1. Fixed-length spiral steel pipes can be unbundled. 2. If the two ends of the spiral steel pipe are threaded, they should be protected by thread protectors. Apply lubricant or rust inhibitor on the thread. The two ends of the spiral steel pipe are broken, and the two ends can be equipped with nozzl
Large seamless pipe forming techniques mainly include: hot spinning method, heat extrusion method, hot piercing rolling method, including preparation of expanding method.

Corrosion in stainless steel is one of the most troublesome technical concerns for fabricators. Whether localized or widespread, corrosion takes many forms, depending on the particular service environment. Some common types are general corrosion, crevice corrosion, intergranular corrosion, pitting c
When a fabrication requires corrosion resistance and high performance, your foremost concern is its affordability. One metal that can meet this demand is ferritic stainless steel. Grades include AISI type 409, 11CfCb, 430, 436, 439, and 18CrCb, just to name a few. Whichever grade you choose, ferriti
