Small-diameter stainless steel welded pipes have developed rapidly in recent years, bringing economic benefits to manufacturers

With the rapid development of my country's economic construction, the consumption of stainless steel continues to increase, and the demand for stainless steel pipes is also expanding, and the market prospects are promising. The market demand for stainless steel seamless pipes is manifested in basic industries, such as petroleum, chemicals, power generation, etc., and its demand accounts for one-third of the total consumption of stainless steel seamless pipes, as well as automotive, shipbuilding, construction and environmental protection industries. Greater demand.

Stainless steel welded pipes are currently mainly used in heat exchanger tubes, fluid pipes, pressure pipes, mechanical structure pipes, urban landscapes, and other industries, with annual consumption of about 700,000 tons. The demand for industrial stainless steel welded pipe is relatively high, and the production process is mature. At present, my country's annual industrial stainless steel welded pipe volume is about 150,000 tons, and some still need to be imported. From the domestic stainless steel tube products, the steel type is mainly austenitic steel; the product varieties are: seamless steel tubes including cold drawn tubes, cold rolled tubes, hot extruded tubes, centrifugal casting tubes, spinning tubes; welded tubes include : Welded pipes such as plasma welding, argon arc welding, submerged arc welding, light speed welding and high frequency welding. The stainless steel pipes that can be produced basically cover the varieties and specifications of various countries in the world, and the specifications and varieties of stainless steel special-shaped tubes also reach more than 100 kinds. , Product uses involve many fields of industry and civil use. However, in general, the domestic stainless steel pipes have a certain gap with the market demand in terms of varieties, specifications and quantities.

In recent years, there have been an increasing number of stainless steel welded pipe production companies, but few companies have reached the 5,000-ton output level, especially those that can produce stainless steel heat exchanger tubes and condenser tubes that require on-line solution annealing. In the southern region of China, there are only a few enterprises such as Zhejiang Jiuli, Jiangsu Wujin, and Taiwan Changyuan; in the northern region, there is only one enterprise such as Shandong Jinrunde Stainless Steel Pipe Co., Ltd., most of them are small factories with an annual output of less than 2,000 tons, and can only produce Several common specifications of ordinary welded pipe.

Welded steel pipe is referred to as welded pipe for short. It is usually a steel pipe made of steel or steel strip welded after being crimped by the unit and the mold. Welded steel pipe production process is simple, high production efficiency, many varieties and specifications, less equipment, but the general strength is lower than seamless steel pipe. Since the 1930s, with the rapid development of continuous production of high-quality strip steel and the advancement of welding and inspection technology, the quality of welds has been continuously improved, and the variety and specifications of welded steel pipes have been increasing, and they Heat exchanger spare tubes, decorative tubes, medium and low pressure fluid tubes, etc. have replaced seamless steel tubes.

Next, let's look at the characteristics of stainless steel welded pipe.

The small-diameter stainless steel welded pipe is produced continuously online. The thicker the wall thickness, the greater the investment of the unit and welding equipment, and the less economical and practical it is. The thinner the wall thickness, the lower the input-output ratio. Second, the technology of the product determines its advantages and disadvantages. Generally, the welded steel pipe has high precision, uniform wall thickness, and high brightness inside and outside the pipe (steel pipe determined by the surface grade of the steel plate) Surface brightness), can be arbitrarily sized. Therefore, it embodies its economy and aesthetics in high-precision, low- and medium-pressure fluid applications.

Hangao Tech (SEKO Machinery) continuous online bright annealing small-diameter heat exchanger stainless steel welded pipe production line precisely solves the aforementioned shortcomings of the old-style production equipment, making the production of stainless steel heat exchange pipes economical and practical. The process from steel strip to forming welding and bright annealing is completely done on the production line. Moreover, the welding process has added electromagnetically controlled arc stabilization, which effectively guarantees the quality of the weld seam and greatly improves the production efficiency.

Every time the finishing tube is rolled, it must go through the process of solution treatment. Ta ensure that the performance of the steel pipe meets the technical requirements. and to provide guarantee for the post-process processing or use. Bright solution treatment process of ultra-long seamless steel pipe has always been a difficulty in the industry.

Traditional electric furnace equipment is large,covers a large area, has high energy consumption and large gas consumption, so it is difficult for realize bright solution process. After years of hard work and innovative development, the use of current advanced induction heating technology and DSP power supply. Precision control of heating temperature to ensure that the temperature is controlled within t2C,to solve the technical problem of inaccurate induction heating temperature control. The heated steel pipe is cooled by "heat conduction"in a special closed cooling tunnel, which greatly reduces the gas consumption and is more environmentally friendly.
