The pipe is honingovanny

We offer to delivery seamless steel honingovanny pipes, and also pipes for hydraulic cylinders raskatny (polished with rollers) according to the ISO (H8) standard. The pipe honingovanny is intended for production of sleeves, repair of hydraulic cylinders of various types and the sizes.

In production of a hydraulic cylinder a special role is played by a honingovanny pipe, raskatny (precision pipes for hydraulic cylinders), it is caused by the fact that the hydraulic cylinder sleeve very much is important – it constantly is under pressure of working liquid, lateral loading from the piston and temperature influence. All sleeves, irrespective of type, should possess quality of production, to differ in valuable properties:
• rigidity and durability to be mechanically steady;
• - to provide with wear resistance the minimum losses from friction of pistons with a cylinder surface;
• anticorrosive stability – the external case and internal surfaces;
• to structurally provide reliability of consolidations - on joints with the block and a head of the cylinder.

Honingovanny pipes (hydraulic cylinder sleeve) – honing-process

The essence of process of a honingovaniye (honing-process) is concluded in final mechanical operational development of a pipe (opening) by the special khan – the head rotating returnable progressively which contains six or more abrasive sliding whetstones. Before a honingovaniye a pipe (opening) already previously rasshlifovany / are chiseled. Such process, in fact – especially thin grinding as hon has fine-grained whetstones, and honing-process differs in purity and big accuracy.

As completing hydraulic cylinders, pipes honingovanny are issued in various assortment and different degree of a roughness, in addition protected from corrosion by a special covering from conservation structure. Earlier, in "to-honingovy the period", the raskatyvaniye of the developed surface by roller rollings was actively applied to openings of such big diameter what are in cylinders of engines. But the developing process of a honingovaniye began to replace a flaring method which in such context is less and less used today.
