Stainless pipe

Seamless pipe

«Thundering fire blazing brilliance of steel!» — sung in the famous song. It is from seamless steel pipes produced weapons. Such pipes are its length of joints or welds. Are produced by rolling, forging, pressing or drawing. They are in demand in virtually all industries. The most popular brand is considered seamless pipe 12X18H10T. What is the main flaw of the weld? As if quality was not performed welding, it is impossible to exclude breaking of the seam. But if the pipes circulate the dangerous chemical liquid, the possible leakage should be excluded.

Dignity

Reliability, durability, aesthetics and versatility, excellent protective and anticorrosive properties. Such a tube — an absolute guarantee of unwanted leakage of aggressive media in industrial plants, or water from a household communication is the key to good consumer properties of constructed objects. The use of stainless thick-walled and thin-walled tubes allows you to vary the weight and metal consumption of the structure. Thin-walled pipe gives the design a lightness, it is widely claimed, for example, designers.

Disadvantages

The relative disadvantage of such pipes is their high cost. But given the reliability and durability, this price is more than justified.

The use of different brands of stainless steel tubes

Brand 06HN28MDT in demand for chemical equipment operating in the acid — boiling H2 SO4, etc. acids (except 55% Н3РО4 and acetic acids). Can long be used in petrochemical production and columns synthesis.

10X17H13M2T

Resistant to acids pipe 10X17H13M2T for austenitic grades alloyed with chromium, Nickel, molybdenum and titanium. The consumption of this alloy is close to 70% of all manufactured stainless steel. The optimal doping improves performance. Nickel increases the ductility and corrosion resistance, chromium and molybdenum increase the heat resistance and corrosion resistance, titanium increases due to the specific strength under load. These pipes are easy to weld without pre-treatment and final heat treatment of the weld. They are widely used for food, medicine, chemical industry, petrochemical industry, metallurgy, shipbuilding — in the most difficult conditions. Advantages of such pipes are stored for a long time at a temperature of ≤ 600C. Thanks to its longevity, significantly reduced repair costs and equipment maintenance.

10Х23Н18

Heat-resistant austenitic steel 10Х23Н18 of hard alloy steel is the basis of details of combustion chambers, steam generators and boilers, fragments of heat-exchanging fittings, working at t° to 1100 °C.

12KH18N10T

The same steel pipe 12X18H10T is now considered one of the most popular in the sector of metal. It is composed of chromium, Nickel and titanium. Tubes of this type produce seamless or welded seam. For example, as a support for the visor of the building, such pipe can be welded — it has an attractive aesthetics, durability, resistance to moisture condensation. Seamless pipe of this brand can long be operated in contact with aggressive environment in the chemical, petrochemical industry, metallurgy, shipbuilding. They are the basis of heat-exchange valves, muffles, parts slot furnaces, etc.

20Х23Н18В

Due to the high corrosion resistance, the steel 20H23N18 IN has broad applications in the chemical, transport, food industry. It is used for piping systems of heating, water supply. Steel 20H23N18 IN has no effect on the chemical composition of flowing water, it can be applied not only for industrial boilers and pipelines, but also drinking water. These pipes are successfully regulate the flows of various environments. They are used in construction and architecture for decoration. Because this pipe is not only aesthetically pleasing but also very resistant to weathering and corrosion. Seamless pipe of this brand is stable in contact with aggressive environment They serve as the basis of heat-exchange valves, combustion chambers etc. of furnace equipment operating when heated to 1050 °C.
