The explosion-proof tools developed by Hebei Zhongbo Explosion-proof Tools Group Co., Ltd. are made of copper alloy. The main products include explosion-proof hammer series, explosion-proof screwdriver series, explosion-proof wrench series, explosion-proof scissors series, explosion-proof Knife series, explosion-proof shovel series, explosion-proof crowbar series, and other types of explosion-proof mining tools. Due to the good thermal conductivity of copper and its almost carbon-free properties, when the tools and objects rub or impact, the heat is generated in a short period of time. Being absorbed and conducted, another reason is that copper itself is relatively soft, has good yielding properties during friction and impact, and is not easy to produce tiny metal particles, so we can hardly see sparks, so explosion-proof tools are also called spark-free tools.
The various German-made series of explosion-proof tools developed and produced by Hebei Zhongbo Explosion-proof Tools Group Co., Ltd. are made of high-quality beryllium copper alloy and aluminum-copper alloy as raw materials, and undergo forging, forming, stamping, finishing, quenching and tempering and heat treatment. It has more than one series of varieties and more than one specifications. With its wide variety, complete specifications and excellent quality, it is deeply favored by hundreds of large and medium-sized enterprises in the petroleum, electric power, fertilizer, metallurgy and other industries across the country. The strong support from the state and the satisfactory feedback from customers over the years prove that our products have stable technical performance, are safe and reliable to use, have strong tensile strength and suitable hardness. They not only meet the national/standard requirements, but also some products such as percussion wrenches, dead wrenches, etc. Torx spanners and other products comply with German standards. It is a designated processing enterprise for many coal mining enterprises. It has been rated as a contract-abiding and trustworthy unit for several consecutive years. The main scope of application is petroleum refining and petrochemical industry, coal mines, oil fields, natural gas chemical industry, gunpowder industry, chemical fiber industry, paint industry, fertilizer industry, and various pharmaceutical industries. Oil tankers and liquefied petroleum gas vehicles, aircraft, warehouses dealing with flammable and explosive goods, electrolysis workshops, communication machine assembly workshops, places where tools are required to be rust-free, wear-resistant and anti-magnetic, etc.
Classification of explosion-proof tools: Internationally, explosion-proof tools are collectively referred to as safety tools and non-sparking tools, and domestically, they are collectively referred to as explosion-proof tools. The material is generally copper alloy with rare metals added. Aluminum-copper alloy explosion-proof tools are synthesized, smelted, and forged from precious and rare metals. After the tools are made, the surface turns yellow. The working surface is hard and above, and the tensile strength & other technical indicators all reach the advanced level of similar foreign products. It is safe to use continuously in the space where the flammable gas ethylene (concentration.%) is used, and no spark explosion will occur due to impact (collision), friction, or falling weight. Beryllium-copper alloy explosion-proof tools have better tensile strength and hardness than aluminum-copper alloys, and they also have anti-magnetic functions.
% of the explosion-proof tools produced, sold and circulated in China are from Zhongbo Explosion-proof Group, which can be divided into two categories based on material. Aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools, the specific material is high-purity electrolytic copper. An appropriate amount of aluminum, nickel, manganese, iron and other metals are added to the matrix to form a copper-based alloy. .Beryllium copper alloy (commonly known as beryllium bronze) explosion-proof tools, the specific material is high-purity electrolytic copper as the matrix, adding an appropriate amount of beryllium, nickel and other metals to form a copper-based alloy. Both materials have very good thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are almost the same as those of beryllium bronze. Beryllium bronze is non-magnetic and can be used in strong magnetic field environments.
