China Elbow Machine Manufacture

Hei yan is one of the professional manufacture of elbow machine.

With the development of steel pipe deep processing, our elbow forming machine has got all-around technology improvement. Now our elbow machine has composited over short stress line, prod cast expand diameter technology.
Hydraulic pushing elbow machine, clamp gate and load raw material we all adopt hydraulic control.

Raw material steel pipe: seamless steel pipe,welded steel pipe and rolled steel pipe.
Elbow produced scope: 25mm-1420mm  thickness:5mm-120mm
Angle: 22.5,45,90,135 degree and customer required angle.
The specification (dimension, radius, thickness) of the finished elbows can meet the stipulated international standard, such as ANSI B16.9, ANSI B16.28, DIN2605, GB12459, etc

The requirement to workshop and auxiliary equipment of China Elbow Machine:
Each machine medium frequency cooling water should above 50m3 and has the dust prevention device.
Normally require the workroom length 30-40 meters, single machine width 6-8 meters.

Welcome to contact with us for elbow machine, we also manufacture,pipe expanding machine,pipe bending machine,medium frequency heating equipment according to customer requirement.

2.Make sure that all connectors of the hydraulic pump station are equipped with oil seal rings, if the seal rings appear damaged or oil leakage, should be replace timely.

3.If found forward or backward abnormality, first check electro-hydraulic valve whether operate normal, if working normally, then you should check whether the electro-hydraulic relief valve or the one-way unloading valve has contaminant that made it could not working or not(this phenomenon usually happen when you just use this machine). If has contaminant, you should open it, clean by gasoline or diesl oil, everything is ok, then re-install.

4.Operated this equipment within 15 days, you should clean the tank and filter hydraulic oil once.

5.When cleaning tank, you should clean the inside the oil filter of tank also.
