Elbows Stainless Steel

The company “Atomtehnology” makes elbow stainless steel AISI 321. Preferably they are used for pipelines or pipe systems, where it is necessary to change the direction of fluid flow. You can also use decorative metal to change the position of the specific elements for structures in space.

Seamless steel pipe bends and stainless AISI 321 – is the most common fittings for pipelines. They are manufactured according to GOST 17375-03 and GOST 30732-2006. In compliance with the specifications elbows should own individual characteristics such as:

a) normal angle may be 180 °, 90 °, 60 °, and 45 °;

b) objections to withstand temperatures from -70 ° C to +450 ° C;

c) the outer diameter (D) 32mm ÷ 1,220 mm

d) nominal pressure (PN) – about 16 MPa.

The main objections are made from steel grades : AISI 321, AISI 301 AISI 410, AISI 410S.

Seamless stainless steel pipe bends and directly used in the construction of pipelines, because they are molded part, the purpose of which is to be able to change the direction of the pipeline. Withdrawal can be bent up to 90 °, but even with the removal of the bending angle of 45 ° is considered steeply curved. Taps Stainless very necessary in order to be able to change the direction of rotation of the fluid in the lines (pipe located at different angles and which is connected to the taps by the ” joint to joint “). Steel and stainless steel elbows are used extensively in order to make the installation of pipelines in certain private houses or buildings of any type.

Seamless Stainless steel elbow have significant reliability and durability. Therefore, in an hostile environment it is difficult to find a better version of the pipeline system than the elbows of stainless steel AISI 321. Elbows are manufactured by a variety of different materials technology that enables to use them in a wide range. Matter what material was used for the manufacture of taps, and on the basis of its characteristics, the data taps can be applied to the construction of pipelines designed to work : with intense temperature changes, high load, or with significant humidity.

Seamless elbows AISI 321 have such excellent qualities such as elasticity, hardness, ductility, corrosion resistance and good weldability, and they are resistant to changes in temperature, eco-friendly. These qualities allow you to create the design of the pipes that are not only durable and reliable, but also safe for human health. That’s why such pipelines are increasingly used in the food, chemical and energy industries, engineering, public utilities (water and steam heating or just water). Thus, as a rule, this construction is made of elements made ​​preferably of the same material, in this case stainless steel mark AISI 321.

Bends are made in several ways: forged, hot-formed and cold-formed, stamped and welded sectional. Under the surface of the stainless type, distinguish taps with mirror or matte finish. A distinction between: welded and seamless. Mostly, taps are made casting or welding process. Basically, in the pipeline at the most important area of ​​use Elbows steel seamless. Why is seamless, not foundries? Because the cast taps have a maximum internal diameter of 200 mm, and in the production of seamless steel needed outlet with a diameter of about 1208mm even. In order to reliably connect to the pipe bends used a special thread. Taps steel, stainless steel may have an internal thread at both ends or at one end an internal thread, and at the other end – the exterior. And the inner and the outer diameter of the steel drain is at the output and the input. In addition to completely coincide with the diameter of the pipe to which they are attached. In most cases, make the weld joining method that itself provides a significant strength of this design.

As a result, we can say that bends steel, stainless AISI 321, can be made of various sizes and shapes. A significant indicator of the reliability of taps offered by our company is confirmed by an appropriate certificate. So if you want to buy high quality seamless pipe bends, please contact us!
