Stainless steel tee

When it is necessary to divide the main flow in the pipeline for several streams used tees.

Stainless steel tee – this item conduit which serves as a connecting element and is used for routing, and also changes the direction of fluid flow. He, as the name implies has three holes, and that a third of them can be connected to a secondary “branch”, thereby dividing the stream.

Tees used on pipelines in the food, chemical industry, municipal services and other media industries. They are used to heat and vodomagistralyah in gas and oil pipelines.

Depending on the design of stainless tees share on: Transitional and ravnoprohodnye. That is, in the transition tee, elbow, which is perpendicular to the main flow has a smaller diameter, and all nozzles are ravnoprohodnom one diameter.

Ravnoprohodny – most commonly used in heating systems, and systems and cold water. Transition – has found its application in the chemical industry and in the oil and gas pipelines.

It is logical that for stainless steel pipes, tees also use stainless steel. In accordance with the requirements can be further insulated thermal insulation materials.

Stainless steel tee can be installed on the pipeline where fluid pressure does not exceed 16 MPa, and the temperature from -70° to +450°C. According to GOST 17376-01, the external diameter of the product should be in the range of 45 to 426mm.

Tees produce alloyed carbon steels of various grades, depending on where they are used. Steel grade should have a good resistance to high temperatures and corrosion. Place of use is calculated based on the internal and external influence on him.

Produce steel tees using the following methods:

• – Casting. Hot steel is poured into a special form;
• – Hot stamping;
• – Gas cutting parts, followed by welding;
• – Welding;
• – Gidroshtampovka;
• – Forging.

By way of manufacturing tees are: welded, seamless, chiseled, and Stamped.

Welded stainless tees made ​​of rolled tubes, cutting of her holes, and by welding it to the pipe.

Seamless tees produced using casting or forging, and then modify it already on the machine.

Although most of the manufactured tees manufactured to change the direction of flow at 90°, but also have the opportunity to order tees with angles of 30° and 60°.

Stamped (forged ) tees are made with stainless steel seamless pipe, and pictures for them is rolled sheet steel, which later be welded . Forged tees are produced in accordance with GOST 17376-2001 steel AISI 321 09G2C. Such products can withstand the load temperature of from -70 to +450°C, and pressures up to 16 MPa. The product is used in pipes for diverting a portion of the working environment to another element of the system .

Stamped tees produce standards TU -102-488-95. Their use at a temperature condition of -30 to +300°C, and at pressures up to 2.5 MPa.

By the method of mounting tees distinguished: welded, threaded and flanged.

Welded tees used in thermal communication pipelines and the installation of other systems that are subject to standards SNIP 3.05.05-84.

Stainless tees are very good when used in high humidity conditions, and have excellent resistance to corrosion.

Our company “Atomtehnology” LTD produces and offers to buy the tees that fully comply with the standards and are of high quality and reasonable price.
