Hot rolled stainless steel tubes are generally produced on automatic tube rolling mills. After inspection and removal of surface defects, centered on the end face of the perforated end of the pipe blank, and then sent to the heating furnace for heating and perforated on the piercer. During perforation, it rotates and advances continuously. Under the action of roll and plug, a cavity is gradually formed inside the pipe blank, which is called rough pipe. Then it is sent to the automatic pipe mill to continue rolling. After that, the wall thickness of the whole machine is adjusted, and the diameter is determined by the sizing machine to meet the specification requirements. It is advanced to produce hot rolled seamless steel pipe by continuous pipe mill.

In view of the continuous vibration of stainless steel pipe shopping malls even & ldquo; Roller coaster & rdquo; Market, the national stainless steel pipeline inventory has been at a low level. High price various specifications of stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. Waste merchants, industrial companies, enterprises and power departments are welcome to visit and negotiate with the company! At the beginning, the social inventory of stainless steel pipes should progress with the progress of economic aggregate, and with the progress of total output and demand. However, stainless steel pipe inventory did not increase too much, or even did not increase,1 cm thick stainless steel plate, indicating a relative decline in social inventory level. Low inventory has indeed played a role in market stability.

.Model 416 & mdash; The addition of sulfur improves the processability of the material.

The folded stainless steel hot rolled strip is hot rolled into a strip with a thickness of 80mm-00mm and a width of 50mm-1200mm.

.  ·Sewage treatment system.

The cold working process performance and cold forming performance are much better than that of ferritic stainless steel.

Cold drawn (rolled) seamless steel pipe: round billet → Heating → Perforation & rarr; Lead & rarr; Annealing & rarr; Pickling → Oiling (copper plating) → Multi pass cold drawing (cold rolling) → Blank tube & rarr; Heat treatment & rarr; Straightening & rarr; Hydrostatic test (flaw detection) → Mark & rarr; Warehousing.

Stainless steel is a common steel in stainless steel, also known as 188 stainless steel. It is characterized by high temperature resistance, excellent processing performance and good toughness, stainless steel plate, stainless steel coil and other building materials. As a very important building material, stainless steel is widely used in industry, construction industry, home decoration industry and food and medical industry. It is one of the indispensable materials in life! So what items are made of stainless steel in our life? Let's have a look!

The petrochemical industry, has a great demand for stainless steel pipes. Stainless steel pipes are mainly used in this industry, including, 32, 34317l, etc., with an outer diameter of about ¢ 18 - ¢ 610 and a wall thickness of about 6mm-50mm (generally medium and low pressure transmission pipes with a specification of more than & phi; 159mm). The specific application fields are: furnace pipes, material transmission pipes, heat exchanger pipes, etc.

Let PS be the external force at the yield point s and fo be the cross-sectional area of the sample, then the yield point & sigma; S = PS / fo (MPA),Soft stainless steel strip, MPa is called MPa, equal to n (Newton) / mm (MPA = 106pa, PA: Pascal = n / M

Welcome calls .High temperature oxidation resistance stainless steel plates have high temperature oxidation resistance, but the oxidation rate will be affected by inherent factors such as environment and product form.

1: stainless steel plate: it can be divided into cold-rolled plate and hot-rolled plate. Its surface has bright surface, fog surface and matte surface. It is commonly known as stainless steel plate, including 2B plate and Ba plate. In addition, it can also be plated with other light colors according to customer requirements. The main specifications of plates are: 1m * 1m 1m * 2m, 22m * 44m, 5m * 3M, 5m * 6m. If customer demand is large, we can cut them according to customer size. In addition, we can replace wire drawing plate, anti sliding plate and electroplating plate

The difference between duplex stainless steel plate and ferritic 410 stainless steel plate: the comprehensive mechanical properties are better than ferritic stainless steel, especially the plastic toughness, which is not as brittle as ferritic stainless steel.

After the pipeline is installed and the pressure test is qualified, it is better to wash with low chloride ion water and disinfect with 0.03% potassium permanganate.

Quality department.L stainless steel pipe has become a very popular material in the market because of its many advantages. Today, Xiaobian will tell you in detail about L stainless steel pipe installation technology.

Adjust the ratio of austenite forming elements to ferrite forming elements in the steel to make it have austenite + ferrite dual phase structure, in which ferrite accounts for 5% - 12%. This dual phase structure is not easy to produce intergranular corrosion.

Batch size: a small number of single batch products will affect the unit price.

.(VI) the growth rate of fixed asset investment in the iron and steel industry dropped significantly. From 2013 to June, the investment in fixed assets in the iron and steel industry was 303.5 billion yuan a year-on-year increase of 3%, of which the investment in ferrous metal smelting and rolling was 235.6 billion yuan, a year-on-year increase of 3%,Stainless steel round pipe drilling, down 1 percentage point from the same period in 2012; The investment in ferrous metal mining and dressing was 67.9 billion yuan, a year-on-year increase of 8% and the growth rate fell sharply by 15 percentage points.

  SPHCSPHC—& mdash; In the first place, s is the abbreviation of steel, P is the abbreviation of plate, h is the abbreviation of hot heat, and C is the abbreviation of commercial. It generally represents hot-rolled steel plate and strip.

In addition to stress corrosion resistance, professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe have stable, safe and reliable performance and can be maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. Other local corrosion resistance properties are better than ferritic stainless steel.
