A hexagonal drill rod, as the name suggests, features a hexagonal cross-section rather than the conventional circular one found in standard drill rods. This design alteration is not merely aesthetic; it serves a functional purpose that significantly enhances performance. The hexagonal configuration provides greater surface area, which in turn increases the contact area between the rod and the drilling machine. This results in better torque transfer, reducing slippage and enhancing overall drilling stability.

The primary advantage of glass fiber tanks lies in their corrosion resistance. Unlike traditional metal tanks, they do not rust or corrode when exposed to aggressive chemicals, acids, alkalis, or extreme temperatures. This characteristic makes them ideal for storing hazardous liquids in the chemical, pharmaceutical, and petrochemical industries. They are also widely used in water treatment plants, where they can withstand prolonged exposure to chlorine and other disinfectants.

In conclusion, the rock drill shank adapter is an indispensable tool in the world of underground construction. Its ability to connect various drilling tools to the drill rig, accommodate different sizes and types of drill bits, and ensure durability and safety make it an essential component for any contractor working in this field. By investing in high-quality adapters, contractors can improve efficiency, reduce downtime, and create a safer work environment for their employees.

  • Maintenance and Replacement


  • The designation 5 8 might initially seem cryptic, but it refers to specific measurements and material characteristics that are engineered to meet particular performance requirements in hydraulic systems. Typically, hydraulic hoses are encoded in a manner that informs the user about their inner diameter, working pressure, and spiral wire reinforcement.


  • Since hose may change in length from +2% to -4% under the surge of high pressure, provide sufficient slack for expansion and contraction.
    Never use a bending radius less than the minimum shown in the hose specification tables. The bending radius of the hose should be far away from the hose fitting (A>1.5R)
    Hose bending radius is bigger when it is in motion.
    Choose proper fittings, avoid twisting in hose lines bent in two planes.
    Avoid twisting in hose by use clamp properly.
    Hose should not be twisted, hose is weak when installed in twisted position. Also pressure in twisted hose tends to loosen fitting connections. Design so that machine motion produces bending rather that twisting.
    Leave proper length when the hose in connected
    Choose proper fittings, avoid too small bending radius and excess force.
    Choose proper fittings, avoid excessive hose length.
    Reuse friction, avoid hose touching the object directly or far away from the object.
    Hose Active Working Pressure Working Life
    As shown , when active working pressure in 1.25 times recommended working pressure, the hose working life is only half of i under working in recommended working pressure.
    Store Conditions of the Assembly.
    1.If possible, the storing temperature range is within 0-30 ℃. During storing, temperature should not exceed 50℃
    2.The storing areas can not place equipment within can produce ozone.For example mercury vapour lamp, high voltage electric device and other equipment which can produce spark or set out electricity.
    3.Can not be placed with erosive products or exposed over gas-volatile on these products.
    4.Far away from heat source and equipment which can produce electric field or magnetic field
    5.Avoid sunshine or strong artificial light source
    6.Avoid to touch the sharp objects or the ground
    7.Guarantee against rodent attacking.
    8.Observe the rule of “First in, then first out”

  • The automotive industry also benefits from hydraulic hose hand crimpers. They are used to create and repair hoses for brake systems, power steering, and transmissions. The ability to work with hydraulic hoses directly contributes to vehicle safety and reliability, making it imperative for mechanics to have access to quality hand crimpers.


  • 1. Pressure Handling A 4% hydraulic hose can often be designed to handle higher operating pressures compared to a 3% hose, which is essential for demanding applications in industries like construction, manufacturing, and oil and gas extraction. Higher pressure capability reduces the risk of hose failure, enhancing system safety.
