Bolted connections are the primary assembly method in bridges and steel structure engineering, with high-strength bolts ensuring reliable fastening for steel structure joints, steel box girder splices, and foundation bearing connections. The quality of bolt tightening directly impacts the load-bearing capacity and service safety of the entire structure. Insufficient preload or uneven tightening can easily […]
Electric torque wrenches have a wide range of applications, including steel structure installation, the automotive parts industry, power infrastructure construction, bridge engineering, and the petrochemical industry. However, while some industries simply require basic bolt tightening and loosening, others demand greater precision. Which industries specifically require high-precision electric torque wrenches? High-precision electric torque wrenches are ideal […]
A common misconception in steel structure construction is that the longer the shank of a high-strength bolt, the more secure the connection; in reality, this is not the case. The load-bearing capacity of a high-strength bolt is not determined by the length of its shank; blindly increasing the length not only fails to enhance strength […]
Shandong Hanpu recently completed the shipment of an order for 40 torque wrenches destined for a domestic bridge project. The order comprised 20 electric torque wrenches, 20 lithium-battery torque wrenches, and two portable bolt torque testers. These tools are en route to the construction site, where they will provide reliable support for high-strength bolt fastening […]
Amidst the peak summer sales season, following an order for over 600 electric wrenches from a German client, Shandong Hanpu has ramped up production planning and is fully stocking key products, such as electric torque wrenches. As a specialized manufacturer of torque wrenches, Shandong Hanpu maintains bulk inventory across its entire product range, offering a […]
The seismic performance of high-strength bolts is not constant and can vary significantly depending on the temperature, humidity, medium, and vibration frequency of the environment. Understanding how they adapt to different conditions is key to ensuring the long-term stability of steel structure connections. Under different working conditions, there are noticeable differences in bolts’ resistance to […]
During the installation and maintenance operations of petrochemical pipelines, both torque wrenches and ordinary impact wrenches are commonly used tightening tools. These two types of tools are quite different, and the effectiveness of the operations also varies greatly. In the scenarios where petrochemical pipelines are used, the final tightening of the flange bolts of the […]
