The leading supplier and manufacturer of the most versatile SS 304H EFW Pipes is none other than Silver Tubes. Our offered pipes are recommended in a wide variety of applications due to its impressive manufacturing and characteristics. We offer them in desired thickness, length, surface finish and width that our customers demand. Our pipes are secured and tested to ensure the performance, strength, categorical qualities of pipes that satisfy our esteemed clients. We fabricate the pipes to meet the needs of the customer. Our wide choice of alloy also ensures that pipes are as per the needs of the industries.
Manufacturing process:-
The process begins with the production of ingots from the raw material. In the next step skelp is used to prepare welded pipe of desired specifications. The unwinding machines unwound the pipe followed by a heating process. It undergoes grooved rollers that make the edges curl. Welding electrodes are then used to weld the unwelded pipe. A tight weld is ensured through this process where pressure is applied to tightly join the ends.
Further processing is done to ensure the final production of SS 304H EFW Pipes.
Properties of SS 304H EFW Pipes:-
The EFW pipes get the properties from the grade 304H. High carbon content makes the pipes more resistant against heat. This makes the pipes higher in yield strength, greater in both short and long term creep strength. Due to this reason, the EFW pipes are not only versatile but also economical. The corrosion resistant abilities of EFW pipes make a suitable choice for general purpose applications. The chemical composition is responsible for these properties in the pipes. The mechanical resistance, heat bearing ability, weldability, oxidation resistance, and corrosion resistance make it an all rounder pipe.
SS 304H EFW Pipes hold importance in applications in automobile, industrial production, construction, and other sectors. Home and commercial applications are the most common area of applications.
