Seamless pipes are pipes that are manufactured without a seam or weld, making them one continuous piece of metal. The process of creating seamless pipes involves extruding a solid steel billet through a piercing rod, followed by elongation and further processing to create a pipe with a uniform wall thickness and high tensile strength. The absence of a weld means that seamless pipes are free from weak points, offering enhanced durability and resistance to high pressure and extreme conditions... Read More
ERW pipes are made by welding steel coils together using an electric resistance welding process, resulting in a continuous, uniform pipe. This method creates a smooth, reliable product with a consistent wall thickness and a high level of structural integrity. The primary advantages of ERW pipes include their strength, flexibility, and ability to be manufactured in various sizes and thicknesses... Read More
EFW pipes are created through a fusion welding process that joins steel plates or coils using electric current to generate heat. This process produces pipes with a strong, continuous weld seam, ensuring that they maintain structural integrity and resist corrosion over time. EFW pipes are commonly used for applications where high pressure, extreme conditions, and durability are required... Read More
