Frequently Asked Questions
Hot-dip galvanizing involves immersing the steel in molten zinc, creating a thicker, more durable layer that offers superior corrosion protection compared to the thinner layer produced by cold galvanizing.
Grades such as API 5L, Q345, and A53 are typically preferred for oil and gas applications due to their balanced strength and ductility under pressure.
Yes, we provide full customization services. Buyer's drawings or designs are available to ensure the pipes meet your specific project dimensions and requirements.
We offer various options including plain ends, beveled ends, grooved, threaded and coupling, all protected by plastic caps during transit.
Absolutely. Due to their high corrosion resistance and compliance with standards like ASTM A53, they are widely used in fire piping systems.
Depending on the order, we provide CE, AS4020, BSI, ANAB, and ISO9001 certifications to guarantee the quality and grade of the steel.
