Fire Safe Testing of Ball Valve and Gate Valve These tests determine the resistance of fire-safe- Ball Valve and Gate Valve to a burn under controlled conditions as defined in common industry standards like: API 607,API6 FA.
High pressure globe valve with electric actuator High pressure globe valve, 3inch 2500LB, pressure seal bonnet, the connection is BW.Its material is WCB, suitable for water, gas, oil.The way it operates is electric actuator with handwheel. High-pressure shut-off valve has the following advantages:
Pneumatic Ball Valve Pneumatic ball valve is a kind of valve which is equipped with pneumatic actuator. The execution speed of pneumatic actuator is relatively fast, the fastest switching speed is 0.05 second/time, so it is also called pneumatic fast cut off ball valve. Pneumatic ball valves are usually equipped with a variety of accessories, such as solenoid valve, F.R.L, limit switch, locator, control box, etc. The advantages of pneumatic ball valve in the pipeline are on the below:
Gate valve means stem nut on the bonnet or bracket, the opening and closing of the brake plate is to use rotary stem nut to achieve the valve stem lifting. This structure is advantageous to the lubrication of the stem, and the opening and closing degree is obvious, so it is widely used. Usually on the lifting rod with trapezoidal screw threads, through the valve top of the nut and the guides lot on the rotating movement into a straight-line ,that is, the operation torque into operation Thrust.
EDELON VALVE CO., LTD is a well-known manufacture,we have advanced equipment to support production.When it comes to production,it is necessary to discuss about ways of connection. We have various types connections such as flange ,butt welding,socket welding and so on. Today,I 'd like to introduce butt welding.
DYE penetrant inspection (DPI), also called liquid penetrant inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.
This butterfly valve is suitable for harsh working environment of strong erosion. The specification is as below. Connection Type: Flange Body：Super duplex 5A Disc：Super duplex 5A Stem ：2507 Pin ：2507 With position indicator
Positive Material Identification (PMI) is the analysis of a metallic alloy to establish composition by reading the percentage quantities of its constituent elements. The object of this nondestructive testing method is to identify metal alloys in place using a portable X-Ray fluorescent analyzer that determines the elemental composition of the material. At Sedelon, we have our own hand held Positive Material Analyser for confirming all stainless steel grades, Inconels, Hastelloys, Duplexes Steels and much more, without having to transport, alter, or damage the material. For Duplex Stainless Steel and Stainless Steel valves, PMI is conducted by using PMI XRF portable test gun, pointed at the external surface of completed valves. Parts of valves to be PMI tested are: a)Body, b)Bonnet, c)Stem, (for all valves having externally-exposed stems) By using PMI test, we can confirm all material received against orders raised by clients, and all tests can be witnessed by clients or their nominated inspectors.
Sedelon Valve Provide a lot of Check Valves.Such as Swing Check Valves,Lift Check Valves,Wafer or Dual Palte Check Valves,Tilting Disc Check Valve and so on. Today we specially recommend the High Pressure Seal Tilting Disc Check Valve. The High Pressure Seal Tilting Disc Check Valves’ Main Feature: 1.Design of double eccentric disc,When valves closed, the valve seat and the sealing surface gradually touch, in order to achieve no impact, no noise. 2.The design of High Pressure Seal and Micro elastic metal seat can make good sealing performance. 3.Small flow resistance and save energy 4.Butterfly valve design, quick, sensitive switch, long service life. Tilting Disc Check valve generally applies to clean medium, should not be used for medium containing solid particles and viscosity is bigger. As a one of main products in Sedelon Valve Company,The main production material of Tilting disc Check Valves is Cast steel, Stainless steel and Alloy steel ,Bronze,Cast Iron and so on.
Penetrant Testing（PT） By applying penetrant, the redundant parts is removed with a detergent, and if necessary, applying imaging agent to obtain an indication of some defects opening on the surface in the part. Penetration testing is based on the liquid to the solid's wetting ability and capillary phenomenon in the physics, first let contain dyes and high penetration of the liquid penetrant, coated to the surface of the tested workpiece, due to the liquid's wetting action and capillary action, the penetrant infiltration into the surface opening defects. After applying the penetrant, it is permitted to sit on the surface for a specified period of time (the "penetrant dwell time"), then the part is carefully cleaned to remove excess penetrant from the surface. A light coating of developer is then be applied to the surface and given time ("developer dwell time") to allow the penetrant from any voids or fissures to seep up into the developer, creating a visible indication.
Sedelon ®---------Bronze Valves Expert Zhejiang Sedelon valve co., LTD is a professional bronze valves company production factory, we are the best bronze valves manufacturer in China. The material of Bronze has characteristics of low melting point, high hardness, plasticity, and wear resistant, corrosion resistance. So bronze valves have excellent impact resistance strength,minimum heat loss and corrosion resistance. Bronze valves are generally used in the chemical and Oil field and mainly for the offshore, platform and marine usage. Sedelon produces the bronze valves mainly according to the API 600 Standard.It’s not easy to produce and process the bronze valves. We should pay much attention especially in the casting process---This is the beginning part and the vital part. Flange end Dimension :ANSI B16.5 Butt Welded Dimensions：ANSI B16.25 Design and Manufacture：API 600 Pressure Test：API 598 Main material： C95800、C95500、C95200、C95300、C95600、C61900、C63200, ect. *The valves’ flanges are under the processing . According to the client’s requirements, the flanges finish can be processed as Raised face or Flat face or RTJ type.
Duplex 2507(5A) is a widely used variant of stainless steel (both Ferritic and Austenitic). Duplex 2507(5A) exhibits excellent corrosion resistance. It resists intergranular and crevice corrosion. It also shows appreciable resistance to pitting. Chloride stress corrosion cracking is also dealt with easily using Duplex 2507(5A), at a temperature of 150 degree Celsius. It proves to be an excellent substitute of austenitic grades in marine environments. It shows good thermal resistance up to a range of 300 degree Celsius. It can be easily welded by most of the standard methods, the only compulsion being the use of filler metals. The machinability is low on account of its high strength. This variant of steel has a wide variety of applications. It is used in oil and gas exploration, chemical processing industries also make use of this alloy. Most of the processing equipment utilizes Duplex 2507(5A). It is also used by storage and transportation units of industries. Pulp and paper digesters, liquor tanks and paper machines also use Duplex 2507(5A). It is highly suitable for usage in marine environments. Super Duplex Stainless Steel 2507 Ball Valves are internationally accepted by companies around the world. They are highly welcomed by clients from UK, Turkey, Germany, Australia & USA. Mechanical properties of Duplex Stainless Steel 2205(4A) Ball Valves, Super Duplex Stainless Steel 2507(5A) Ball Valves.
