Seamless Galvanized Pipe

Seamless Galvanized Pipe

Seamless galvanized pipes are designed to deliver exceptional performance in corrosive environments and are ideal for both industrial and structural applications. These pipes are manufactured without any weld seams, ensuring consistent wall thickness, superior strength, and better pressure resistance. They are then hot-dip galvanized, forming a uniform zinc coating that protects the steel from rust and corrosion, making them highly durable in outdoor or harsh conditions.

Available in a size range of ½” to 16” (15mm–400mm), with outer diameters (OD) starting from 1/8″ (5.15mm) up to a maximum of 24” (609.6mm) (DN600), these pipes are offered in various wall thicknesses from 0.4mm to 26mm, with schedule options such as SCH20, SCH40, STD, XS, SCH80, SCH160, and XXS. The maximum length available is 12 meters, and end treatments include plain, beveled, threaded, chamfered, or grooved ends, depending on application needs.

These galvanized pipes conform to ASTM A53 Grade A/B standards and are made from materials like Q195 (SS330, ST37), Q235 (SS400, S235JR), and Q345 (S355JR, ST52). They are widely used for low-pressure water, gas, and oil transportation, construction site installations, fencing, and scaffolding systems. The galvanized layer provides excellent corrosion resistance, especially in environments exposed to moisture or chemicals.

Importance of Seamless Galvanized Pipe

Seamless galvanized pipes are vital where long-term corrosion protection, mechanical strength, and easy installation are needed. The seamless body eliminates the weak points found in welded pipes, while the zinc coating ensures years of maintenance-free service, even in coastal, industrial, or high-humidity environments. These pipes also offer temperature resistance ranging from -20°C to 300°C, making them suitable for a wide variety of climates and installations.

Their ability to be installed and removed without permanent connections — often requiring only basic tools like an Allen wrench — makes them especially valuable for temporary scaffolding, portable water systems, or modular construction setups. With surface finish options like bare, black-painted, oiled, or anti-corrosion coatings, seamless galvanized pipes combine flexibility, strength, and longevity in one reliable solution.
