Product Introduction

Introduction to nickel titanium alloy tube

Nitinol tube is a round product produced from nickel titanium alloy. Nitinol tube is an alloy material with shape memory and super flexibility. Has a smooth appearance, high surface finish and darker color. When processing nickel-titanium composite pipes, cold drawing or hot drawing processes are usually used, which not only ensures the perfection and surface properties of the nickel-titanium alloy pipes, but also can handle complex shapes. Nickel-titanium tubes have superelasticity and shape memory properties, can quickly reconstruct their unique shapes in a short time, and have strong deformation capabilities to adapt to different complex planning needs.

application:

Nitinol tubes exhibit shape memory and superelastic properties during processing.
Biocompatible and non-toxic: making it ideal for use in a range of medical devices, including in vascular stents, heart bypasses, surgical instruments, endoscopes and guidewires. Shape memory and superelastic properties: It can return to its original shape after deformation and can be used for some minimally invasive surgeries. The high degree of bending and twisting will not damage the structural integrity or cause damage to the tissue. Therefore, it is particularly useful in minimally invasive surgery. In addition, the tube is highly corrosion-resistant and can easily handle the sterilization process. In cardiology, nickel-titanium tubes are commonly used in coronary stents to restore blood flow to blocked arteries. Urologists use nickel-titanium tubes during endoscopy to remove bladder and kidney stones. Neurologists also use the tube to perform minimally invasive surgeries to remove brain tumors.

Packaging and shipping

I pay great attention to the packaging of the product and avoid damage during transportation of the product.
First of all, there should be no looseness in the packaging room to avoid collision during transportation and damage caused by external impact.
Secondly, depending on the quantity, for a small amount of nickel pipes, we will put a plastic protective cover on each pipe. If the quantity is large, we will put a plastic protective film on the target bundle, and use sponge pads to separate the pipes from the wooden boxes. Open to prevent the possibility of the wooden box scratching the pipe during transportation. Thereby increasing the safety of cold pipes.
