ERW Line Pipe: The two ends of the flat steel are bent circularly with the help of rollers in a pipe machine. The welding is achieved by applying electric current at the joint, heating it to fuse. In this way, resistance-welded pipe is produced. This product is widely used in various industries such as aerospace, automotive, energy, and light industry.
Hera Çelik is a company with a wide product range and supplies resistance-welded pipe. We provide the most suitable product for our customers’ needs with our professional team in the shortest time. These products are customized according to the features of the area where they will be used. We gain our users’ approval with resistance-welded pipe, which meets quality standards and certifications.
Electric Resistance Welded Pipe Dimensions
The dimensions of electric resistance welded pipes vary according to the application area. These products, which have a wide range of applications, are produced with different technical and mechanical properties. Depending on the area of use, the outer diameter, wall thickness, and length of these pipes vary. The pipe offered by our company is prepared with the requirements suitable for the application area and project.
We ensure that we provide products with the correct mechanical properties, homogeneous, and reliable characteristics. The quality of the raw material used in the production of each product we supply is one of our top priorities. The resistance-welded pipe is made from high-toughness steel. By offering high-resistance, high-strength products to our users, we ensure they are satisfied with the service and the product they receive.
We provide users with the option of different coatings for electric resistance-welded pipes. In addition to various coating options, the ends of these pipes are also prepared in different forms such as plain-ended or welded-end, based on customer demands.
