III.The Materials of Our Tools
1.Aluminum bronze (Al-bronze) HRC≥25°b>75-85kgf/mm2 Anti-explosion
2.Beryllium bronze(Be-bronze) HRC≥35°b>105-120kgf/mm2 Anti-explosion and anti-magnetic
3.45#steel The name of the national standard GB ,also called 1045 or 080M46 in JIS,C45 in DIN.
4.40 Cr
5Stainless Steel304
6 Titanium alloy
The non-sparking safety tools aluminum-copper alloys (aluminum bronze) and beryllium copper alloys (beryllium bronze), two materials.
Aluminum-copper alloy non-sparking tools is synthesized precious rare metals, smelting, forging made the tool surface yellow. Stretch of more than HRC25 ° tensile strength δ b> 75-85kgf/mm2 other technical indicators all reached the advanced level of similar foreign products. Are to ensure safe continuous use space in the flammable gas ethylene (concentration 7.8%), red (hit) strike, friction drop hammer produces no sparks explosion.
Beryllium copper alloy non-sparking tool is synthesized with military materials and precious rare metals smelting, forging made the tool surface yellow. Stretch of more than HRC35 ° tensile strength δ b> 105-120kgf/mm2 other technical indicators all reached the advanced level of similar foreign products. Continuous use in flammable gas hydrogen (21% concentration) space are to ensure safety, red (hit) strike, friction drop hammer produces no sparks explosion. Beryllium copper alloy explosion-proof tools also have special antimagnetic function, the normal use of the magnetic field environment.
IV.Surface Treatment
The surface treatment non-sparking tools:
against electrostatic spray chart, true color
The surface treatment of the special tools:
flange processing (also known as boiled black), electricity Ming paint, galvanized chrome-plated
V.Manufacturing Process
Process of non-sparking tools:Foundry (ingredients - melting - coke casting - cut outlet - into semi-finished library) machining (drilling - garland, flower arrangement - flat chamfer - fitter throwing neck - marking - polished - heat treatment - into finished products)Process of special tools:Forging blank - into finished products - processing (drilling - flower arrangement, garland, red flowers - flat chamfer - gas cutting rough - hit the the tail hole - grinding wheel polish - surface treatment - into finished products
VI."Non-sparking" Tools’Application
"Non-sparking", "spark reduced", "spark-resistant" or "spark-proof" tools are names given to tools made of metals such as brass, bronze, Monel metal (copper-nickel alloy), copper-aluminum alloys (aluminum bronze), or copper-beryllium alloys (beryllium bronze).
Commonly used hand tools are often manufactured of steel alloys. Preferred "non-sparking" metals have less tensile strength than steels usually used to make tools. A lower tensile strength means the metal has less strength or resistance to tearing apart when stretched under test conditions. It also means that these tools are softer, wear down more quickly than ordinary steel tools, and have to be dressed more frequently.
Non-sparking safety tools mainly applicable scope is:
Petroleum refining and petrochemical industry, coal, oil, natural gas chemical industry, powder industry, chemical fiber industry, paint industry, fertilizer industry, all kinds of pharmaceutical industry. Oil wheel and liquefied petroleum gas (LPG) vehicles, aircraft, management of inflammable and explosive goods warehouse, electrolytic workshop, assembly workshop, communication machine realization for tools are not rust, wear-resisting antimagnetic, etc.
In the normal process of using aluminum-copper alloys are more applicable to conditions of pressure equipment and explosion-proof environments with less stringent requirements (such as gas stations, small oil depots, etc.). The beryllium copper alloy explosion-proof tool for refineries to switch gas stations, gas production plants, drilling crew and so on.
