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:How to make a great magnetic Sketchpad?
The magnetic drawing board of the prior art is composed of a bottom board, a magnetic writing board, a degaussing bar and a magnetic pen. The bottom plate is provided with a sliding groove and a guide rail; the magnetic writing board is an interlayer structure; the writing surface and the bottom surface are arranged; the writing surface is made of translucent plastic film; the interlayer is filled with colored magnetic material. When the magnetic pen in writing or drawing on the writing surface, non ferrous magnetic material in the interlayer, under the action of magnetic force with the trajectory of the tip of the writing surface adsorbed on the translucent, forming a visible text or picture. The erasing bar is arranged on the bottom surface of the writing board, and is provided with a bar shaped magnetic material, a slide block, a guide groove and a handle, wherein the strip magnetic material is clung to the bottom surface of the writing board.
Q:If a ferromagnetic material is inserted into the coil, what is the effect on the magnetic field of the coil?
The iron core after magnetization has also become a magnet, so that the magnetism of the solenoid is greatly enhanced because the two magnetic fields are superposed with each other. In order to make the electromagnet more magnetic, the iron core is usually made into hoofs.
Q:What is magnetic material?
A ferromagnetic material having a ferromagnetic order, and a broad range of weakly magnetic and antiferromagnetic materials that can be applied to its magnetic and magnetic effects.
Q:Is the paramagnetic transition of magnetic material reversible?
Theoretically, the transition from ferromagnetic to paramagnetic is a reversible process, and there is no doubt about it. After cooling down, it naturally turns from paramagnetic to ferromagnetic.
Q:Does the magnetic material belong to the aviation embargo or restricted cargo?
Whether the magnetic material should be transported by dangerous goods is determined by the magnetic strength of the outer packing of the goods.
Q:What are the uses of magnetic materials, please?
Magnetic materials have also been widely used in geological prospecting, marine exploration, as well as information, energy, biological and space technologies. Magnetic materials have a wide range of uses. Is mainly made of components or devices using its magnetic properties and special effects; for storage, transmission and conversion of electromagnetic energy and information, or have a certain strength and distribution of magnetic field in a certain space; sometimes the direct use of natural form materials (such as magnetic liquid). Magnetic materials play an important role in the field of electronic technology and other fields of science and technology.
Q:The exchange coupling effect in amorphous magnetic materials
Diamagnetic substance after magnetization also very weak intensity, magnetic field direction and magnetic field in the opposite direction, after the external magnetic field is removed almost completely disappeared.
Q:Barkhausen effect in different magnetic materials of different size why sound
The purpose of the experiment and the related experimental folding principle [Objective] by the Barkhausen effect of Barkhausen effect to verify the domain theory [] the experiment principle of ferromagnetic materials in the field of magnetization is essentially the domain are gradually changing, and the field domain to expand the domain of different to reduce gradually.
Q:Are magnetic materials used much in daily life?
The rotary magnetic material and high-frequency soft magnetic materials is ferrite material, because the metal will produce large eddy current effect in high frequency and microwave frequency, resulting in metal magnetic material can not be used, and the resistivity of ferrite is very high, will effectively overcome this problem, widely used. The magnetic material is morphologically. It includes powder material, liquid material, block material, film material and so on. Magnetic material is widely used in electroacoustic, telecommunication, electric meter, motor, memory element, microwave component and so on. Magnetic tapes for recording language, music, image information, magnetic storage devices for computers, vouchers for passenger travel, magnetic cards for fare settlement, etc.. Magnetic material is widely used in electroacoustic, telecommunication, electric meter, motor, memory element, microwave component and so on.
Q:What are the criteria for choosing magnetic materials for high frequency transformers?
First, consider energy transfer;The two is to consider the geometric size constraints;Three is to consider the magnetic core cross-sectional area and window area ratio, multi-channel output transformer generally requires a larger window area, choose EE, EI or PQ type magnetic core, can have larger windows and good heat dissipation.
