What constitutes the Heat Affected Zone (HAZ)? The Heat Affected Zone (HAZ) refers to the region in a metal where melting hasnt occurred, yet its properties have been altered due to exposure to elevated temperatures during welding.
2024Preheating before welding is a process of appropriately heating the local and overall parts of the workpiece before welding. Its purpose is to reduce the cooling rate of the weld joint, avoid the formation of hardened structures
2024The new high-fin heat exchange tube provides a structure that integrates the fins with the tube body to eliminate contact thermal resistance between the tube body and the root of the helical fins
2024"Enhanced Surface Tubes" typically refers to heat exchanger tubes that have been modified to improve their heat transfer efficiency. These modifications are often done to increase the surface area available for heat transfer.
2024This article relates to a type of H-type finned tube, particularly focusing on an axially penetrating H-type finned tube and its heat exchange tube bundle, which is applicable to various types of heat exchange and heating equipment in industries
