    Description:

     

    Stud bolt, also known as the screw. Han Ming and Qing era furniture components name. GB Base standard corresponding to DIN975. Due to different locations and names are different. Generally refers to the setting member is connected between the legs of the lower surface of the frame. There corset waist furniture in the following parts of the main coupling member. Located in other parts of the general renamed teeth. In addition, also used in the construction, most decoration.ASTM A193 B7 B7M A320 L7 L7M Stud Bolt threaded rod are commonly used in offshore flatform, oil and gas. With PTFE coating, it is in high anti-corrosion.

    The specification for ASTM A193 covers alloy and stainless steel bolting for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, low temperature, or other special purpose applications. The ASTM A193 specification covers bars, bolts, screws, studs, stud bolts, and wire. The material may be further processed by centerless grinding or by cold drawing. Below are some of the ASTM A193 grades used commonly.

    Common ASTM A193 specifications:

    ASTM A193 B7 Alloy steel, AISI 4140 or 4142, quenched and tempered

    ASTM A193 B6 Stainless steel, AISI 410, heat treated

    ASTM A193 B8 Class 1 Stainless steel, AISI 304, carbide solution treated.

    ASTM A193 B8M Class 1 Stainless steel, AISI 316, carbide solution treated.

    ASTM A193 B8 Class 2 Stainless steel, AISI 304, carbide solution treated, strain hardened

    ASTM A193 B8M Class 2 Stainless steel, AISI 316, carbide solution treated, strain hardened

    ASTM A193 B8T Class 1 or 2 Stainless steel, AISI 321, with additional element of Titanium

    ASTM A193 B16 Chromium-Molybdenum-Vanadium, similar to B7 with Vandium added

    ASTM A193 B7M Similar properties as B7 but with specialized heat treating to create differing mechanical properties

    ASTM A193 B8R Stainless steel, AISI 209, also known as Nitronic 50, nitrogen strengthened

    ASTM A193 B8S Stainless Steel, AISI 218, also known as Nitronic 60, nirtrogen strengthened

    Application:
     
    Oil and Gas.

    Advantages:
     

    1, Not sticky: Almost all the material is not bonded with Teflon coating. Thin film also showed good adhesion properties.
    2, Heat resistance: Teflon coating has excellent heat resistance and low temperature properties. Short period of time can be high temperature to 300 ℃, generally between 240 ℃ ~ 260 ℃ can be used continuously, with significant thermal stability, it can work without embrittlement in freezing temperatures, it does not melt at high temperatures.
    3, Sliding: Teflon coating has a low coefficient of friction. Load sliding friction coefficient changes, but only in the values ​​between 0.05-0.15.
    4, anti-wet: Teflon coating surface water and oil production operations are not easy to dip solution, such as sticking a small amount of dirt, simply wipe clean. Downtime is short, save time and improve efficiency.
    5, Wear resistance: under high load, with excellent wear resistance. In a certain load, wear-resistant and non-adherence with the dual advantages.
    6, Corrosion resistance: Teflon is almost free from erosion of the drug, in addition to withstand molten alkali metal fluoride, a strong acid medium, and above all than 300 ℃ sodium hydroxide (including aqua regia), strong oxidizing agents, reducing agent and various organic solvents, can protect parts from being any kind of chemical corrosion.
