Application Seamless steel tube with hollow section, a large number of pipeline used for conveying fluid, such as oil, natural gas, gas, water and some solid materials pipeline. It is widely used in the manufacture of structural and mechanical parts, such as oil drill pipe, automobile transmission shaft,bicycle frame and steel scaffolding used in construction. Characteristics of Seamless Boiler Tubes: High-Temperature Resistance: Seamless boiler tubes are manufactured from materials that can withstand high temperatures generated in boiler systems. Common materials used for seamless boiler tubes include carbon steel, alloy steel, and stainless steel. These materials offer excellent heat resistance, ensuring the tubes can handle the extreme temperatures and thermal stresses associated with boiler operations. Seamless Construction: Seamless boiler tubes are produced using a seamless manufacturing process, which involves heating a solid steel billet and then piercing it to form a hollow tube. This seamless construction eliminates the presence of welds or joints, which can be potential weak points in the tube. The absence of welds enhances the strength and integrity of the tubes, making them more reliable in high-pressure and high-temperature environments. Corrosion Resistance: Seamless boiler tubes are often made from materials with good corrosion resistance properties. Stainless steel and certain alloy steels, such as chrome-molybdenum (chrome-moly) steel, offer excellent resistance to corrosion and oxidation at elevated temperatures. This corrosion resistance helps to maintain the integrity of the tubes, ensuring long-term reliability and minimizing the risk of failure or leaks. Dimensional Precision: Seamless boiler tubes are manufactured with precise dimensions to meet the requirements of boiler systems. They are available in various sizes, diameters, and thicknesses, allowing for customization to specific project needs. The dimensional precision of the tubes ensures proper fit and compatibility with boiler components and facilitates effective heat transfer. High Pressure Resistance: Seamless boiler tubes are designed to withstand high-pressure conditions commonly found in boiler systems. They are engineered to handle the internal pressures generated by the steam or fluid circulating within the boiler. The tubes' strength and durability enable them to withstand the stress and pressure without deformation or failure, ensuring safe and efficient operation.

Inconel 625 is also known as the UNS N06625, Nr.2.4856, N06625, NC22DNb Inconel 625 is a Ni-Cr base solid solution reinforced deformation superalloy with chromium, molybdenum and niobium as the main sosoloid strengthened elements. The maximum operating temperature is 950℃. The alloy has good tensile strength and fatigue resistance from low temperature to 980℃ and has good processing and welding technicality. The alloy has excellent corrosion resistance, oxidation resistance and stress corrosion resistance in salt spray atmosphere. Alloys have been used in the manufacture of aerospace engine casings, guide blades, mounting edges and barrels, fuel pipelines and etc components. The corrosion rate of the alloy is very low in both Marine and non-marine atmospheres and its corrosion resistance to seawater is very good. The alloy is resistant to the corrosion of various salting and has good resistance to the corrosion of nitric acid and phosphoric acid. It also has considerable resistance to the corrosion of hydrochloric acid and low concentration sulfuric acid when heated below boiling point. The aging hardening of the alloy after long-term use at 550℃~700℃ can lead to a decrease in the alloy plasticity . The main products are sheet, bar, pipe, wire, strip and forgings.

Square and rectangular pipe is a name for square pipe and rectangular pipe, that is, steel pipes with equal and unequal side lengths. It is made of strip steel that has been processed and rolled. Generally, the strip is unpacked, flattened, coiled, welded to form a round tube, and then rolled into a square tube from the round tube and then cut to the required length. The usual delivery length of square and rectangular tubes is 4000mm-12000mm, mostly 6000mm and 12000mm. The square rectangular tube is allowed to deliver short-length and non-fixed-length products not less than 2000mm, and it can also be delivered in the form of an interface tube, but the buyer should cut off the interface tube when using it. The weight of short-length and non-fixed- length products shall not exceed 5% of the total delivery quantity, and for square and rectangular pipes with a theoretical weight greater than 20kg/m, shall not exceed 10% of the total delivery quantity. Process classification According to the production process, square and rectangular pipes are divided into: hot-rolled seamless square pipes, cold- drawn seamless square pipes, extruded seamless square pipes, and welded square pipes. 1. According to the process - arc welded square tube, resistance welded square tube (high frequency, low frequency), gas welded square tube, furnace welded square tube 2. According to the welding seam - straight seam welded square tube, spiral welded square tube. Material classification The square tube is divided into: ordinary carbon steel square tube, low alloy square tube. 1. Common carbon steel is divided into: Q195, Q215, Q235, SS400, 20# steel, 45# steel, etc. 2. Low alloy steel is divided into: Q345, 16Mn, Q390, ST52-3, etc. Production Standard Classification According to the production standard, the square tube is divided into: national standard square tube, Japanese standard square tube, British standard square tube, American standard square tube, European standard square tube, and non- standard square tube.
