Titanium tube heat transfer efficiency to beat rivals titanium pump

From the viewpoint of heat transfer efficiency, we find that the titanium alloy pipes with other tubing

(e.g., copper-nickel alloy) match. sunrui aerospace investment castings High strength titanium and high impact resistance allowable turbidity of

seawater with high flow rates and titanium alloys have a high temperature corrosion resistance, titanium-

nickel alloy than copper heat exchanger 60 a weight reduction of 70%, the their overall heat transfer

efficiency is roughly the same.
     Due to the longer life of the sunrui titanium bicycle frame titanium tube structure to offset one-time investment, in terms of

economic efficiency is also something else. And because of the speed for the entire period in the life of

the tube can reduce downtime, thus also receive an additional character. With the growth and expansion of

the use of titanium production, the cost and availability of titanium improved. Titanium also with 317L

stainless steel, Monel alloy 400 and Sunrui Titanium Casting Golf Heads  Hastelloy C-276 to compete. It is predicted that in the middle with

seawater cooled heat exchangers, finned whole rolled titanium tube will completely replace copper-based

alloy tube.

Titanium tube material problems in the application Titanium alloy valve

If the main motivation for sunrui Titanium Welded Tube the use of titanium in some parts of the tube may be due to its high strength and low modulus of elasticity, so now to look at the use of the titanium tube Replacement parts are not effective or no benefit in several large cases .
     DelWest adoption in 1977 of the Ti-6A1-4v-made putter, although it weighs much lighter than steel valve set of parts, but it is located in the shorter side of the rocker arm, thus resulting benefits achieved very small signed into almost ineffective. Reciprocating engine parts to reduce weight for the practice is not always correct, but also Sunrui aerospace investment casting to be noted in particular used in conjunction with poor rigidity titanium tube part time. Manufacture of titanium tube past the crankshaft has not yet been widely used. Competition in some applications due to heavy internal crankshaft and the flywheel inertia, so they are expected to withstand the required engine speed. Titanium tube shield with torsional deformation increases may also cause insufficient lubrication, sunrui Titanium Golf Club Heads main bearing load is high and twisting significantly different frequencies.

From a historical perspective titanium widely adopted titanium sponge

Historically, the use of titanium for two main reasons: the structure of materials with properties; Sunrui Titanium Casting Manufacturer resistant to corrosion. Because titanium combination of high strength, low specific gravity, good toughness and has good resistance to smallpox labor performance, etc., so you can design excellent performance components. In many or most cases, the titanium can be obtained after annealing these properties, which greatly facilitates manufacturing. Chloride and titanium oxide dielectric, since the passivation layer is formed on the surface, thereby having a very good corrosion resistance, can be the same as the corrosion-resistant metal is set.
     The rise in the titanium sunrui titanium investment casting industry's first 20 years, titanium is mainly used in aviation and aerospace industry. Titanium production is unstable in 198t years ago, from about 1970, sales of titanium in the civilian industrial market began to rise, and relatively stable to 1981 civilian industrial markets titanium consumption of industrial production accounts for about 20 a 30%. Civilian industrial market volatility than small aviation and aerospace industry, which for the stable development of the industry in Chin provided favorable Sunrui titanium ingot price conditions.

According to the information in September

According to the information in September 1981 statistics, there WAO wastewater treatment unit 13 of the city is made ​​of titanium tubing. Except one, the other is under pressure temperature 175-204 ℃ Titanium Casting Manufacturer and 2.4-3.4MPa be thermal regulation. Rensselaer, NY thermal conditioning apparatus at 204 ℃, the degree of oxidation of 50% water. In the United States the longest running titanium tube device is in the state of titanium casting factory Florida boiling Lauderdale, this device has been in operation since 1972. Capacity and enable all of these dates titanium sewage sewer pipe manufacturing unit. 

