1. Product Overview

Product Name

76-660mm HFW Pipe Feed Factory Water Supply Circulation Pipeline

Core Standard & Product Positioning

This series of HFW high-frequency longitudinal welded steel pipes is manufactured strictly in accordance with GB/T 3091, EN 10219, ASTM A53 and industrial fluid pipeline specifications. Covering a complete outer diameter range of 76mm to 660mm, it is a professional dedicated pipeline tube for factory raw water supply, workshop cooling water circulation, industrial recycled water transmission and factory internal water supply pipe network. Adopting advanced HFW high-frequency induction welding technology and online stress relief treatment, the pipe body features uniform wall thickness, ultra-stable weld structure and excellent hydraulic performance. It perfectly adapts to 24-hour continuous cyclic water delivery, frequent water pressure fluctuation and long-term industrial operation conditions, solving common problems of ordinary pipes such as high flow resistance, easy leakage and short service life in factory water circulation systems.

Core Advantages for Factory Water System

Aiming at the operating characteristics of factory water supply and circulation systems including continuous operation, cyclic scouring and stable pressure delivery, this HFW welded pipe has targeted performance upgrades. The filler-free high-frequency welding process ensures integrated weld performance consistent with the base metal, effectively avoiding pipeline cracking and water leakage during long-term cyclic operation. The smooth burr-free inner wall greatly reduces water flow resistance and pump power consumption, improving factory water transmission efficiency and saving operating costs. With excellent structural stability and anti-fatigue performance, it resists long-term water flow impact and pressure fluctuation, ensuring stable and efficient operation of factory water supply and circulation pipe network all year round.
