Ball Valve is closed parts is a ball, the ball around the center line of the body to achieve the opening and closing of a valve.

Applicable place
Is mainly used for nominal pressure 16~140 PN, nominal size 8~50 DN low pressure, small diameter pipe, used to cut off the flow and change the flow of water distribution or for the need to quickly open and close the place.

main features
1) small flow resistance;
2) simple structure;
3) small in size and light in weight;
4) at present, the sealing surface material of the ball valve is made of plastic, and the sealing property is good;
5) easy to operate, open and close quickly, easy to control the distance;
6) maintenance is convenient, the sealing ring is generally active, easy to remove and replace;
7) fully open or fully closed, the ball and valve seat sealing surface and the dielectric isolation, the media through the valve sealing surface will not cause erosion

Note editor
1) installation position, height, import and export direction must be in line with the design requirements, thread connection should be firmly close.
2) all kinds of manual valves installed on the insulation pipe, the handle shall not be down.
3) the valve must be installed prior to visual inspection, the valve plate should be consistent with current national standard "universal valve logo" GB 12220. For the work pressure is greater than 1 MPa and in the main pipe to play the role of cut off valve, the installation should be carried out before the strength and sealing test, after passing the convenient use. Strength test, the test pressure for the nominal pressure of 1.5 times the duration of not less than 5min, the valve housing, packing should be no leakage for qualified. Seal test, the test pressure is 1.1 times the nominal pressure; test pressure test duration should meet the requirements of JB/T 9092 standard, with no leakage in the valve sealing surface as qualified.
4) the valve flange and pipe flange between the pipeline design requirements for the installation of sealing gasket.
5) with the transmission mechanism of the ball valve, according to the provisions of the provisions of the use of product installation.

Laser Cladding Powder

Nickel Based Laser Cladding Powder

Ni base alloy powder is mainly made of NiCrBSi or NiBSi. Ni-based self-fluxing powder has good wettability, corrosion resistance and high temperature self-lubricating effect, and is used in components with heat resistance, corrosion resistance and thermal fatigue resistance. In general Ni35,Ni45,Ni60 etc can be used for laser cladding, the No means hardness of powder. Inconel 625 and 718 has good corrosion property under higher temperature, also widely used for laser cladding process.


Cobalt based Laser Cladding Powder

Cobalt-based alloy powder is the cemented carbide resistant to various types of wear and corrosion as well as high temperature oxidation. That is, the so-called cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy cobalt-based alloy is mainly composed of cobalt, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, Alloying elements such as lanthanum, and occasionally a class of alloys containing iron.

Co-based self-fluxing alloys have good high temperature performance and wear resistance and corrosion resistance, and are used in petrochemical power, metallurgy and other industrial fields where they are wear-resistant, corrosion-resistant and high-temperature resistant.

Laser Cladding


Iron based Laser Cladding Powder

The work pieces required for laser cladding and manufacturing in the actual industry are mainly carbon steel and cast steel. The Fe-based alloy is close to the base material in composition and has good wettability. The advantage of Fe base powder is lower cost and good wear resistant of cladding layer. As a result, it`s the most widely used for laser cladding process. It is suitable for parts that require local wear resistance and are easily deformed.

Laser Cladding Work Part



WC blended Laser Cladding Powder

Tungsten carbide blended with Ni alloy powder is the best choice for wear resistant work piece. This unique process can bring excellent wear, corrosion and high temperature resistant. Our blend powder can achieve different portion of WC from 35% to 60% without crack under suitable cladding parameter.