     In these devices, the chloride ion concentration is 500 to water 2500ppm, pH value of 4.3-5.0. So far, none of titanium companies these devices are all aspects of the corrosion problems occurred

Beneficial properties and research in the field of titanium tubes titanium alloy pump

Because titanium tube in aviation, aerospace application of achievements, but also attracted dedicated and Sunrui Titanium heat exchangers imaginative world's scientists and engineers handsome, prompting them through discussions and meetings, such as symposia, technical exchange meetings, international conferences etc. to exchange Aerospace titanium castings information and to develop further plans. Undoubtedly, the nature of its research titanium tube new application areas is certainly beneficial.
     It is clear that the titanium tubes in the energy and industrial applications thanks to the aviation, aerospace industry has been achieved. So, in the future they are also in Sunrui titanium material those areas can support each other it? Conversion or exchange of information which can be considered from two aspects of the future development of the titanium tube industry and technology.

The titanium material using a mold of a rigid

 Cutting - like a ttitanium valve punch in the desired shape punched out the hair department. Concentric shape of titanium, the maximum cutting thickness of 3.2 mm, the maximum thickness of the irregular shape of the wool is 1.3 mm. 1.3 mm thick titanium plate below, filling the mold with the soil to create a tolerance of 0.1 mm; But for titanium wins 3.2 meters below, shall tolerances down to ± 0.025 mm. Warming will reduce the thickness of titanium cutting edge cracks.
     Die should titanium plate aerospace investment castings having rigidity, the upper and lower guide post to maintain the exact relative positions of the mold. When the material thickness increase, such a requirement is more urgent. Less rigid process equipment will cause mold damage and cattle production sheet metal edge crack. Die cutting edge should be sharp, no uneven. Gap material mode of titanium, can be expected under aircaft investment ordinary copper mold with a gap, but the shear angle should be larger.

Comparative analysis of thin titanium plates spinning and spin Sunrui titanium pump

 Titanium plates spinning at the beginning of the tenth century from China, passed the fourteenth century

Europe. At this stage only a Titanium Welded Tube small initial shaping with titanium and titanium alloy. Space program raised

the need for a fuel tank large head, which makes the spinning process once again being taken seriously.

Spinning and spin thin enough rotational force and pressure by the combined effect of titanium plate and

forming a part of the process. titanium tube Rotary thin material thickness caused thinning; while spinning, the material

thickness changes little.
    Due to the larger spin-thin power equipment, so thick and thin titanium thin titanium plate can be

screwed; But spinning is Titanium casting limited to a thin titanium parts.

Embedding material impact on the physical Sunrui titanium check valve

Embedding material impact on the physical and chemical properties of titanium tube casting quality
    Embedding material as titanium titanium casting tube casting modeling materials, has been cast alloy tube technology

research an important topic. As we all know, the chemical nature of the high temperature titanium incredibly

lively, very easily oxidized, easy embedding material response.
    Titanium pipe foundry Titanium castings casting process is often incomplete and internal porosity phenomenon, mainly due

to addition of titanium alloy tubes at high temperature nitrogen, hydrogen, oxygen has a strong affinity and

embedding material response, titanium casting process the embedding material titanium tube permeability also an important factor

affecting the quality of castings.

Metal casting surface deformation, flow marks defects titanium heat pumps

 Deformation, surface flow marks were casting and casting design related. Casting too small, except

Casting incomplete, Titanium Welded Tubes the surface of the casting marks often exist, casting deformation obvious. Furthermore,

the quench casting defects will result in the above.
     As a new titanium dental materials with excellent biocompatibility, high strength, good corrosion

resistance, semi-transmissive titanium investment castings advantages for X-ray showed, is an ideal repair material. However, titanium

casting technology in only 10 years of history of dental prosthesis production, production of cast titanium

denture and partial denture fixed frame is still in the development stage. Need to constantly sum up

experience in the dental cast Titanium casting titanium, improving the quality of titanium denture.
