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:Better magnetic material for help
Permeability is defined as the slope of the magnetization curve, the ease of simple speaking is magnetic magnetization, and coercive force is just opposite.
Q:Are galvanized steel pipes and stainless steel tubes non-magnetic?
304. and 316 of the material will not be magnetic, but after processing with a small amount of mechanical magnetism.
Q:Can magnetic energy be transmitted?
A magnetic object will magnetize a magnetic material close to it into a magnet, and a new magnet will magnetize the magnetic material close to it...... In theory, there is no end to it. But the weaker the magnetism, the less likely it is to ignore the magnetic transmission you ask
Q:After the magnet attracts the mold, how to go to the magnetic?
The Curie temperature is not magnetic at all temperatures for all magnetic materials. Generally, a magnetic material has a critical temperature Tc, at which the arrangement of atomic magnetic moments is disordered due to the intense thermal motion of atoms at high temperatures. Below this temperature, the magnetic moment of the atom is arranged in order, producing spontaneous magnetization, and the object becomes ferromagnetic. With this feature, a number of control components have been developed.
Q:Why strong magnet in iron, over a period of time after the block has a certain magnetism?
This is the phenomenon of magnetization. Magnetization is the process of ordering magnetic material which is not magnetic. Magnetic materials are divided into many tiny regions, each of which is called a magnetic domain, each of which has its own magnetic distance (i.e., a tiny magnetic field).
Q:What are ferromagnetic materials?
Metal magnetic material refers to magnetic materials made of metal alloys or compounds, mostly in iron, nickel or cobalt based, then add other elements by high temperature melting, heat treatment and mechanical processing is made, the magnetic materials in high temperature, low frequency and high power conditions, has been widely used, but in high frequency the scope of its application is restricted. Metal magnetic materials can be divided into hard and soft magnetic and magnetoelastic materials, experimental results show that the hysteresis loops of different ferromagnetic materials have great differences, this gives three different ferromagnetic material hysteresis loop, the minimum area of soft magnetic material; magnetic material the high coercivity, remanence while large; loop ferrite material is approximately rectangular, it also known as the moment of magnetic materials.
Q:What is the basis for a substance to be magnetized?
Magnetic materials are divided into many tiny regions, each of which is called a magnetic domain, each of which has its own magnetic distance (i.e., a tiny magnetic field). Generally, the magnetic distances of each domain are different, and the magnetic fields cancel each other, so the whole material is not magnetic. When the direction of each domain is uniform, the whole material shows magnetism.The so-called magnetization is to make the magnetic domain of the magnetic domain in the magnetic material become consistent. When the material that does not exhibit magnetism is placed into another strong magnetic field, it is magnetized, but not all materials can be magnetized, and only a few metals and metal compounds can be magnetized.
Q:What is the magnetism of the material?
Magnetic material is an old and widely used functional material, and the magnetism of material has been recognized and applied as early as 3000 years ago. For example, in ancient China, natural magnets were used as the compass. Modern magnetic materials have been widely used in our daily life, such as the permanent magnetic material is used as the core material used in motor, transformer, magnetic disc memory used as magnetic recording by computer, such as floppy disks. It can be said that magnetic materials are closely related to information, automation, mechatronics, national defense and the national economy. It is generally believed that a magnetic material is a substance that produces magnetism directly or indirectly by excessive elements such as iron, cobalt, nickel, and their alloys.
Q:Who has NdFeB, the performance parameters of various magnetic materials and the content of various components?
NdFeB based on iNd2Fe14B, the actual composition is Nd15Fe77B8, containing rich Nd consistent rich B phase (BH), =407, Hc=2244, Br=1.48
Q:Is silicon steel sheet a magnetic material?
Silicon steel is a silicon iron alloy with silicon content of about 3%. Silicon steel sheets are widely used in medium and low frequency transformers and motor cores. Silicon steel is characterized by its highest saturation magnetic flux density (2.0T or more) in common soft magnetic material, so it can work at very high working points as a transformer core (for example, working magnetic induction 1.5T). However, silicon steel in soft magnetic materials commonly used in iron loss is the largest, in order to prevent the core caused loss is too large, its use frequency is not high, the general can only work under 20KHz, mainly used in power transformer.
