The raw material of carbon steel tube is round tube billet, round tube embryo to be cut by cutting machine processing billet with growth of about 1 meter, and sent to the furnace by conveyor belt heating. The billet is fed into a furnace and heated to about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is the key problem. After the round tube billet comes out, it is perforated by the pressure punch. Generally, the most common perforator is the conical roll perforator.

After the round tube billet comes out, it is perforated by the pressure punch. Generally, the most common perforator is the conical roll perforator. This kind of perforator has high production efficiency, good product quality, large perforating diameter and can wear a variety of steel. After perforation, the round tube billet is successively rolled by three high diagonal, continuous rolling or extrusion. After extrusion, the pipe should be removed for sizing. The caliper rotates into the steel embryo through a conical drill at high speed to punch holes and form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the caliper drill bit. After sizing the steel pipe, it enters the cooling tower and is cooled by spraying water. After cooling the steel pipe, it will be straightened. After straightening, the steel pipe is sent by conveyor belt to the metal inspection machine (or hydraulic test) for internal inspection. If there are cracks, bubbles and other problems inside the steel pipe, it will be detected. Steel pipe quality inspection after the strict hand selection. After the steel pipe is inspected, the number, specification and production lot number are sprayed with paint. And by the crane into the warehouse.

Stainless steel plate is generally stainless steel plate and acid-resistant steel plate. Coming out at the beginning of this century, the development of stainless steel plate for the development of modern industry and scientific and technological progress has laid an important material and technological foundation. There are many kinds of stainless steel plate, different performance, it has gradually formed several categories in the process of development.

Properties of stainless steel plate
The stainless steel plate has similar resistance to general corrosion as the unstable nichcr 304. Prolonged heating in the chrome-carbide degree temperature range may affect alloys 321 and 347 in harsh corrosive media. It is mainly used in high temperature applications, where the material is required to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.

Application prospect of stainless steel pipe
Stainless steel pipe is a kind of economic cross-section steel, is an important product in the steel industry, can be widely used in life decoration and industry, many people in the market for making stair handrails, window protection, railings, furniture and so on. There are two common materials, 201 and 304.

Cause of 304 steel rust phenomenon
Chloride ions are found in many places, such as salt, sweat, sea water, sea wind, soil, and so on. In the presence of chloride ions, stainless steel corrodes quickly, even more than ordinary mild steel. Chloride ions form a complex with Fe in the alloying element, which reduces the positive potential of Fe, and then is oxidized by oxidizing agents who take away electrons [1]. So there are requirements for the use of stainless steel environment, and the need to wipe often, remove dust, keep clean and dry.
