Product Description:

Hot Rolled Stainless Steel Tube Used for Oil&Gas Trasportation Made in China


1.Structure of Stainless Steel Tube

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.


2.‍‍Main Features of the Stainless Steel Tube:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:What is the concept of stray fields in magnetic materials?
The stray magnetic field is related to the demagnetizing field of the magnet surface, which is mainly affected by the state of the surface of the magnet (edges, corners, defects, etc.), which originates from the magnetic dipole interaction between the free magnetic poles of the surface of the magnet.
Q:How do two powerful magnets pull together?
With this feature, a number of control components have been developed. For example, we use the rice cooker to take advantage of the Curie dot properties of magnetic materials. At the bottom of the rice cooker, a magnet is placed in the center and a magnetic material with a Curie point of 105 degrees. When the pot of water after the dry food, the temperature will rise from 100 degrees. When the temperature reaches about 105 degrees, due to magnetic material of the magnet magnet disappeared, it lost the suction, then the springs between the magnets and magnetic materials to separate them, and drive the power switch is disconnected, stop heating. Curie temperature is the temperature at which material can change between a ferromagnet and a magnet. Below the Curie temperature, the substance becomes ferromagnetic, when the magnetic field associated with the material is difficult to change.
Q:When the magnet reaches a certain temperature, the magnetism will disappear. How much temperature will the magnetism disappear?
When a general magnet reaches a certain temperature, the magnetism disappears, and at about 770 degrees, the temperature disappears.As for Tc, each magnetic material is different, for example, the Curie temperature of iron is about 770 DEG C, and the Curie temperature of cobalt is about 1131 DEG C.
Q:What are the stages of the development of rare earth permanent magnet materials?
The development of permanent magnet motor is closely related to the development of permanent magnetic material. China is the world's first found that the magnetic properties of permanent magnet materials and apply it to the practice of the country, two thousand years ago, China's use of the magnetic properties of permanent magnet materials made of the compass, played a huge role in navigation, military and other fields, has become one of the four great inventions of ancient china.
Q:What are the characteristics of ferromagnetic materials for transformers, cores, magnets, and permanent magnets?
Magnetic or not is the difference between the ferromagnetic and non ferromagnetic material, also is to see whether the material can be a magnet adsorption.
Q:SmCo and ferrite in magnetic energy on what is the difference? For brushless motor as specific as possible which good?!
Ferrite can not be done, it is applied in high frequency, such as switching power supply
Q:What is coercive force of magnetic material? What is its function? Is it larger or smaller?
Mean for magnetic materials plus how much force will make it less magnetic. Can not generally say good numerical or small, if you need to keep the material magnetic, apparently more good, if you need the material to have magnetic magnetic magnetic magnetic, do not have, obviously smaller.
Q:Is there a lot of dust in the magnetic material production workshop?
The current market is mainly NdFeB, ferrite, alnico and SmCo, magnetic FeCrCo, rubber and other materials
Q:What information can be obtained for ZC and ZFC of magnetic materials?
The ZFC/FC curve refers to the zero-field-cooling (zero field cold) and field-cooling (field cold) curves. Specifically, zero field cooling is in the absence of magnetic field cooling to a certain temperature, and then add the magnetic field, the temperature measurement of the temperature dependent magnetization curve; field cooling is in measuring the zero field cooling curve, then use the magnetic field while cooling while measuring the temperature dependent magnetization curve.In magnetic research, the ZFC and FC curves are very important and basic measurements to study the magnetic phase transition temperature and magnetic frustration.
Q:Mobile phone bracket magnetic effects on mobile phones?
Affect the magnet in the receiver so that you can't hear clearly,Some people say that the earth is a magnetic field, which is because the earth's magnetic field, magnetic force is too small, you use a 10 grams of NdFeB magnet to contact your mobile phone, your phone immediately scrapped
