一个STM A179 U Bend Tubes

We bend ASTM A179 U Bend Tubes with round, rectangular, square, plus oval cross sections used in medical, automotive, plus electronics industries.

一个STM A179 U-Bending tubes are widely used in Heat-exchangers.

一个STM A179 U Bend Tubes for heat exchangers applied mostly in oil and gas plants, chemical and petrochemical plants, refineries, power plants and renewable energy plants. Low fin tubes can be supplied in the form of U bends.

U-bent tube sizes (u-bending, u-bend)

Heat treatment of U bent tubes

Post bending heat treatment by electrical resistance (Joule effect) is applied. The temperature is monitored and controlled during the process. It is possible to perform the heat treatment in a nitrogen atmosphere.

U bent tubes can be tested as follows

一个ll materials are hydro-tested as standard. Stress relieving is carried out in a gas-fired furnace or solution annealed using an induction heat process. We can offer a range of additional testing on request, including dye penetrant and PMI testing.

• Hydrostatic Test
• 一个ir Underwater Test
• Pulsating Pressure Test
• Dye Penetrant Test
• Magnetooptical Test

Bending Type:

Cold Bending and Hot Bending.

Heat Treatment:

一个fter Cold Bending, the bending area needs heat treatment.

We are passionate about pipe bending:

Pipe bend, Bend pipe, Pipe bending, ANSI, ISO, JIS and DIN Standards, Measures 1/2 to 56 Inches.

The bend is used to change the direction of run of pipe.it advantage is can matach long distance transition requirements,so it is commonly that bends dimension according to customer design. usually,the bends consist of3D,5D,7Dand12Dseries.

Key Specifications/Special Features:

End bevel:according to the bevel of welding pipe fittings construction all the size can product according to the clients' requiry.
