Steel Pipes manufacters and Exports huge range of ERW Galvanized Steel Tubes & Steel Pipes. For pipes or tubes size 8 inch (219 mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks connected to the secondary of a revolving transformer assembly. The copper disk electrodes make contact on each side of the seam and temperature is raised to the welding point. Outside flash is removed by a cutting tool as the tube leaves the electrodes, inside flash is removed either by an air hammer or by passing a mandnel through the welded tube after the tube has been cooled. This is termed as Electric Resistance Welded or ERW tube/pipe.

ERW pipes are used in Water Pipelines, Agriculture and Irrigation (Water Mains, Sewerage Systems, Industrial Water Lines, Plant Piping, Deep Tube-Wells & Casing Pipes). Other popular application area includes usage in gas pipe lines (pipe lines for natural gas, LPG and other non-toxic gases). The SW is meant for shallow water applications This could be in a canal, natural stream, culvert, or pipe.

Q: Are stainless steel strips resistant to atmospheric corrosion?
Yes, stainless steel strips are resistant to atmospheric corrosion. Stainless steel contains chromium, which forms a protective layer on the surface when exposed to oxygen. This layer, known as a passive film, acts as a barrier that prevents further corrosion from occurring. Additionally, stainless steel also contains other alloying elements such as nickel and molybdenum, which further enhance its resistance to atmospheric corrosion. Therefore, stainless steel strips are highly resistant to rust, tarnish, and other forms of atmospheric corrosion, making them an ideal choice for various applications exposed to outdoor environments.
Q: How do I prevent galvanic corrosion on stainless steel sheets?
To prevent galvanic corrosion on stainless steel sheets, there are several measures you can take: 1. Ensure proper alloy selection: Choose a grade of stainless steel that is less prone to galvanic corrosion. Grades such as 316 and 317 are more resistant to corrosion compared to 304 stainless steel. 2. Separate dissimilar metals: Avoid direct contact between stainless steel sheets and other metals, especially those with a higher potential for galvanic corrosion. If contact is necessary, use insulating materials such as gaskets or rubber pads to separate the metals. 3. Use protective coatings: Apply protective coatings or paints specifically designed for stainless steel to create a barrier and prevent galvanic corrosion. These coatings act as a sacrificial layer, shielding the stainless steel from direct contact with the corrosive material. 4. Use isolation materials: Install insulating materials between stainless steel sheets and other dissimilar metals. These can include plastic washers, insulating tape, or non-conductive gaskets to prevent direct electrical contact and subsequent corrosion. 5. Proper maintenance: Regularly clean and inspect stainless steel sheets to remove any contaminants or foreign substances that could promote corrosion. Avoid using abrasive cleaners or tools that could damage the protective layer of the stainless steel. 6. Electrochemical protection: Implement cathodic protection techniques, such as using sacrificial anodes or impressed current systems, to provide an external source of electrons that can counteract galvanic corrosion. These methods help shift the corrosion potential of the stainless steel sheets to a more passive range. By following these preventive measures, you can significantly reduce the risk of galvanic corrosion on stainless steel sheets, ensuring their longevity and maintaining their structural integrity.
Q: What are the standard sizes available for stainless steel channels?
Standard sizes available for stainless steel channels vary depending on the specific industry and application. However, stainless steel channels generally come in a range of standard sizes. These sizes are typically measured in terms of height (H), width (W), and thickness (T). In the architectural and construction industry, standard sizes for stainless steel channels may range from 1 inch by 1/2 inch (25mm x 12mm) up to 8 inches by 2-1/2 inches (203mm x 64mm). These channels may have varying thicknesses, such as 1/8 inch (3mm), 3/16 inch (4.8mm), or 1/4 inch (6.4mm). For industrial and manufacturing applications, stainless steel channels may have larger dimensions. Common standard sizes for industrial channels can range from 3 inches by 1-1/2 inches (76mm x 38mm) up to 12 inches by 20 inches (305mm x 508mm). These channels may also have varying thicknesses, such as 1/4 inch (6.4mm), 3/8 inch (9.5mm), or 1/2 inch (12.7mm). It is important to note that these sizes are just examples and may vary depending on the manufacturer and specific requirements of a project. Additionally, custom sizes can be fabricated to meet unique specifications if standard sizes do not suffice.

Q: What is the difference between 304LN and 316LN stainless steel angles?
The main difference between 304LN and 316LN stainless steel angles is the chemical composition and their respective corrosion resistance properties. 304LN stainless steel angles have a higher content of chromium and nickel, which provides good resistance to corrosion and oxidation in various environments. However, they may be more susceptible to chloride-induced stress corrosion cracking compared to 316LN stainless steel angles. On the other hand, 316LN stainless steel angles contain molybdenum in addition to chromium and nickel, which enhances their resistance to pitting and crevice corrosion, especially in chloride-containing environments. They are commonly used in marine and coastal applications where exposure to saltwater or other corrosive substances is frequent. In summary, while both 304LN and 316LN stainless steel angles offer good corrosion resistance, 316LN stainless steel angles provide superior protection against pitting and crevice corrosion in more aggressive environments.

Q: How do I prevent stress corrosion cracking on stainless steel sheets?
To prevent stress corrosion cracking on stainless steel sheets, there are several measures you can take: 1. Choose the right stainless steel grade: Use a stainless steel grade that is resistant to stress corrosion cracking (SCC). Common grades like 304 and 316 have good resistance to SCC, but some specific applications may require higher alloyed grades such as duplex or super duplex stainless steels. 2. Avoid exposure to corrosive environments: Limit the exposure of stainless steel sheets to environments that are known to cause stress corrosion cracking, such as chloride-rich or acidic environments. If exposure cannot be avoided, consider using protective coatings or barriers to shield the stainless steel from these corrosive elements. 3. Control applied stress levels: Avoid subjecting the stainless steel sheets to excessive mechanical or thermal stresses. High tensile stresses can promote the initiation and propagation of stress corrosion cracking. Proper design and fabrication techniques should be employed to ensure even stress distribution and minimize stress concentrations. 4. Maintain proper surface condition: Ensure that the stainless steel sheets are free from surface contamination or defects that can act as initiation sites for stress corrosion cracking. Regular cleaning and inspection of the sheets to remove any contaminants or corrosion products is crucial. 5. Use inhibitors or cathodic protection: In certain cases where exposure to corrosive environments is unavoidable, the use of corrosion inhibitors or implementing cathodic protection techniques can help mitigate stress corrosion cracking. These methods work by reducing the corrosive activity on the stainless steel surface. 6. Proper handling and storage: During transportation and storage, care should be taken to avoid excessive bending, vibration, or exposure to corrosive substances. Stainless steel sheets should be stored in a clean and dry environment to prevent any potential surface contamination. Overall, a combination of material selection, environmental control, stress management, surface maintenance, and proper handling can effectively prevent stress corrosion cracking on stainless steel sheets. It is advisable to consult with material experts or engineers to analyze the specific application requirements and recommend the most appropriate preventive measures.
