Manufacturing Processes of Seamless Pipes, Straight Seam Welded Pipes and Spiral Welded Pipes
This article introduces the core manufacturing processes of three mainstream steel pipes: seamless pipe, straight seam welded pipe, and spiral welded pipe. It compares the advantages and disadvantages of the three, clarifies the differentiated application scenarios of seamless pipe, which is suitable for harsh working conditions; straight seam welded pipe, which balances efficiency and medium- and high-pressure requirements; and spiral welded pipe, which is mainly used for low-cost production of medium and large diameter pipes. It also demonstrates the complementary application pattern determined by the three processes.
A Complete Guide to Structural Decomposition and Core Knowledge of Common Fire Pumps
This guide comprehensively elaborates on the core knowledge of common fire pumps, including their core specification requirements, classification standards (by structural form, drive method, and working principle), model interpretation, key parameters (pump head and flow rate), selection considerations, and daily maintenance points. It aims to provide systematic and practical technical guidance for relevant personnel in the selection, installation, operation, and maintenance of fire pumps, ensuring the safe and stable operation of fire water supply systems in emergency scenarios.

The Core Value of UL Listed in Fire Protection Applications
Fire safety is the last line of defense for lives and property, and fire product reliability defines this line’s strength. As a global fire safety benchmark, UL Listed offers far more than compliance—it ensures product and system performance via rigorous testing, strict standards, and full-chain oversight. Meeting UL requirements is now a non-negotiable safety baseline for fire products in key scenarios like building fire safety and emergency response
Application of Cables in the Fire Protection Field
Per fire safety regulations, fire equipment’s emergency power wiring needs fire resistance, with qualified fire-resistant cables chosen by equipment type. These cables sustain power in high-temperature fires, linking emergency lighting and fire pumps in crowded areas (high-rises, subways, hospitals). Flame-retardant cables, with fire-retardant barriers, slow/stop fire spread, fitting commercial complex wiring. Cable trenches (key power channels) use intelligent solutions (e.g., auto fire suppression) to protect mine/port power rooms. Cables also support fire power distribution (380V/220V AC, 36V/24V DC) and transmit fire alarm/linkage signals. Briefly, they are vital for fire protection, impacting enterprise safety, social stability and public well-being.

Core of New Fire Pump National Standard: Diesel Engine Power Must “Fully Cover”!
Introduction and Interpretation of the New GB 6245 National Standard.One of the most pivotal changes in GB 6245-2025 is the requirement that diesel engine power must cover every point on the pump performance curve. The exemption clause for 1.5 times flow rate in the old regulation has been removed, meaning that any overload at a single operating point will create safety hazards and result in acceptance failure. The industry refers to this as “no-overload” operation. PumpMac takes you to an in-depth interpretation of the new regulation requirements.
