pipe fittings manufacturer

 Different materials in the design of the beginning of the functional positioning, there is an accurate use, the effect is more obvious, the advantages are stronger and more professional. The application effect of brass joint products is very clear, and more valves of all-in-one machines are used in large pipeline conditions.
The door housing is fitted together and the installation is also very convenient. Among them, cemented carbide tubing joint products, high pressure resistance, and strong chemical stability, are many pipe fittings manufacturer consumers are very favorite product types. And in actual production practice.
Show a strong professional strength, there are also some plastic materials are also used in special fields.
Brass fittings are reinstalled repeatedly, and all ferrule fittings can be reinstalled multiple times, but the parts are damage-free and clean:
1. Insert the steel pipe into the joint body until the sleeve adheres to the cone in the joint body, and tighten the nut by hand.
2. Tighten the nut with a wrench until the tightening torque increases sharply, and then tighten it for 1/4 to 1/2 turns.
Inspection: Removable steel pipe Check that the assembly meets the requirements: there should be a uniform slight bump on the steel pipe at the end of the jacket. The sleeve cannot slide back and forth, but allows for slight rotation.
Tips for sub-installation reuse of brass fittings:
1. Saw down the seamless steel pipe of the appropriate length and clean the port burr. The end face of the steel pipe should be perpendicular to the axis, and the angular tolerance should not be greater tube fitting manufacturer than 0.5 degrees. If the steel pipe needs to be bent, the length of the straight line from the end of the steel pipe to the bending part cannot be less than three times the length of the nut.
2. Put the nut and sleeve on the seamless steel pipe. Pay attention to the orientation of the nut and sleeve, do not install it backwards.
3. Apply lubricating oil to the thread and jacket of the pre-assembled joint body, insert the steel pipe into the joint body, and tighten the nut by hand (the steel pipe should be inserted to the end).
4. Tighten the nut until the casing jams the steel pipe, and this turning point can be felt by the increase of the tightening torque (pressure point).
5. After reaching the pressure point, tighten the nut for 1/2 turn.
6. Remove the pre-assembled 14 tube fitting joint body, check the embedding of the edge of the sleeve, and the visible protrusions need to fill the space at the front of the sleeve. The sleeve can be rotated slightly, but not axially.
7, installation, the actual installation of the joint body thread coated with lubricating oil, compression nut and screw until the feelable tightening force increased, and then tighten 1/2 circle of installation.

ball valve manufacturer

 The tube fittings are reliable and safe to connect, convenient and fast construction, suitable for embedded installation, maintenance-free updates, and relatively superior economy.
The working principle of the clamping type pipe fittings is to insert the thin-walled stainless steel pipe into the bearing of the clamping pipe fittings, and use the special clamping tool to jam the stainless ball valve manufacturer steel pipe into the pipe fittings, and the cross-sectional shape of the clamping point is hexagonal, plus there is an O-ring seal between the stainless steel pipe and the pipe fittings, so that it has the characteristics of anti-leakage, anti-pulling, anti-vibration and high pressure resistance. Therefore, it is a relatively advanced connector in direct drinking water system, tap water system, heating system, steam system, industrial tubing system and industrial gas pipe system.
It is connected to water, oil, gas and other pipelines. Manufacturing standard: GB/T 19228.1 2003 Nominal pressure: ≤ 1.6MPa
Applicable temperature: -20°C ~110°C
Applicable medium: oil, water, gas and other non-corrosive or corrosive media
Manufacturing material: stainless steel 304 316L
Piping: stainless steel welded steel pipe of Φ15.88~Φ108 Stainless steel pipe fittings belong to a kind of pipe fittings, it is made of stainless steel materials so called stainless steel pipe fittings, it contains: stainless steel elbow, stainless steel tee, stainless steel four-way, stainless steel reducer, stainless steel pipe cap, etc., according to the connection method can be divided
There are four types of socketed stainless steel pipe fittings, threaded stainless steel pipe fittings, flanged stainless steel pipe fittings and welded stainless steel pipe fittings.
Stainless steel elbows are used where pipe fittings are turned; Flanges are used to connect pipes to pipes to each other, connected to the end of the pipe, and stainless steel tee pipes are used where the three pipes 14 needle valve converge; Stainless steel four-way pipe is used where the four pipes converge; stainless steel Reducers are used where two tubes of different pipe diameters are joined. Main stainless steel materials: 304, 304L, 316|, 316L.
Stainless steel pipe fittings are a general term for various stainless steel pipe connection workpieces, which can be divided into different categories according to shape, use, connection method, etc. It has the characteristics of easy installation, high performance and durability, and is widely used in various pipeline construction and installation.
Stainless steel tubes are still used in our lives is still more, in the production process of the product is the need to polish the operation, generally there are the following three forms of different polishing methods and their respective advantages and operation steps are related, so In order to pay attention to when choosing a polishing method, we 38 needle valve will briefly understand several different polishing methods of stainless steel pipes.
1, mechanical polishing: The advantage of this method is that the flatness of the product is better after processing, and the brightness is relatively high.
2, chemical polishing: its advantage is that the investment in processing equipment is relatively small, and the production efficiency is relatively high and the anti-corrosion performance is good.
3, electrochemical polishing: its advantages are that the mirror gloss remains long, the process is stable, less pollution, low cost, good corrosion resistance.

brass tube fitting

 Type stainless steel needle valve is whole process material 304316321201 stainless steel forging processing production of needle valve, brass is made by a brass alloy casting process of needle valve. Stainless steel material has corrosion resistance, resistance to high pressure, High temperature resistant, high cleanliness, a lot of advantages. The brass or copper materials do not have the advantages of resistance to high pressure, high temperature resistant, relative to the stainless 38 tube fitting steel needle valve as many, the scope of use type stainless steel needle valve is widely used.
Type stainless steel needle valve and instrumentation valve body and internal parts are all materials with solid or forging bar solid body directly, high density, tensile performance is strong, adopts CNC precision machining, precision degree is high, good seal. Brass type needle valve and yellow Brass instrument valve technology for forging casting body, low tensile performance, corrosion resistance and poor, not suitable for high temperature and high pressure, bad working conditions, such is only suitable for plumbing, air conditioning and other devices.
No load test method of the valve
Type a, test method, the needle valve test can be done under a pressure, the pressure corresponding to the trap of high working pressure, the pressure for saturated steam (238 degrees c) shall not be greater than 3.2 MPa. A load test, stress corresponding to the load 1% of the test pressure steam trap large displacement, but little is 5 kg/h.
Second, the test procedure, no-load test before the start of all valves closed, bucket is empty.
1, 2, 3, 1, open the valve, make the condensate excluding device and tested in trap test pressure Ps run under.
2, in the process of heating up, weighing and record the air quality of mt heat metering drum, record the Ps and steam pressure, steam temperature 0.
3 barrels of note to the hot measurement, plenty of water (about half a bucket), so that the test can normal operation in the duration of the actual needs.
The initial water temperature should be lower than the environment temperature 0 a least 01 8 degrees. Record the water temperature and the bucket of water quality of m1 01.
The daily maintenance of instrument type needle valve:
1, regularly check the oil level medium oil height, oil mist detector discretion to support him, on a regular basis to Chu water blocking device bottom dust accumulation of condensed water and impurities.
2, check the air pressure and adjust the flow of one-way throttle valve has enough opening and closing force, flexible motion;
3, check whether testing hole leakage or leakage, are leaking brass tube fitting air leakage need to replace the seal in time. High pressure water descaling injection valve not only stable high Xiao controllable operation, also should pay attention to the An run.
