Description
As a new type of pipe material, ductile cast iron elbow is widely used in water supply, fire fighting, industrial drainage and other pipeline projects. It has advantages of simple construction, economic cost, reliable performance, good corrosion resistance and long service life.The company produces centrifugal ductile cast iron pipes in strict accordance with ISO2531 standard, adopts domestic advanced pipe manufacturing equipment.
It advanced pipe casting process and perfect process flow, from annealing to finishing, from lining to curing, from painting to packaging, and the whole process control.The company has a complete range of equipment, and adopts the advanced technology of the domestic cast pipe industry in the processes of spheroidization, annealing, health preservation and painting.And it ensure the stable production process and excellent product quality.The main components of ductile iron pipe are carbon, silicon, manganese, sulfur, phosphorus and magnesium.
Specification
Tensile strength: 420 / MPa
Yield strength: 300 / MPa
Connection: Welding
Type
A certain amount of spheroidal graphite is distributed on the ferrite and pearlite matrix. The proportion of ferrite and pearlite in the matrix structure is different. The proportion of pearlite with small caliber is generally no more than 20%, and that with large caliber is generally controlled at about 25%.Classification: socket elbow, plate bearing elbow, double bearing elbow, double plate elbow.
Degrees: 90 degrees, 45 degrees, 22.5 degrees, 11.25 degrees.Use position: elbow is often used at the turning position of the pipeline, for changing the direction of the pipeline or for connecting the valve with flange joint, etc. Elbow is the most common type of ductile iron pipe fittings, also known as elbow.
Elbow belongs to T-type (K-type) interface ductile pipe fitting, and elbow is an indispensable pipe fitting in pipe network installation engineering. In the municipal water supply network, the elbow is the most commonly used pipe fitting, which is used to change direction.
Technical data sheet

| Display | Butt welding elbow |
| Texture of material | cast iron |
| Connection mode | flange, socket and spigot |
| Size | Full-size |
| Standard | GB/T12593 |
| Advantage | Good elasticity, corrosion resistance and high pressure resistance |
| Lining | Cement mortar, Portland cement |
| Outer coating | Metallic zinc, bituminous paint |
Characteristic
Connection mode: flange, socket and spigot.Pressure withstand standard: PN10, PN16, PN25.Mechanical properties: minimum tensile strength: 420 / MPa, minimum yield strength: 300 / MPa, minimum elongation: 7%.Anti corrosion treatment: asphalt coating is used to transport gas pipeline. Preheating the pipe before painting can improve the adhesion of asphalt paint and accelerate drying.
Executive Standards: GB / T 13295-2008, ISO2531, EN545.Material: ductile cast iron.Specification: DN100, DN150, DN200, DN250, DN300, dn400, DN500, DN600, DN800, DN1000, DN1200mm.Installation: the installation interface of ductile iron pipe fittings has socket, spigot, flange interface, and the socket must be installed in place. The sealing gasket must be densified for the installation of flange interface, and the bolt shall be installed at the position.
