1. The uses of large-diameter stainless steel pipes can be divided into oil well pipes (casing, oil pipes, drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structural pipes, hydraulic support pipes, gas cylinder pipes, geological pipes, and chemical pipes (high-pressure fertilizers). pipes, petroleum cracking pipes) and ship pipes, etc.
2. The thicker the wall thickness of the solution, is more cost-effective and sensible, and the thinner the wall thickness, its processing cost will appreciate greatly;
3. The product process determines its limitations, from the low precision of general seamless steel pipes: uneven wall thickness, low brightness tube appearance, high cost of fixed length, and the appearance of pitting corrosion, black spots are difficult to remove Walk;
4. Detection and plastic must be processed offline. So it’s a higher pressure, higher strength, mechanical structural wood that reflects its superiority.
5. The corrosion resistance of large diameter stainless steel welded pipe depends on the alloy components contained in the steel. Chromium is the basic component of corrosion-resistant stainless steel. About 12% of the chromium is in steel. Chromium interacts with oxygen in the corrosive medium to form a thin oxide film (passivation film) matrix on the surface of the steel, which can prevent further corrosion of the steel. To remove chromium, common alloy components of stainless steel seamless steel tubes you will find nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. To meet the specifications of the different use of stainless steel structure and performance. Reducers, and steel pipe fittings, are widely utilized in various industries to provide the flexibility to connect joined sections of pipe in several installations. A reducer can connect two pipes of different diameters with one fitting. Tube reducers are readily available within imperial and metric sizes depending on the commodity fittings produced for end use.
Advantages of large diameter stainless steel pipe:
1. Welded steel pipes are produced continuously online. The thicker the wall thickness, the greater the investment in the unit and welding equipment, and the less economical and practical it is. The thinner the wall thickness, the corresponding decrease in its input-output ratio.
2. The technology of this product ensures that generally welded steel pipes have high precision, uniform wall thickness, and high internal and external brightness (the surface brightness of the steel pipe is determined by the surface grade of the steel plate), and can be arbitrarily cut to length. Therefore, it embodies its economy and aesthetics in high-precision, medium- and low-pressure fluid applications.
3. The production process of welded steel pipe is simple, the production efficiency is high, the cost is low, and the development is rapid. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Welded pipes with larger diameters can be produced from narrower billets, and welded pipes with different diameters can also be produced from billets of the same width. However, compared with straight seam pipes of the same length, the weld length is increased by 30 to 100%, and the production speed is lower. Therefore, smaller-diameter welded pipes mostly use straight seam welding, while large-diameter welded pipes mostly use spiral welding.
