The Seamless Pipes and Tubes manufacturer offers a variety of tubular products with high quality and a range of diameters, wall thickness, and material grade to satisfy the high standards of industrial, structural, and pressure piping. The Seamless Pipe Weight Chart in KG, MM, PDF could be considered a very essential reference guide to the engineers, contractors, fabricators and procurement professionals when planning and selecting materials to be used in the project. The manufacturers provide other sizes, like Alloy Steel Seamless Tubes, stainless steel, and Carbon Steel Seamless Pipes that can be used in the high-pressure and high-temperature services. Proper weight data will be used in guessing the amount of material, transportation budget and calculation of structural loads.


The Seamless Pipe Weight Chart contains comprehensive information about the pipe dimensions, outside diameter, wall thickness and weight of the meter of the pipe of different schedules and metric sizes. The seamless pipes are characterized by the manufacturing type (hot rolled and cold drawn), pressure ratings, and international designation; ASTM, ASME, EN, DIN, and IS. Seamless pipes have a superior mechanical strength, corrosion resistance and service life compared to welded joint pipes because of their uniform structure and the lack of a welded joint. They are thus used in oil and gas pipelines, boilers, heat exchangers, power plants, chemical processing units, and hydraulic systems.
