Large Diameter Stainless Steel Tube

Large diameter stainless steel tube is a type of stainless steel tube with a larger outer diameter that is commonly used in applications such as fluid transportation and structural support. Large-diameter stainless steel pipes have excellent corrosion resistance, strength and lifespan, so they are widely used in many fields, such as chemical industry, petroleum, natural gas, pharmaceuticals, food, environmental protection, nuclear energy, etc. Generally speaking, according to the different manufacturing processes, large diameter stainless steel pipe can be divided into two types: seamless pipe and welded pipe. There are various production processes for large diameter stainless steel pipe, and different processes are suitable for different product specifications and applications. And the production process mainly has two methods of hot rolling and hot expansion. In addition to the two methods of hot rolling and hot expansion, the production process of large diameter stainless steel pipe also includes cold drawing and extrusion and other methods.

    Introduction

    The models of large-diameter stainless steel tubes are usually named and identified according to their outer diameter, wall thickness, connection method and other parameters. The following are some common large-diameter stainless steel pipe models:

    1. DN model: DN (nominal diameter) is used to indicate the diameter of pipes, valves, flanges, pipe fittings, seals, etc. Common DN models include DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, etc.

    Model indication: A stainless steel pipe is marked DN15. According to the standard size table, you can know that its inner diameter is 15mm, its outer diameter is about 23mm, and its wall thickness is about 4mm.

    2. Specifications and models: Depending on the inner diameter and outer diameter of the tube, the specifications and models are also different. For example, common specifications include φ15mm×1mm, φ20mm×1.2mm, φ25mm×1.5mm, φ32mm×1.5mm, φ40mm×1.5mm, etc.

    3. Pipe series: The pipe series refers to the ratio of the wall thickness of the pipe to the pipe diameter, which is usually used to indicate the load-bearing capacity of the pipe. Common tube series include SCH40, SCH80, SCH160, etc.

    4. Pipe specifications: Pipe specifications refer to the outer diameter and wall thickness of the pipe, and are usually used to indicate the size and quality of the pipe. For example, common pipe specifications include Φ114.3×4.76mm, Φ219×8mm, etc.

    Application
    1. Construction field: Large diameter stainless steel tubes can be used as water supply and drainage pipes, HVAC pipes and heating pipes.
    2. Environmental protection field: widely used to treat waste water and waste gas. For example, it can be used to make pipes, pumps and other components in wastewater treatment equipment to ensure the effectiveness and safety of wastewater treatment. At the same time, it can also be used to make flues, flue gas purifiers, etc. in flue gas treatment equipment, effectively reducing the pollution of waste gas to the environment.
    3. New energy field: Large diameter stainless steel tubes can be applied to heating network heaters in power plants, seawater desalination equipment, floor heating, industrial air conditioners, water supply heaters, batteries, etc.
