38 tube fitting

Pipe connector of cutting sleeve type has a secure connection, compression ability, high temperature resistance, impermeability, and repeatability, easy installation and maintenance, etc. As petroleum, chemical, natural gas, oil refining, etc., the rapid development of the industry, the quality of product requirements, card sets of joints play a critical role, greatly improving the sealing performance of the product.
By joint pipe connector of cutting sleeve type has the body, card sets, the nut, the three parts. When the card set and nut set, on the steel tube inserted into the connector body, screw nut, card sets of front lateral, joint joint 38 tube fitting cone body, seamless steel pipe, bitten by the blade evenly into, therefore to form effective seal. Card sets of joint is oil refining, chemical, oil, natural gas, food, pharmaceutical, instruments and meters, etc., pipe line of automatic control device, a more advanced fittings.
Pipe connector of cutting sleeve type has the impact on the industry's role is very big, also has been widely promotion and application.
Brass type needle valve and instrument varieties such as ball valves also is less, because of pressure on the sex is not enough, so are generally low class product. In respect of structure, the stainless steel needle valve body etc are larger and brass pin type valve, because the stainless steel needle valve type generally use temperature is higher, the pressure is high, so in the central stuffing box design that is done is higher, in case of leakage with the rising of middle pressure and temperature.
And brass type needle valve structure is simple, do not need to do is too high, of central working conditions for the use of pressure and temperature are relatively low. Type of valve and brass and stainless steel needle valve type of production cost is large, so the price of the stainless steel needle valve type is relatively higher, and the brass type needle valve price is relatively cheap.
Type carbon steel needle valve is the instrument measuring pipeline system is an important part of the carbon steel valves with easy installation and disassembly, connecting fastening, to fire, explosion, and brass tube fitting the advantages of high compression capacity, sealed performance is good, is power stations, oil refining chemical type carbon steel needle valve sealing when installation should make the flow of medium and the direction of arrow on valve body.
Type carbon steel needle valve structure is designed on the basis of, is now the most common application of a new generation of the valve. First body corrosion, mainly is the right to choose material. Although the anticorrosion material is very rich, but can choose well, or not easy thing, because the problem of corrosion is very complex. Choose the difficulty of the body material, also is not only considered the corrosion problem, at the same time must consider pressure and heat-resistant ability, economically reasonable, buy whether factors such as easily.
