Seamless Steel Pipe

Seamless pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless Steel Pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow pipe.


Galvanized seamless pipe

Characteristics of galvanized seamless pipe Light weight, easy to handle Because the galvanized seamless pipe itself is relatively light, the daily transportation and construction are very simple, which can save a lot of time and cost. Good corrosion resistance The corrosion resistance of seamless steel pipes is very good. They are resistant to acid, alkali, salt and atmospheric environment. Moreover, it is resistant to high temperature and impact, and does not need regular maintenance. Good physical and chemical properties Galvanized seamless pipe has very good physical and chemical properties, its tensile strength is more than 8 times stronger than ordinary steel, and its elastic modulus is also better than ordinary steel. Moreover, it also has good mechanical capabilities and is very easy for daily processing. Long term use will not deform, anti-static ability is good.


INCOLOY Alloy 825

Incoloy 825 is a nickel iron chromium alloy, which is widely used in petroleum, natural gas and chemical processing industries. It has good corrosion resistance and can operate at higher temperatures than most stainless steels.
