Pipe elbows
Pipe elbows are used to be installed between two lengths of pipe or tube allowing a change of direction,usually these elbows distinguished by connection ends. The ends of pipe elbows may be machined for butt welding , threaded , or socketed , so the elbows are consist of butt weld,thread elbow, socket elbow and other series.
Definition of Pipe elbows
An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 90° or 45° angle, though 22.5° elbows are also made.
The ends may be machined for butt welding, threaded (usually female), or socketed, etc. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.
Pipe elbows draws >>
Pressure: SCH5 to SCH160
Size range: 1/2 to 56 inches (DN 15 to DN 1,400mm), 22.5 Deg, 45 Deg, 90 Deg, 180 Deg
Manufacturing standards: ANSI, ISO, JIS and DIN
Process: butt welding, seamless, threaded , or socketed
Elbows are categorized based on various design features as below:
Long radius (LR) pipe elbows >>
Short radius (SR) pipe elbows >>
Long Radius (LR) Elbows – radius is 1.5 times the pipe diameter
Short Radius (SR) Elbows – radius is 1.0 times the pipe diameter
90 Degree Elbow – where change in direction required is 90°
45 Degree Elbow – where change in direction required is 45°

Abrasion resistant ceramic lined elobw:
SHS-self-propagating ceramic composite steel pipe and fittings, the new generation of wearable and corrosion resistant engineering pipeline, belongs to "863" Hi-tech Plan products. It is mainly used as grindable granule and corrosives in electric power, metallurgy, mining, coal, and chemical industry when transporting sandstone, coal fines, clinker, and aluminum liquid, etc.
It is the ideal wearable and corrosion resistant engineering pipeline, with wear resistance 15 times higher than common steel pipe, smooth inner surface, and favorable liquor resistance.
Features of Alumina Ceramic lined elbow:Alumina is a cost effective and widely used material in the family of engineered ceramics. Alumina ceramics have been developed and optimized for maximum wear resistance and corrosion resistance.
Rare Earth Wear Resistant alloy Elbow
We are manufacturer of Rare Earth Wear Resistant alloy Elbow and supply high quality Rare Earth Wear Resistant alloy Elbow in both large and small quantities worldwide and offer you the best prices in the market.
The late eighty`s, American technology of rare eath wear resistant steel was introduced into our country. The relevant experts researched and made many experiments. The rare-earth wear-resistant steel had occupied the main position.Rare-earth wear-resistant steel is based on 40 steel. Cr, Ni, Si, Mo, Mn, Re elements are mixed in 40 steel forming low alloy steel which carbon content is 0.35~ 0.45%.
Bi Metal Clad elbow
Bi Metal Clad elbow is cast with mold vanishing vacuum suction casting cladding process. Outer of straight pipe is common steel pipe, cladding realized by forming high chromium lining via centrifugal forming technique.
Ceramic Tile Lined Elbow
Ceramic Tile Lined Elbow has very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface. Ceramic Tile Lined Elbows havs very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface. Ceramics with very low friction factor at low impingement angles decreases the abrasion of materials maximally. Its low density makes it easy to carry and install. Furthermore, its diamond-like hardness, fine grain structure and superior mechanical strength are the unique features that make it a wide range of demanding applications, such as coal preparation, power generation, iron and steelmaking, cement, asphalt, dredging, mining and mineral processing, oil and gas drilling. Metals have good ductility but poor resistance to abrasion - which means that abrasion prevention is required when metal pipes are used in high-temperature fluid catalyst service. On the other hand, ceramics possess great hardness and abrasion resistance, but they are brittle. Metal Ceramic double pipe is a hybrid pipe using metal as an outer pipe and a ceramic material for inner pipe segments, applied together to utilize the two materials' advantages. Hence excellent wear-resistance and good corrosion resistance of the ceramics and high strength and toughness of metal can be well combined to get a comprehensive advantage of wear-resistance, corrosion-resistance and anti-scaling. They are suitable for applications in heavy wear working conditions.
