ST 37 Pipes

SA179 Tube Company is a leading supplier of DIN 2391 ST37 pipes, offering a versatile range in different standards, dimensions, and shapes. Composed of carbon, nitrogen, phosphorus, and sulfur, the ST37 Pipes are engineered for strength, corrosion resistance, and durability. 

With a minimum yield strength of 235MPa and a minimum tensile strength of 470MPa, these pipes provide high tensile and yield strength, making them suitable for applications demanding structural integrity. The pipes are available in various processing options such as hot rolled, cold rolled, cutting, grinding, machining, and forming operations. 

The dimensional range encompasses outer diameters from 4mm to 60mm, wall thickness ranging from 0.5mm to 8mm, and lengths up to 6000mm. Designed for wear and tear resistance, these pipes find applications in petroleum industries, oil and gas industries, food processing, chemical, power generation, transmission lines, and general-purpose piping applications. 

The ST 37 Steel Grade Seamless Pipe is known for its high impact strength, making it ideal for outdoor applications under high-impact conditions. 

ST37.2 is classified as low carbon steel, with a carbon content of up to 0.20%. This grade is extensively utilized in the manufacturing of structural applications and components due to its favorable properties. One notable product derived from ST37.2 steel is the ST37.2 Seamless Pipe, highly sought after for its exceptional features and versatility across a broad spectrum of applications.

The ST37.2 Seamless Pipe boasts remarkable attributes, including high tensile and yield strength, formability, workability, corrosion and oxidation resistance, weldability, and an extended service life. These features collectively contribute to the widespread demand for these seamless pipes in a diverse range of applications. Their suitability for use in both high and low-temperature conditions adds to their appeal.

One of the key strengths of ST37.2 Seamless Pipes lies in their ability to withstand elevated temperatures and pressures without succumbing to damage. This makes them reliable and resilient components for applications where performance under challenging conditions is crucial. Whether it’s for structural purposes or specific industrial applications, ST37.2 Seamless Pipes stand out as a preferred choice, delivering a combination of durability, adaptability, and longevity.
