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

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.

Q:What are the cutlery production methods using stainless steel scrap?: There are several cutlery production methods that utilize stainless steel scrap as a raw material. One common method is the melting and casting process. In this method, the stainless steel scrap is melted down in a furnace to create molten metal. The molten metal is then poured into molds to create the desired cutlery shapes. This process allows for the recycling of stainless steel scrap into new cutlery items. Another production method is the powder metallurgy process. In this method, stainless steel scrap is first crushed into fine particles or powder. The powder is then compacted into the desired shape using high-pressure machinery. The compacted powder is then heated in a furnace to bond the particles together and form a solid cutlery item. This method is often used for producing high-quality and intricate designs of cutlery. Additionally, there is the forging process, which involves heating the stainless steel scrap and shaping it through hammering or pressing. This method is commonly used for producing high-end and durable cutlery items. The stainless steel scrap is heated to a specific temperature and then hammered or pressed into the desired shape. The process of forging improves the strength and durability of the cutlery. Overall, these production methods allow for the effective utilization of stainless steel scrap in the production of cutlery. By recycling and repurposing scrap materials, these methods contribute to sustainable and environmentally-friendly manufacturing practices.

Q:How is stainless steel scrap formed into new products?: Stainless steel scrap is formed into new products through a process called recycling, where the scrap is collected, sorted, and cleaned. It is then melted down in a furnace and transformed into molten stainless steel. This molten steel is cast into various shapes, such as bars, sheets, or coils, depending on the desired final product. These new stainless steel products can be further processed and fabricated to meet specific requirements in industries like construction, automotive, or manufacturing.

Q:What are the heat resistance properties of stainless steel scrap?: Stainless steel scrap generally exhibits excellent heat resistance properties due to its high chromium content, which forms a protective oxide layer on the surface. This oxide layer helps prevent oxidation and maintains the integrity of the scrap even at high temperatures.

Q:Stainless steel 304. How much is the scrap now?: Are crap, now the bar prices are more than ten, only six or seven pieces of scrap prices

Q:How is stainless steel scrap used in the production of kitchen sinks?: The production of kitchen sinks heavily relies on stainless steel scrap. Firstly, various sources such as industrial waste, discarded appliances, and manufacturing leftovers are tapped to collect stainless steel scrap. Subsequently, this scrap is meticulously sorted and processed to eliminate impurities, ensuring the resulting stainless steel meets high-quality standards. Once the stainless steel scrap is purified, it undergoes melting in a furnace and is shaped into sheets or coils. These sheets become the primary material for manufacturing kitchen sinks. By employing specialized machinery, the stainless steel sheets are cut and molded into the desired sink design. The subsequent stage involves the welding or joining of different sink parts. Stainless steel scrap can also be utilized during this phase as filler material for welding joints. This integration helps uphold the sink's integrity and strength, guaranteeing its long-lasting durability. Moreover, stainless steel scrap can be integrated into the production of sink accessories such as drain baskets or bottom grids. These accessories are typically made from smaller pieces of stainless steel obtained from scrap materials. By incorporating stainless steel scrap into the manufacturing of these accessories, waste is minimized, and the demand for new raw materials is reduced. All in all, stainless steel scrap plays a crucial role in the production of kitchen sinks. It not only aids in waste reduction and sustainability but also contributes to the final product's strength, durability, and aesthetic appeal.

Q:How can stainless steel scrap be processed to remove impurities?: Stainless steel scrap can be processed to remove impurities through various methods such as sorting, magnetic separation, screening, and chemical treatments. Sorting involves separating different types of stainless steel scrap based on their composition. Magnetic separation uses magnets to separate ferrous impurities from the stainless steel scraps. Screening helps in removing larger impurities by passing the scrap through a mesh or sieve. Chemical treatments involve using acids or other chemicals to dissolve and remove impurities from the stainless steel scrap. These processes help in ensuring the purity and quality of the final stainless steel product.

Q:How is magnetic stainless steel scrap separated?: Magnetic stainless steel scrap can be separated using various methods, with the most common being magnetic separation. This process utilizes the magnetic properties of stainless steel to separate it from other materials. In magnetic separation, a magnetic field is applied to the mixture of stainless steel scrap and other materials. Since stainless steel is ferromagnetic, meaning it is attracted to magnets, it will be pulled towards the magnetic field. On the other hand, non-magnetic materials such as aluminum, copper, or plastic will not be affected by the magnetic field and will remain in the mixture. There are different types of magnetic separators used to separate stainless steel scrap, depending on the desired level of purity. One common type is the magnetic drum separator, where a rotating drum with a magnetic field attracts and separates the stainless steel scrap from the rest of the materials. Another type is the magnetic pulley, which uses a magnetic field to attract the stainless steel scrap as it passes over the pulley. In addition to magnetic separation, other techniques such as eddy current separation or density separation can be used to further refine the separation process. Eddy current separation uses a magnetic field to induce electrical currents in conductive materials, allowing the separation of non-ferrous metals like aluminum from the stainless steel. Density separation, on the other hand, relies on the difference in density between stainless steel and other materials to separate them. Overall, magnetic separation is the primary method used to separate magnetic stainless steel scrap from other materials. It is an efficient and effective process that allows for the recovery and recycling of valuable stainless steel while reducing waste and promoting sustainability.
