Product Details


Hydraulic Cylinder Pipes introduction

WUXI HENGTONG PETROLIC MACHINERY has two factories of 40000 square meters and totally 150 employees manufactures pre honed tubes, ready to hone tubes, honed tubes, skived and roller burnished tubes, chrome bar, piston rods and high-precision cold-drawn steel tubes, Honed Tubes are presicion tubes with smooth inside , they also could be skived and burnished pipe. Tubes or pipes inside tolerance could be H10, H9 or H8. Outside tolerance, wall thickness tolerance are produced according to seamless cold drawn tubes for precision application standard GB/T3639-2009 , EN10305 or DIN2391 standard. Material SAE1020, 20#, ST45, CK45, ST52, E355 tubes and so on for you to choose.
