Title: Innovations in Pipe Coating: The Contributions of Inventor Sven Sjoberg

Introduction

Sven Sjoberg, an accomplished inventor based in Vasa, Finland, has made significant contributions to the field of pipe coating technologies. With a portfolio that includes three patents, Sjoberg's work focuses on innovative methods and apparatuses aimed at enhancing the durability and effectiveness of coated pipes.

Latest Patents

Sjoberg's latest inventions highlight his expertise in coating methods. The first patent details a novel method of coating pipes or pipe sections. This method involves applying a curable first polymer, such as epoxy, onto the pipe's surface. The first polymer can be partially cured or left uncured to create a reactive layer. Subsequently, the pipe is heated, and a second polymer (e.g., polyolefin) is applied directly to this reactive layer, resulting in a robust protective coating. Notably, the heating process can occur in two steps to ensure the first polymer remains reactive until the second polymer is applied.

His second patent introduces an apparatus and method for coating pipes. This innovative apparatus features an applicator for applying polymer melt, a roller for pressing the polymer onto the pipe, and a mechanism for circumferentially moving both components around the pipe's periphery. Additionally, the invention includes a drive that rotates the roller during its movement, which enhances the quality of coatings applied to field joints of steel pipes.

Career Highlights

Throughout his career, Sjoberg has worked with prominent companies such as Uponor Infra Oy and KWH Pipe Ab. His extensive experience in the industry has contributed to the practical applications of his inventions, making him a notable figure in the realm of pipe coating technology.
