Stainless Steel 317 Large Diameter Pipe

What are the key properties and characteristics of stainless steel 317 / 317L large-diameter pipes?

Stainless Steel 317 and 317L Large-Diameter Pipes possess several key properties and characteristics that make them highly desirable for various industrial applications. One of the most prominent features is their exceptional corrosion resistance. These pipes resist various corrosive environments, including acids, alkalis, and chlorides. This corrosion resistance is primarily attributed to the high levels of chromium, molybdenum, and nickel in the stainless steel composition.

Stainless steel 317 and 317L large-diameter pipes offer excellent strength and durability. They have higher tensile strength than many other stainless steel grades, allowing them to withstand high-pressure and high-temperature conditions. This strength also contributes to their ability to resist deformation, making them suitable for mechanical stress or structural integrity requirements applications.

How does stainless steel 317 / 317L compare to other stainless steel grades regarding corrosion resistance?

Stainless Steel 317 exhibits outstanding corrosion resistance, which sets it apart from many other stainless steel grades. Its composition includes a higher chromium, molybdenum, and nickel content, contributing to its exceptional resistance to various corrosive environments. In particular, stainless steel 317 demonstrates superior resistance to corrosion by sulfuric acid compounds and other acidic environments containing chlorides and halides.

Stainless steel 317L showcases exceptional corrosion resistance, favouring it among various stainless steel grades. Adding low carbon content to stainless steel 317L enhances its resistance to sensitization, a process that can lead to intergranular corrosion. That makes stainless steel 317L particularly advantageous in applications involving exposure to high temperatures, such as welding or heat treatment processes.

Stainless steel 317L's superior corrosion resistance extends to various corrosive media, including acids, alkalis, and chlorides. That, coupled with its ability to maintain its mechanical properties at elevated temperatures, makes it highly suitable for chemical processing, pharmaceuticals, and petrochemicals, where resistance to aggressive chemicals and high-temperature environments is crucial.

Forming

According to the name, the plate is bent into a "U" and then a "O" in succession. The lowering of the die starts the process of forming in the U-ing press. The side rollers move the crimped plate in the direction of the die. The O-ing press is then used to mould the U-shaped plate into a slit pipe. Working at up to 60,000 tonnes of pressure, this is precision work.

Two lower rolls and one higher roll bend the plate to the appropriate radius during the three-roll bending procedure. Different top roll diameters are employed, depending on the steel grade and necessary pipe diameter. Afterward, the crimping machine rounds the created edges.

Tack welding of the slit pipe

The open edges of the slit pipe are tacking welded together in shielding gas prior to submerged-arc welding. Frames (roller cages) are used for this, which precisely position the edges and prevent misalignment. Additionally, the continuous tack weld keeps the weld pool in place for subsequent submerged arc welding.

Pipe identification

material tracking throughout the entire production process. For identification each pipe is marked with a pipe production number. Additionally a line, marking the centre of the pipe, is the reference for late non-destructive testing of the weld seam.

Inside and outside welding

Two passes are used to attach the longitudinal edges. At the pipe ends, run-on and run-off tabs are positioned to stabilise the electric arc at the start and end of the welding process.

Outside welding is done after the inside welding has been completed. The tack weld pass has fused entirely. Up to five welding wires can be positioned in a line behind one another during submerged-arc multi-wire welding. Welding wire and flux, amperage, voltage, welding speed, wire spacing, wire diameter, the angle of the wires in relation to one another and the weld groove, as well as flux height and width, all affect how consistently good a weld is. A welding data monitoring system enables online manufacturing process monitoring.

X-ray weld inspection / Filmless radiography

Each seam is first visually inspected from the inside out. In addition to X-ray and manual ultrasonic testing, our internal quality checks also involve ultrasonic inspection of the whole seam.

When compared to traditional film-based approaches, the use of automatic picture evaluation software and image processing capabilities considerably increases the reliability of inspection and detection. Any ultrasonic signals are automatically and precisely verified. We take pride in being the only manufacturer of large-diameter pipes to use digital technology for all radiography examinations. We streamline the inspection procedure, record the findings, and keep track of any deviations for later follow-up.
