- Self introduction

- Required specifications

- Inquire about price/MOQ

Q:How much is the tube?
The first prerequisite we need to determine is: what are the specifications of the steel pipe mentioned? Such as the commonly used steel pipe specifications: diameter 108*4.5, diameter 219*6, diameter 377*10, diameter and wall thickness of steel pipe with different specifications, different weight, so the steel price per meter is different.
Q:What is the production process of seamless steel tube?
The main production process for hot rolling seamless steel tube (the main inspection):Tube preparation and check delta to billet heating, heating, rolling, perforated pipe, steel pipe and heat treatment, diameter (minus) Delta to finished tube straightening, finishing and inspection of delta (nondestructive, physicochemical, Taiwan inspection and warehousing)
Q:What does "buried steel pipe" 6*2SC100 mean?
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
Q:What's the difference between straight steel pipe and seamless steel pipe?
Observe whether there is weld seam. Welded pipe without treatment, there are obvious weld, there are bulges, like scars. A better point will shave off the weld, but there is a distinct difference between the eye and the eye. Also a small number of pipe will be processed after cold rolling, surface roughness and accuracy are relatively high, may be counterfeit seamless pipe sales. Careful observation will still show that the pipe wall will have a continuous spiral, metal luster slightly brighter, that is, the original welding seam, metallographic structure and other parts of the difference. To tell the truth, the layman would have to observe that it might be a little difficult.
Q:Fastener type steel pipe scaffold external parts name
Foot board can be made of steel, wood, bamboo and other materials, each quality should not be greater than 30kg. Stamping steel foot board is a kind of commonly used foot board, usually with thick 2mm steel plate pressing, length 2-4m, width 250mm, the surface should be anti-skid measures. Wooden feet can use the thickness of not less than 50mm fir wood or pine production, length 3~4m, width of 200-250mm, both ends should be galvanized steel band two, in order to prevent the wooden foot end of the destruction.
Q:How to make the magnetic steel, can be like a magnet?
Magnetization. Winding the insulated wire on the object, passing in the direct current, and taking it down after a period of time.
Q:What is lined pipe?
Pipe lining is a new technology in recent ten years of development, also called composite pipe conveying fluid with different needs, the use of different materials to make the durability of the pipeline inner wall and outer wall of pipeline, to ensure the purity of the fluid, pipeline adaptability, performance is greatly improved, more extensive use.
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
The difference is: 20# ordinary steel seamless steel pipe. 20G is the type of steel for high pressure boiler tubes.
Q:Are metal spiral tubes the same as metal bellows?
Hello. The two are not the same. The difference lies in. The pitch of a spiral pipe is much larger than that of a bellows. The maximum material thickness of the spiral tube is much thicker than that of the bellow. The diameter of a spiral tube can be very large. But the bellows can't be too big in diameter.
Q:Seamless steel pipe 8162 and 8163 what is the difference?
GB 8162 is the structure of the tube, there is no need for flaw detection, the use of mechanical processing, stents;
