Read titanium forgings, Flange/pipe/fitting/hook/bearing selection process and pit avoidance solution in chlor-alkali, Marine Engineering, Chemical corrosion conditions, Many equipment failure problems stem from deviations in material selection details, Taking Wet Chlorine Preheater as an Example, Drawing designation TA10 Titanium forging flange, If plate welding flange is misused, Under 80℃ humid chlorine environment, Corrosion and leakage of welds can occur in just a few years, The integral titanium forging flange can run stably for more than ten years.Titanium forgings rely on dense forging structure, comprehensive strength is better than the same brand
Titanium PlateMaterial, is the key to the high pressure bearing, core bearing equipment accessories.In this paper, combined with industry practical experience, Five types of titanium forgings, Forging Technology, Price Difference of Domestic Import and Main Points of Avoiding Pit in Procurement, Suitable for industrial project selection reference, can be matchedindustrial engineering
Titanium Plate、titanium pipeproductComplete selection and matching.
Core Selection Conclusion, Titanium forging is not a simple titanium forging process, After forging process optimization, The material structure is denser, Mechanical properties compared to ordinary
Titanium Platewood significantly improved, It's a high-pressure condition, core bearing capacity, Preferred accessories for sealing connection equipment, Bearing equipment pressure, bearing, connect, Seal four core functions.
First, five mainstream titanium forging categories and application scenarios
Industrial titanium forgings are divided into five categories to meet the needs of different equipment conditions.Titanium flangeForgings are mostly used in pressure vessels and pipeline high-pressure connection scenarios, and conventional specifications cover DN15 to DN600;Titanium nozzle forgings adapt to container nozzles and equipment reinforcement structures, with specifications ranging from DN50 to DN800;titanium pipeForgings include elbow, tee, size and other special fittings, suitable for pipe diameter, steering, diversion conditions;Titanium hook rings are mainly used for marine equipment, lifting equipment bearing structure, can adapt to 1 to 50 tons of bearing requirements;Titanium bearings and shaft forgings are mostly used for corrosion resistant transmission equipment, Machining diameter range 30mm to 500mm, Adapt to all kinds of precision transmission conditions.Different types of forgings can be matched with forging process according to needs, adapting to various working conditions from low pressure to high pressure, conventional corrosion to strong corrosion.
Second and third types of forging process differentiation adaptation rules
At present, the mainstream forging process in the industry is divided into free forging, die forging, Precision special forging three, Adapt to different production lot sizes and precision requirements.Free forging is suitable for medium and large forgings, single piece and small batch production, and the process is universal. The market price is the industry benchmark price.Die forging rely on special die processing, high precision of product size, good consistency, Mostly used for medium and small batch forging, The price is 20% to 30% higher than that of free forgingPrecision special forging includes precision forging, rotary swaging technological, high precision, stable mechanical properties, Adapt to high-end bearing capacity, Precision equipment accessories, Price rises higher than benchmark process, adaptive aviation, Nuclear power and other high-end operating conditions.
III. Matching scheme for working conditions of mainstream material grades
Different titanium forgings have significant differences in fitting conditions, and reasonable selection can greatly prolong the service life of equipment.TA2 and TA10 materials are preferred for flanges and connecting pipe forgings under normal pressure and strong corrosion conditions;Flange fittings under high temperature, high pressure and high strength conditions, suitable for TC4 titanium alloy forgings;TA2, TA10 and TA9 materials can be selected for pipe forgings in strong corrosive medium environment;Marine equipment and lifting hooks shall be made of TA2 or TC4 material with both bearing capacity and corrosion resistance;Corrosion-resistant drive bearings, transmission shaft, High-strength TC4 forgings are preferred, High temperature adaptation, corrosion, High pressure compound working condition.
IV. Reference of practical engineering cases
The practical value of titanium forgings is proved by several industrial enterprise transformation cases.Modification of wet chlorine preheater in large caustic soda plant, Replacement of corrosion-prone TA10 plate weld flanges with integral free-forging flanges, Adapt to 80℃ wet chlorine working condition, Equipment operation stability greatly improvedOffshore wind power project replaces traditional stainless steel hooks with TA2 forged hooks, Effective resistance to chloride ion corrosion in marine atmosphere, significantly greater lifePTA chemical plant will replace stainless steel bearings with TC4 precision forging bearings, Suitable for high temperature acetic acid corrosion conditions containing bromine, Completely solve the problem of pitting failure of components, Significantly reduce equipment operation and maintenance costs.
Five, titanium forgings standardized production process and core parameters
Regular titanium forgings production process rigorous, Retesting from raw materials, high temperature forging, vacuum annealing, precision machining, Pickling passivation detected NDT, Finished product inspection is controlled layer by layer.Forging temperature strictly controlled at 850-950℃, Avoid grain coarsening caused by high temperature oxidation, Forging ratio not less than 4, fully crus as-cast structureAdopt vacuum or argon protection annealing process to eliminate machining stress;100% ultrasonic nondestructive testing of finished products, Penetration testing added to critical accessories, Hardness of sealing surface not less than 180HV, Ensure stable sealing performance, All processes comply with national and American standards.
VI. Price comparison between domestic and imported titanium forgings in 2026
At present, the domestic titanium forging process is mature, the performance can be compared with the standard imported products, and the cost performance advantage is outstanding.Regular TA2, TC4 industrial forging, Domestic prices are only about 50% of imported products, The domestic price of aviation grade precision titanium forgings also has obvious advantages compared with imports.where conventional flanges, take over, Large quantities of shaft forgings can enjoy ladder discounts, Unit price can be reduced by 10% to 15%, It can completely replace imported products and adapt to most industrial conditions., Ultra-high precision aviation only, Imported materials can be selected as required for nuclear power first-class components.
Seven, procurement processing five pit avoidance points and industry FAQ
Titanium forging procurement to avoid five common problems, Eliminate plate welding instead of forging, Forging temperature exceeded, Insufficient hardness of sealing surface, Omit NDT, Mechanical properties are not up to standard and other problems, Avoid hidden dangers of equipment operation from the source.Procurement verification needs to focus on verification of material furnace batch report, NDT data, sealing surface hardness, mechanical property parameters, Five core indexes of forging process standard.At the same time, the selection scenarios are distinguished. Integral forgings are required for high pressure corrosion conditions, and plate weldments are available for low pressure conventional conditions.Free forging and die forging process can be selected according to requirements, giving consideration to cost and service performance.
