The product range of Scorodite includes all types of Hastelloy C59/C4/H N Welded Tube for industries which require high durability, superior performances and exceptional quality. Hastelloy C59/C4/HN Welded Tube can be used for industrial processes using corrosive environments, performing fluctuating thermal loads and operating in hazardous service conditions. The alloy composition of Nickel, Chromium and Molybdenum allows for such an alloy to be constructed with a balanced microstructure capable of being used where both mechanical integrity and resistant to both oxidizing and reducing agents are required.

Hastelloy C59/C4/H N welded Tubes are manufactured via precision welding processes and are then heat treated to meet ASTM B619 and ASME SB619 specifications. Each of these grades has been developed with distinct properties. C59 is highly resistant to oxidation at elevated temperatures; C4 is very stable after extended exposure to elevated temperatures; HN provides strength enhancements as well as fine microstructure control.

All of these grades represent a category of material we consistently rely on in chemical production plants, power-generating facilities and ultra-pure processing operations. As one of the premier manufacturers of Hastelloy C59/C4/H-N Welded Tubes, we at Scorodite are proud to support our customers with quality production hasil C59, C4 and HN welded piping.

The welded Tubes made with Hastelloy C59/C4/H-N are comprised of nickel-based alloys, have smooth surfaces, have tight dimensional tolerances, and have uniform welding. They have very low corrosion rates when exposed to sulfuric acid, hydrochloric acid, phosphorus acid, or acetic acid. The addition of molybdenum increases the resistance to pitting, while the addition of chromium increases the resistance to oxidation. ASME grades have been aligned with the use of this alloy, providing excellent performance under pressure, putting Scorodite in the top tier of Hastelloy C59/C4/H-N welded Tube suppliers.

Hastelloy C59/C4/H-N welded Tubes provide excellent stability over a broad range of temperatures. They are resistant to stress corrosion cracking due to chlorides and have excellent mechanical strength when subjected to static and cyclical loads and forces. The welded joints are consistent, providing fewer downtime or maintenance issues. The alloy does not scale, and as such, it does not contaminate the fittings; therefore, the Tubes are suitable for applications that require clean piping systems. The welding characteristics make it easier to install Hastelloy C59/C4/H-N welded Tubes in complex piping systems. These characteristics further strengthen Scorodite's reputation as a trusted stockist of Hastelloy C59/C4/H-N welded Tubes.

In many different industries, end users have come to depend on the Tubes manufactured from Hastelloy C59 and C4 materials to produce consistently high-quality results over an extended period. The most notable example of how this has occurred is in the chemical processing industry. The Tubes are used to transfer corrosive fluids in a manner that maintains a high level of purity and provides the necessary resistance to corrosion. Similarly, in the petrochemical Industry, these types of Tubes are used in high-temperature reactors that experience continuous thermal cycling.

In addition, in the power generation sector, specifically in waste-to-energy facilities, these Tubes are utilized in heat recovery systems that contain oxidizing gases. In marine engineering, the systems utilizing these Tubes are exposed to seawater. It is critical that the Tubes have the proper pitting resistance to ensure that the systems operate reliably. In the pharmaceutical Industry, the equipment used in sterile processing will employ these Tubes in order to ensure the cleaning of the internal surfaces and to minimize potential cross-contamination of products.

Numerous International Standards Organizations have provided various designations for the Tubes manufactured from Hastelloy C59 and C4 materials. The American Society for Testing and Materials (ASTM) has defined these as ASTM B619 for welded Tube and ASTM B622 for seamless Tube. The American Society of Mechanical Engineers (ASME) has defined these as SB619 and SB622, respectively. The German standards (DIN) use two similar material groups; DIN 2.4610 for C4 and DIN 2.4605 for some related nickel alloys. ISO has identified the Tubes used in nickel alloy piping categories and assigned them to High Corrosion Resistance (HCR) classifications, thus enabling engineers to compare the technical requirements for each region.

At Scorodite, our commitment to quality and dimensional accuracy is unwavering. All products are subjected to hydrostatic testing to ensure proper pressure range, chemical paste analysis, and weld integrity assessment. The above procedures help ensure all Tubes will stand the test of time and continue to provide reliable service under demanding environments for extended periods of time.
