Type a flexible cast iron drainage pipe manufacturer - machine-made cast iron drainage pipe fittings

  Machine made drainage cast iron pipe --- flexible interface drainage cast iron pipe produced by centrifugal casting process
The interface is generally W-type clamp type or A-type flange socket type
Gray cast iron pipes and supporting pipe fittings connected by flexible joints for indoor and outdoor drainage and sewage pipeline systems of buildings
The connection can adopt two kinds of flexible joints: socket type and clamp type
Classification: in terms of pipeline system composition, machine-made cast iron drainage pipes can be divided into three categories: straight pipes, pipe fittings and accessories
From the interface form, it can be divided into: W-type machine-made drainage cast iron pipe, B-type machine-made drainage cast iron pipe and A-type machine-made cast iron drainage pipe
From the material point of view: ductile iron drainage pipe, gray cast iron drainage pipe
According to the interface mode, it is divided into flange socket interface and clamp interface
Features: 1 Long service life: using high-quality low sulfur and low phosphorus pig iron, with a variety of raw materials such as manganese and silicon, the molten iron solution is subjected to special casting inoculation treatment, and the grain is refined, which greatly improves the tensile strength and impact resistance of the product
The service life is more than 50 years

2
Flexible earthquake resistance: it has excellent seismic performance and can be applied to the seismic fortification of high-rise buildings
It is applicable to the leakage of axial deformation caused by various factors within 35mm, and the transverse vibration deflection can reach 31
5mm without leakage
Flange pressure plate and rubber ring are used for flexible connection, which has good sealing performance and is allowed to be within 15 DEG; Swing within the range without leakage

3
Low noise: irreplaceable quiet pipes to create a comfortable living environment

4
Strong fire protection: the fire protection performance is recognized by the world

5
High strength: impact resistance, corrosion resistance, no aging and high temperature resistance (thermal expansion and cold contraction is the common property of all kinds of drainage pipes and is a factor that can not be ignored that may cause quality problems
This product can withstand 70 & deg; continuous immersion of general domestic sewage)

6
Renewable recycling: more than 95% of the world's used iron is recycled iron after smelting, and the original characteristics of iron are maintained
Cast iron pipes and fittings can be 100% recycled, saving energy

7
Complete varieties: complete varieties of pipes and fittings can meet various design and installation requirements
