Carbon Steel Tee ANSI/ASME/GOST/JIS/DIN/EN Carbon Steel Tee butt weld seamless pipe fittings

Carbon steel tee is also a kind of pipe fitting, usually have equal diameter tee and different diameter tee. Carbon steel can be divided into 10# 20# A3 20g 20g 20g 16Mn ASTM A234 ASTM A403 etc. All are made of different materials, the production process has the push, the suppression, forging, casting and so on. The output of different specifications and models can be produced according to different scales to ensure that the output is adjusted to the carbon steel tee of different industries and positions. Its characteristics: corrosion resistance, acid and alkali resistance, surface smooth, acid and alkali resistant high temperature resistant, reasonable prices, good appearance, texture performance is strong, long service life, etc., widely used in petroleum, chemical industry, nuclear power station, food manufacturing, construction, shipbuilding, papermaking, medical yao etc, in different industries have different use, show the use value in the industry.

The corrosion resistance of carbon steel tee is due to chromium, but because chromium is one of the components of steel, the protection method is different. This tightly adhering rich chromium oxide protects the surface to prevent further oxidation. This layer of oxide is extremely thin, and through it can see the natural sheen of carbon steel tee, making carbon steel tee has a unique surface.

In order to prolong the life of the triton tap and improve the quality of thread processing, it is necessary to pay attention to the precautions when processing and production.

Choose a good silk cone material. Adding special alloy element to ordinary high speed tool steel can improve the wear resistance and toughness of the tap. Appropriately increase the back of the tap. However, it should be noted that if the back of the back is too large, it is easy to get the cuttings into the corner of the tap after the cutting, and the thread of the tapping is not good. It can significantly improve the wear resistance, heat resistance and lubricity of the tap. All carbon steel tee elements have a common characteristic, namely chromium content is above 10.5%. Choose the tool heat treatment method rationally, to take into account the hardness and toughness of the tap. Increase the Angle of the tap properly. However, it should be noted that, if the front Angle of the tap is too large, it can easily lead to the multi-edge of the tap and the tapping of the tap.

Notes for the purchase of carbon steel:

(1) first determine whether the controlled medium is oil or water.

(2) calculate the flow rate of the controlled medium m3/ h.

(3) select the three-pass tempering valve diameter according to the controlled medium and its design flow.

(4) according to the valve body material (casting copper or iron T), the connection form (F pipe thread, flange, G mid-december, taper pipe threads), valve structure slide valve type rotary valve type, H (Z), temperature control range and installation type determine the 3-way regulating valve type.

(5) according to the different flow direction of the three valve ports, the three-pass regulating valve can be used for confluence or shunt control.

(6) a three-way thermostat can replace a two-pass valve and a three-way takeover.

(7) to prevent impurities in the medium from dead or blocked, the three-way tempering valve should set up the filter before the valve.

(8) the three-way temperature regulating valve may be installed in any position, but the emergency manual device should be installed in a convenient position.

(9) rotary valve type three-way temperature control valve has six types of installation, which are suitable for the connection of any pipe. The installation type is selected according to the actual pipeline connection of the system.

(10) and streaming tee is the role of tempering valve two different temperature of the fluid through valves before blending temperature between the third between the two kinds of temperature of fluid, the valve has two imports (B for the entrance, C has A low temperature entrance) and export (A), A temperature sensing element installed in the outlet of (A). Shunt type tee the tempering valve is A kind of flow through valve in proportion into two after the road, when the valve in the closed an export at the same time will open another export, this valve has an entrance (A) and two export (B to bypass backflow mouth, C for shunt cooling).

There are many kinds of tee, and there are some ways to choose the three links. These methods are also selected according to different environment.
