How seamless steel pipes are connected

Now, let's talk about the sealing connection method of seamless steel pipe. The main principle of the seamless steel pipe sealing connection method is that in a pipe fitting composed of a pipe fitting body and a sealing ring, the outer end of the connection of the pipe fitting body is conical, and the sealing ring can be made to have an annular groove on it. shape, and the height of the inner edge of the groove is smaller than the outer edge. This height difference creates a gap through which fluid can enter the groove. Therefore, under the action of fluid pressure, the inner edge of the sealing ring tightly surrounds the pipe, resulting in a self-sealing effect. The sealing ring can also be made of water-swellable rubber.

For water pipes, self-sealing also occurs due to water absorption and expansion. The conical inner end is connected with an annular groove in which a sealing ring with a self-sealing function under fluid pressure is installed. The outer end of the pipe joint is cylindrical, passes through the sealing ring and fits tightly, and its inner end has the same taper as the pipe body, with a small outer cone and a large inner cone, both passed through the adhesive forming the cone .
In this way, due to the self-sealing effect of the sealing ring, the bonding surface is separated from the water, preventing the "erosion" of hot water, and improving the hot water resistance of the bonded joint, making it suitable for hot water pipes. The sealing adhesive head using this sealing connection method is suitable for connecting with the pipeline.

Stainless steel plates are classified according to different organizational structures

Production of seamless steel pipes

Although stainless steel plates account for a relatively small proportion of world steel consumption, they are still vital to specific manufacturing industries such as the energy and food processing markets. At present, the global consumption of stainless steel plate materials is continuously increasing.

Production process of welded steel pipe

The development of steel pipe production technology began with the rise of bicycle manufacturing, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry, and The drilling and transportation of oil and natural gas have strongly promoted the development of the steel pipe industry in terms of variety, output and quality.

Steel prices have risen by more than a thousand steel companies generally turn losses into profits

Since the first half of last year, steel prices have begun to recover thanks to a series of measures such as supply-side reforms and elimination of backward production capacity. Taking rebar as an example, the average price on March 9 last year was 2475 yuan/ton, and on March 9 this year, it has risen to 3852 yuan/ton, an increase of 35%.

China Steel Association: Steel prices in the domestic market continued to rise slightly in September

According to data from the China Iron and Steel Association, in September, the domestic steel market demand was strong, and steel prices continued to rise. Affected by the rapid release of steel production capacity, pressure on the supply side has risen, and the price increase of steel has narrowed.
