Hi-tech Metal & Tubes is a manufacturer and distributor of these products. The ASTM A53 Grade B ERW Pipes is electric resistant welded and the size could range up to 100 inches in some cases for the ERW pipes. The usual range is 1/8 inches to 26 inches in diameter. The ASTM A53 Grade B Schedule 40 is one of the most used schedules because of the medium level pressure containment capacities. The pipes are used in water supply, irrigation, sea water and waste water management systems alike. The corrosion resistance is low compared to other alloys, but the toughness and wear and tear resistance are higher. Our ASTM A53 Grade B Seamless Pipes can be used with high precision in applications making it preferable in narrow spaced applications for less processing while installation. The A53 Gr B Erw Pipes is stronger because of the manufacturing process. The A53 Welded Pipes is used in applications where excessive welding is expected. We encourage our customers to forward any inquiries and custom orders to us.
