How to reasonably design the structure of titanium elbow?

There is a new titanium alloy elbow with reasonable structural design, simple structure, not easy to corrode, good sound insulation, convenient dredging, and long service life. Its structure is reasonably designed as follows:

The titanium alloy elbow includes an elbow body. The two ends of the elbow body are respectively provided with port one and port two. The elbow body is composed of a titanium-based alloy layer, a sound insulation layer and an iron-based alloy layer from the inside to the outside. The titanium-based alloy layer The thickness of the alloy layer is 2.5mm, the thickness of the sound insulation layer is 3.5mm, the thickness of the iron-based alloy layer is 4mm, and the bending angle of the elbow body is 155-165 degrees. Among them, the bending angle of the titanium elbow body is 159°, which makes the fluid flow smoother and less likely to be blocked; the titanium-based alloy layer, sound insulation layer and iron-based alloy layer are combined to form an integrated structure.

In order to make the product more effective, a dredge is provided at the bend of the elbow body, and a sealing nut is threadedly connected to the outer end of the dredge. Port one and port two are both equipped with polytetrafluoroethylene sealing rings. The outer walls of port one and port two are made by welding connecting convex rings. Gr7 Ti-0.2Pd Titanium Foil / Titanium Elbow / Grade 12 Ti-0.3Mo-0.8Ni Titanium Plate

By adopting the above technical solution, the structural setting is reasonable, the titanium-based alloy layer has high strength, is not easy to deform, has good corrosion resistance, and has a long service life; the sound insulation layer makes the titanium elbow good insulating, and the fluid passing through the elbow has low noise; the elbow body The bending angle is set reasonably, the fluid flows smoothly and is not easy to block.

Titanium tubes are corrosion resistant and lightweight

Titanium tubes need to have sufficient strength and stiffness to meet the structural requirements of a specific application. Titanium alloys usually have high specific strength and specific stiffness, that is, high strength and stiffness per unit mass.

Titanium tube corrosion resistance: Titanium tubes should have good corrosion resistance and be able to resist corrosion and oxidation stably for a long time under various environmental conditions. The corrosion resistance of titanium alloys mainly comes from the dense oxide layer formed on its surface. Gr12 Ti-0.3Mo-0.8Ni Titanium Tube / Gr2 Pure Titanium Tube / Grade 9 Ti3Al2.5V Titanium Pipe

Titanium tube is lightweight: Titanium tube is lightweight and has good specific strength and specific stiffness, which can reduce the weight of the structure while maintaining sufficient strength and stiffness.

What are the product specifications and standards for titanium welded pipes?

Titanium welded pipe is a special metal welding material. Due to its excellent corrosion resistance and high-temperature strength, it is widely used in the chemical industry, medicine, shipbuilding, aerospace, and other fields. The product specifications and standards of titanium welded pipes mainly include the following aspects.

1. Product specifications

Outer diameter and wall thickness: The outer diameter and wall thickness of titanium welded pipes are its basic product specifications. According to different application requirements, titanium welded pipes of different specifications can be produced. The common outer diameter range is 0.5mm-200mm, and the wall thickness range is 0.1mm-10mm.

Length: The length of the titanium welded pipe can be customized according to customer needs. Common lengths are 6m, 12m, etc. At the same time, it can also be processed according to special needs, such as cutting into short sections, bending into arcs, etc.

Surface treatment: The surface of titanium welded pipes can be treated differently to meet different usage scenarios. Common surface treatments include polishing, sandblasting, pickling, etc.

Heat treatment: To improve the tensile strength and corrosion resistance of titanium welded pipes, heat treatment can be performed. Common heating treatment methods include solution treatment, aging treatment, etc.

2. Product standards

Global standards: The main global standards for titanium welded pipes include ASTM (American Society for Testing and Materials), ASME (American Society of Mechanical Engineers), ISO (Global Organization for Standardization), etc. ASTM B338 is a common global standard for titanium welded pipes, including requirements for titanium and titanium alloy seamless and welded pipes.

Domestic standards: Domestic standards for titanium welded pipes mainly include GB/T (national standards) and JB (aerospace industry standards). GB/T 3625 is China’s standard for titanium and titanium alloy seamless pipes, and GB/T 3624 is China’s standard for titanium and titanium alloy welded pipes. 3 Inch Titanium Pipe / Gr1 Pure Titanium Pipe / Grade 3 Pure Titanium Pipe

Corporate standards: Many titanium welded pipe manufacturers will develop their own corporate standards to meet specific customer needs or product characteristics. Enterprise standards usually refer to global standards or domestic standards, and make some supplements or improvements based on them with special requirements.

In addition to the above product specifications and standards, there are some other related specifications and standards that need attention.

Compliant pipe fittings: In the application of titanium welded pipes, some conforming pipe fittings are often needed, such as elbows, tees, reducers, etc. The specifications and standards of these pipe fittings need to match those of titanium welded pipes to ensure the reliability and sealing of their connections.

Testing standards: Quality testing of titanium welded pipes is an important step in ensuring product quality. Common testing standards include chemical composition analysis, mechanical property testing, non-destructive testing (ultrasonic, radiation, penetration, etc.), etc.

To sum up, the product specifications and standards of titanium welded pipes are relatively rich, mainly including specifications in terms of outer diameter, wall thickness, length, surface treatment, heat treatment, etc., as well as various standard requirements such as global standards, domestic standards, and corporate standards. These specifications and standards can ensure the product quality and performance of titanium welded pipes and meet the needs of different industries and fields.
