Cangzhou new realm to talk about explosion-proof live wrench price assault market key. Wrenches are basically divided into two types, dead wrenches and live wrenches, the former refers to the wrench that has a fixed number written on it, and the latter is a movable wrench.
1. Dull wrench: one or both ends are made with fixed-size openings to twist nuts or bolts of a certain size.
2. Plum wrench: The working end with hexagonal hole or twelve corner hole at both ends is suitable for occasions where the working space is narrow and ordinary wrenches cannot be used.
3. Dual-purpose wrench: one end is the same as the single-ended wrench, the other end is the same as the plum wrench, and the bolts or nuts of the same specification are twisted at both ends.
4. Live wrench: the opening width can be adjusted within a certain size range, and bolts or nuts of different specifications can be twisted. The structure of this wrench is characterized by fixed jaws made into flat jaws with fine teeth; One end of the movable jaws is made into flat jaws; The other end is made into concave jaws with fine teeth; Press down on the worm, the movable jaws can be quickly removed, and the jaw position can be changed.
5. Hook wrench: also known as crescent wrench, used to twist flat nuts with limited thickness, etc.
6. Socket wrench: It is composed of multiple sockets with hexagonal holes or twelve corners and equipped with handles, adapters and other accessories, especially suitable for twisting bolts or nuts with very narrow or deep depressions.
7. Allen wrench: L-shaped hexagonal wrench, dedicated to unscrewing Allen screws. The model of the Allen wrench is according to the size of the opposite side of the hexagon, and the size of the bolt has a national standard.
8. Torque wrench: it can show the applied torque when twisting the bolt or nut; Or when the applied torque reaches the specified value, a light or acoustic signal is emitted. Torque wrenches are suitable for installations where the amount of torque is clearly defined.
The explosion-proof live wrench is 6″-24″ and the product is calendered by a large friction press. High strength, stable mechanical properties and long service life. The stressed part does not bend, deform, or crack. , bridge brand explosion-proof tools national recommended brand, please the majority of users to look for trademarks, beware of counterfeiting. Explosion-proof performance up to class IIC. Suitable for hydrogen concentration of 21% in the environment without sparks, no detonation gas. Our company registered capital of 50 million, covers an area of 66,000 square meters, is a state-recognized high-tech enterprise, the state decentralized self-operated import and export enterprises, China explosion-proof tools national standard drafting unit, professional manufacturing of explosion-proof tools and special tools, percussion tools fully comply with the German standards DIN7444, DIN133.
Material: aluminum-copper alloy, beryllium-copper alloy
Size: 100mm(4″), 150mm(6″), 200mm(8″), 250mm(10″), 300mm(12″), 375mm(15″), 450mm(18″), 600mm(24″)
Product characteristics: explosion-proof tools are divided into two types, one is beryllium bronze tools, which are national II.C grade products, and do not detonate gas when operating in hydrogen with a concentration of 21%; The other is aluminum bronze tools, which are national II.B products, and do not detonate gas when operating in ethylene gas with a concentration of 7.8%. Working principle: explosion-proof wrench and mechanical friction or impact, the heat generated in a short time is absorbed and conducted, because the copper itself is relatively soft, friction and impact have good concessions, not easy to produce tiny metal particles, so we can hardly see the spark. Therefore, explosion-proof pipe clamps are suitable for operation in various explosive, flammable, strong magnetic and corrosive environments, without sparking and detonating gases. Scope of use: widely used in petroleum, chemical, mining, coal mine, gas production, metallurgy, aviation, storage and transportation, pharmaceutical, gas production, plastics, leather, pyrotechnics, firecrackers and other industries.
Features of the use of the movable wrench:
1. The live wrench can adjust the size of its own opening within a certain size range;
2. The movable wrench is an explosion-proof tool that can twist bolts or nuts of different specifications and models;
3. The screws within the range can be done with a movable wrench.
Material of explosion-proof live wrench: aluminum bronze alloy and beryllium bronze alloy as raw materials.
The use of movable wrench: Because the two alloy raw materials used do not spark when they hit metal machinery or friction, they are suitable for explosive, flammable, strong magnetic and corrosive occasions.
The characteristics of the movable wrench: it has high strength, long life, stable mechanical properties, and its stressed parts do not bend, deform or crack.
The explosion-proof live wrenches produced by our factory have a complete variety and many specifications, which are widely used in petroleum refining and petrochemical industry, coal mine, oil field, natural gas chemical industry, gunpowder industry, chemical fiber industry, paint industry, fertilizer industry, various pharmaceutical industries, petroleum wheels and liquefied petroleum gas vehicles, aircraft, warehouses operating flammable and explosive products, electrolysis workshops, communication machine assembly workshops, places requiring tools not to rust, wear resistance and anti-magnetism, petroleum, chemical, oil refining, petrochemical, power generation, shipbuilding, metallurgy, mechanical processing and other industries maintenance and maintenance work.
