valve core for valves adopts the process of "integral forging+precision grinding", with a surface hardness of HV280 and excellent wear resistance. The leakage rate of the sealing surface is less than 1 × 10 ^ -6 Pa · m ³/s, which meets the strict sealing standards of chemical pipelines. It has been applied to the multi-media transportation pipeline network in chemical industrial parks.
