How to use explosion-proof tools correctly

First, when using tools, they should reasonably select their varieties and specifications according to their needs, and they should not be used as small on behalf of large ones, let alone as steel tools. It should be pointed out that in the use of live wrenches, pipe pliers, wrench, should pay attention to the direction of force requirements, not arbitrary twist, in the use of edged tools, first of all should determine the hardness of the workpiece itself, when its hardness is higher than the hardness of the tool should be prohibited. When the workpiece is fixed by motor tightening, semi-permanent or corroded, and no other measures are taken before using hand tools, it should be prohibited to use, so as not to damage the tool. Second. After the explosion-proof tools are stopped, they should be wiped clean at any time. half

In 2019, the company once again passed the audit of the national standard-setting unit for explosion-proof tools.

In 2019, the company once again passed the qualification audit of the national standard-setting unit for explosion-proof tools. Since the company participated in the drafting of national explosion-proof tool standards in 2002, it has drafted dozens of national explosion-proof tool standards.

Company research and development of new products explosion-proof seamless container with successful listing!

The company's technology research and development center, held a new project acceptance work meeting, research and development of new products explosion-proof seamless containers through acceptance, officially listed. Explosion-proof containers are widely used in flammable and explosive places with the explosion-proof characteristics of no spark and no detonation. The material for making explosion-proof containers is explosion-proof copper alloy. The original production process is to cut the plate into the corresponding shape and weld it. Such as explosion-proof bucket, fire bucket, etc. However, these process products have many problems and disadvantages: such as irregular appearance. Cutting, forming, crimping, welding, all hand-made, can not guarantee the appearance of normative, consistency. Second, the strictness is bad. Handmade

Introduction of mechanical properties of explosion-proof tools

Explosion-proof tools internationally known as non-sparking safety tools, mostly divided into beryllium bronze and aluminum bronze two categories: ① advanced developed countries highly recognized beryllium bronze explosion-proof tools, such as Europe and the United States, Japan, South Korea, Singapore, Australia and so on. It is a combination of military materials and precious rare metals. The tool is golden in color, with HRC30-40 hardness, tensile strength: 1117-1326N/mm2, elastic limit: 840-880N/mm2, elongation δ<1.0, resistance 8-6, thermal expansion coefficient: 0.000012, density: 8.60g/cm2, magnetic field strength: H0, also known as explosion-proof antimagnetic tool

Origin of domestic explosion-proof tools

As early as 35 years ago, in China's petroleum, chemical, oil refining, oil and gas transportation and other flammable and explosive places, accidents of detonating explosive gases caused by tool friction and impact occurred from time to time, resulting in serious losses of national property and personal safety. There is no guarantee. In order to ensure personal safety and national property from loss, we had to import explosion-proof tools with very expensive foreign exchange (at that time, the price of foreign explosion-proof tools was 4.5 times that of our present). In 1983, at the beginning of reform and opening up, the petrochemical industry rose. Yang Qinglai, senior engineer and chairman of the board, and his R & D team, after careful market research, evaluation, investigation and trial production, decided to develop Chinese explosion-proof tools according to the Japanese JIS explosion-proof tool standard according to the experience of manufacturing mechanical tools of the predecessor. After six years of hard work and thousands of tests, explosion-proof tools that meet the national standards were produced in 1989, filling the national gap. The company was qualified for national import and export in 1996, and the domestic explosion-proof tools went abroad from import to export explosion-proof tools.
