35crmo Steel Pipe Tee is an alloy structural steel with high static strength, impact toughness and high fatigue limit.
35CrMo steel material belongs to alloy structural steel. 35 refers to the carbon content of about 35%, Cr is chromium, and Mo is molybdenum.
35CrMo steel material has high static strength, high impact toughness, high fatigue limit, higher hardenability than 40Cr steel, high temperature resistance, long-term working temperature can reach 500 ℃, poor welding performance.
The main applications of 35CrMo steel material are: it can be processed into important structural parts working under high load, such as the transmission parts of vehicles and engines; the rotor, main shaft, transmission shaft of heavy load and large section parts of turbogenerator.
35CrMo is an alloy structural steel that is commonly used in various applications. It has high static strength, impact toughness, and a high fatigue limit. The hardenability of 35CrMo is higher than that of 40Cr, another commonly used alloy steel. The carbon content of 35CrMo is around 35%, and it contains chromium (Cr) as well.

Application: 35CrMo alloy pipe is used to manufacture important parts of various machines that bear the impact, twist and high
In the behavior, we make beveling after shot blasting, bevel ends are fully machined by advanced equipment Double Beveling Machine ensure the height, length, thickness, O.D. and I.D. are all qualified.
Welding Bevel acc. to
The ends of all buttweld fittings are bevelled, exceeding wall thickness 4 mm for austenitic stainless steel, or 5 mm for ferritic stainless steel. The shape of the bevel depending upon the actual wall thickness. This bevelled ends are needed to be able to make a “Butt weld”.
ASME B16.25 covers the preparation of buttwelding ends of piping components to be joined into a piping system by welding. It includes requirements for welding bevels, for external and internal shaping of heavy-wall components, and for preparation of internal ends (including dimensions and dimensional tolerances).
Our in-hourse R&D team developed bevel ends equipment are good using in thickness 2mm to 20mm pipe fittings, guarantee high efficiency and high quality.

For the manufacturing process of all pipe fittings, forming is an indispensable process. Because the forming process of different products is different, it needs a long time.
Heating
In order to meet the requirements of material deformation in the forming process, it is necessary to heat the blank when the tube is manufactured by hot forming method. The temperature usually depends on the material and heating process.
During the forming of hot pushing elbow or hot bending elbow, the medium frequency or high frequency induction heating method is usually used, and the flame heating method is also used. This kind of heating mode is continuous heating which is synchronous with the forming process of elbow or elbow. The tube blank is heated in motion and the forming process is completed.
When hot pressing elbow, hot pressing tee or forging are formed, the heating method of reverberatory furnace, flame heating, induction heating or electric furnace heating are usually adopted. This kind of heating is to first heat the tube blank to the required temperature, and then put it into the die for pressing or forging.
Welding
There are two kinds of pipe fittings with welding seam. One is the pipe fittings made of welded pipe. For the pipe fitting manufacturer, the forming process of welded pipe is basically the same as that of seamless pipe, and the forming process of pipe fitting does not include welding process; the other is that the pipe fitting manufacturer completes the welding process required for pipe fitting forming, such as the elbow formed by assembling and welding after single piece pressing The tee pipe is welded into tube blank after being rolled by steel plate drum, etc.
The commonly used welding methods of pipe fittings are manual arc welding, gas shielded welding and automatic welding.
Our factory guides the welding work according to the preparation of the welding procedure specification, and carries out the welding procedure qualification according to the corresponding specification requirements, so as to verify the correctness of the welding procedure specification and evaluate the welding ability of the welder.
One of the most common manufacturing methods for caps, where plate is cut out in a circle and formed by deep drawing.
Deep drawing is the manufacturing process of forming sheet metal stock, called blanks, into geometrical or irregular shapes that are more than half their diameters in depth. Deep drawing involves stretching the metal blank around a plug and then moving it into a moulding cutter called a die.
A drawing press can be used for forming sheet metal into different shapes and the finished shape depends on the final position that the blanks are pushed down in. The metal used in deep drawing must be malleable as well as resistant to stress and tension damage.
Pipe Tees are widely used in various commercial and industrial applications. Industrial applications include.
We are manufacturer of Reducing tee and supply high quality Reducing tee in both large and small quantities worldwide & offer you the best prices in the market.
Visual Inspection is conducted on fittings to check any surface imperfections. Both fittings body and weld are checked for any visible surface imperfections such as dents, die marks, porosity, undercuts, etc. Acceptance as per applicable standard.
For packing of carbon steel flanges with painting,we would use the bubble wrap to protect the painting.For flanges without painting or oiled with long-term shipment,we would suggest client to use the anti-tarnish paper and plastic bag to prevent the rust.
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
