45-degree Elbow Pipe Fitting

  • 45 deg radius

YANHAO is a professional elbow manufacturer, supplier and exporter. We can produce long radius 45-degree seamless elbows (ASME B16.9 standard). These elbows are made of carbon steel, stainless steel or alloy steel materials, with small flow pressure loss, strong system compatibility, and will not easily cause corrosion, pitting, rust, or wear in the pipeline system. At the rated operating temperature and pressure, the service life reaches more than 50 years. It can be connected to other pipelines through welding neck flanges, threaded flanges and socket welding flanges.

According to the project requirements, we can also produce other non-normal angle elbows including 60°, and also customize elbows with different wall thicknesses as required.

YANHAO typically uses the following elbow material grades:

  • Carbon Steel: ASTM A105, 20#, Q235, 16Mn, Q345b, ASTM A350 LF1, LF2 CL1/CL2, LF3 CL1/CL2, ASTM A694 F42, F46, F48, F50, F52, F56, F60, F65, F70.
  • Stainless Steel: ASTM A182 F304, 304L, F316, 316L, 1Cr18Ni9Ti, 0Cr18Ni9Ti, 321, 18-8.
  • Alloy Steel: ASTM A182 F1, F5a, F9, F11, F12, F22, F91, A182F12, A182F11, 16MnR, Cr5Mo, 12Cr1MoV, 15CrMo, 12Cr2Mo1, A335P22, St45.8/III.

These materials possess excellent abrasion resistance, corrosion resistance, and heat resistance, and can be widely used in the power, metallurgy, mining, and chemical industries for the transportation of sand, stones, coal powder, slag, aluminum liquid, and corrosive media. They are also suitable for high-temperature steam transportation pipelines, water-gas pipelines, and other transportation pipeline systems.

short Radius Elbow

Different from long radius elbow, short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R = 1.0D (D is the diameter of the elbow, R is the radius of curvature); short radius elbow is generally used in occasions with limited size or in low-pressure fluids. In addition, short radius elbows are also used as special solid particle conveying pipelines in some cases to reduce friction and scouring. Generally, short radius elbows are used in places where the installation environment is relatively cramped.

According to different manufacturing methods, it can be divided into push elbow, extrusion elbow and welded miter elbow. Push elbows and squeeze elbows are commonly used on small and medium-sized pipes. Welded miter elbows are used on large-size pipelines. When the miter angle of the miter elbow is greater than 450, it is not suitable to be used on pipelines with highly toxic or flammable media, or withstand mechanical vibrations and alternating loads caused by temperature changes. on the pipeline

FAQ

  • By angle: Common ones are 45, 90, 180 and others
  • By manufacturing method: push, stamping, butt welding.
  • By material: stainless steel, carbon steel, alloy steel, each has a subdivided steel grade, I told you last time, you can check the previous chat
  • By connection method: welded elbow, threaded elbow, clamp elbow

The 3D elbow has a larger bending radius than the long radius elbow, and its bending radius is three times the nominal diameter of the connected pipe (R=3D). This design is often called a large radius elbow. It has similar functions to long radius elbows and short radius elbows, but due to its larger bending radius, the 3D elbow requires more space when installed.

The wall thickness of the elbow is generally selected according to the wall thickness of the pipe. The wall thickness is generally divided into: Sch5S, Sch10S, Sch40S, Sch80S, Sch10, Sch20, Sch30, STD, Sch40, Sch60, XS, Sch80, Sch100, Sch120, Sch140, Sch160, XXS.

If it is customized, it can be made according to the customer’s drawings, or the customer can provide other pipe thicknesses in the working environment, or fluid properties, pressure and other related data for our engineers to select for them.

The main treatments include sandblasting, anti-corrosion paint, polishing, galvanizing, etc. These treatments are mainly for corrosion prevention and aesthetics.

The difference between a long radius elbow and a short radius elbow is the length of their circle radius. The long radius elbow has a larger curvature and occupies a larger area, which means that the internal fluid has enough space to bend during transportation. It is relatively stable and smooth, but it is not suitable for some places with limited space. Short radius elbows must be used, which occupy a smaller area and are more suitable for use in narrow spaces.

Yes, flanges and elbows can both be connected to pipes. The commonly used connection method does not require this operation, but it can be used in places that need frequent maintenance.
Because the flange is easy to disassemble, after the elbow is welded to the flange, the flange is connected to the pipe, so that the bend can be disassembled, which is convenient for later inspection and maintenance.

Thread refers to a connection method of flange elbows. Thread means that the threads inside the flange and elbow just match the threads on the pipe, which is like the relationship between screws and nuts. They can be connected by tightening them directly. Welding is usually used for connection, but welding cannot be used in some environments, so threads are needed.
