The cold working methods of steel pipes mainly include cold drawing and cold rolling. The raw materials of cold-rolled steel pipes can be hot-rolled seamless steel pipes or welded pipes. The common characteristics of the cold working method of steel pipes are high dimensional accuracy and good surface roughness. It can produce very thin (up to 0.05~0.01mm) thin-walled tubes and very thin (up to 0.3~0.1 mm in diameter) capillaries.

√ ES series Single-stage End-suction Horizontal Centrifugal Pumps Advantage have to say!!
1.SAVE PLACE.  √Â
These series pumps have an integrally Horizontal structure, beautiful appearance and less area of occupied land, which , comparing with the ordinary ones, is reduced by 30%.
2. Stable running, Low noise , High concentricity of assembly.  √Â
By the straight joint between the motor and the pump, the middle structure is made simplified, thus enhancing the running stability, making the impeller of a good balance of moving-resting, resulting in no vibration during running and improving the environment of use.
3.NO LEAKAGE  √Â
A mechanical seal of antiseptic carbide alloy is used for the shaft sealing so as to get rid of the serious leakage of the fillings of centrifugal pumps and ensure the operating place clean and neat.
4. EASY SERVICE  √Â
Service can be easily done without removing any pipeline because of the back-door structure.
5. VARIOUS INSTALLATION Type  √Â
Viewing from the inlet of the pump, the outlet of it can be mounted in one of the three ways, horizontally leftward, vertically upward and horizontally rightward.Â
√ Where can use our ES series Single-stage End-suction Horizontal Centrifugal Pumps ?
- Transport pure water and other liquids of the similar physical nature as pure water
- Water supply and drainage in industries and cities
- boost water-feeding of high buildings
- Park/Garden Irrigation
- Fire-fighting boost
- Remote mater-transportation
- Warming or cold-hot water circulation
- Boost in bathrooms
- Equipment completing as well.  
√  STRUCTURE DESCRIPTION of  Single-stage End-suction Horizontal Centrifugal Pumps?
Working condition
1.Pump inlet pressure is less than 0.4MPa
2.Pump system that is to say the pressure at the suction the stroke ≤1.6MPa, please notify the pressure for the system at work when ordering.
3.Proper medium: the medium for pure-water pumps should have no corrosive liquid and the volume of non-melting medium solid should not be over 0.1% of the unit volume and the graininess less than 0.2mm. Please notify at order if the medium to be used with small grain.
4.No larger than 40ºC of the ambient temperature, no higher than 1000m of the above-sea level and no more than 95% of the relative humidity.

Generally, the production process of seamless Steel Pipe can be divided into cold rolling and hot rolling. The appearance of cold-rolled seamless steel pipe is shorter than that of hot-rolled seamless steel pipe. The wall thickness of cold-rolled seamless steel pipe is generally smaller than that of hot-rolled seamless steel pipe. But the surface looks brighter than that of thick wall seamless steel pipe. The surface is not too rough, and the diameter is not too much burr.
In order to obtain seamless pipes with smaller size and better quality, cold rolling, cold drawing or a combination of the two methods must be used.
High precision cold drawn precision steel pipe is a new type of steel pipe, which is mainly characterized by high precision. There are usually two production processes of two high mill and three high mill. The precision of three high mill in producing cold rolled seamless steel pipe is higher, which can be controlled within a few wires, but the price is relatively higher.
The product specification range of cold rolled steel pipe is: outer diameter 4.0 ~ 450mm; The wall thickness is 0.04 ~ 60mm. Compared with the cold drawing method, the advantage of the periodic cold rolling method is that the shrinkage of the pass surface is large, there is no need for difficult head, and the yield is high.
