Seamless nickel titanium tube is a pipe made of nickel titanium alloy through seamless forming process, with the core feature of no welds and integral molding.

1、 Core Definition and Key Characteristics

Material basis: Shape memory alloy mainly composed of nickel and titanium, with a common ratio of about 55% nickel and 45% titanium.

Seamless core: formed directly through processes such as extrusion and drawing, with no spliced welds on the pipe wall, avoiding weak performance points at the welds.

Core performance: It combines shape memory effect (restoring the preset shape after heating), super elasticity (can undergo significant deformation and rebound under external force), corrosion resistance, and good biocompatibility.

2、 What is the difference between seamless nickel titanium pipes and seamless nickel titanium pipes?

This comparison angle is crucial, as the core difference lies in the performance differentiation brought about by structural integrity, and seamless nickel titanium pipes have more advantages in key performance.

Core performance differences

1. Structure and strength: Seamless pipes have no welds, and the overall mechanical properties are uniform, with higher tensile strength and yield strength; Welded pipes are joined by welding, and the weld seam is a weak point, which is prone to stress concentration and has lower strength and toughness than seamless pipes.

2. Corrosion resistance: Seamless pipe wall integration, no welding defects (such as pores and cracks), stronger corrosion resistance, especially suitable for medical and harsh working conditions; There may be residual impurities or micro cracks at the welded joints of welded pipes, which can easily lead to local corrosion.

3. Reliability and lifespan: Seamless pipes have no splicing hazards, are not easily broken or leaked during long-term use, and have higher stability; Welded pipes are prone to aging and failure at the weld joint under repeated deformation and pressure, resulting in a shorter service life.

4. Dimensional accuracy: Seamless pipes are formed through drawing and extrusion, with smooth inner walls, uniform wall thickness, and smaller dimensional tolerances; Welded pipes require subsequent processing, and there may be residual welding bars on the inner wall, resulting in slightly lower dimensional accuracy and surface smoothness.

Differences in applicable scenarios

Seamless pipe: Priority is given to performance demanding scenarios such as medical stents, aerospace components, high-pressure fluid delivery, etc.

Seam tube: suitable for ordinary scenarios with low requirements for strength and reliability, such as general industrial conduits, non core structural components, etc., and with relatively lower cost.

3、 Main application scenarios

Medical field: It is the core material for interventional medical equipment, used to manufacture stents, catheters, guide wires, etc. It can adapt to complex human cavities without damaging tissues.

Precision industry: used for elastic components and fluid transport pipelines in aerospace and electronic equipment, relying on its high reliability and environmental resistance.

Special scenarios: such as sensor housings and micro mechanical components, utilizing their integrated structure and excellent mechanical stability.
