Causes of corrosion of cold drawn seamless pipes

1. The surface layer of the cold-drawn seamless pipe has accumulated smoke and dust rich in other chemical molecules or the appendages of the semi-animal metal material composite material inhalable pa

Pay attention when placing cold drawn seamless pipes

1. Cold-drawn seamless pipes and carbon steel pipes cannot be stacked together, because the materials of carbon steel pipes and cold-drawn seamless pipes are different. In a humid environment, if carb

Pay attention before cutting cold-drawn seamless steel pipe

1) In the area to be disconnected, please use a towel or a soft cloth to thoroughly clean the oil, dirt or soil on the surface of the cold drawn seamless pipe. (2) Try to choose a special type for sta

Cold drawn steel pipe cooling precautions

1. The supercooled austenite of the cold-drawn steel pipe is very stable and has high hardenability. Even if it is air-cooled, the martensite structure can be obtained, but air-cooling will cause oxid

Introduction and use of gas cylinder tubes

Gas cylinder tube is a general term for making seamless tubes for gas cylinders and high-pressure vessels. There are many types of gas cylinder tubes. In addition to ordinary oxygen cylinders and hydr

Material selection requirements for cold drawn pipes

Cold-drawn pipe is actually a kind of steel pipe. In the process of manufacturing, it is classified according to the difference of its production process. To a certain extent, it is different from hot

The primary working principles of a hollow reverse hydraulic cylinder

It works primarily like this: mechanical energy from host is transformed into hydraulic pressure energy with the hydraulic pump of the system. As pressure changes, control components like valves and p

How to enhance abrasion resistance of interior wall of a hydraulic cylinder?

A hydraulic cylinder consists of cylinder barrel, piston and piston rod. As time goes, some problems may appear during working. When facing such problems, we need have some knowledge of solution. At o

Effect on gravity machinery of a hydraulic cylinder barrel

In a mechanized times of today, machinery, highly effective and efficient, has been an necessity for most work or project which can’t be done merely by manpower. Machinery has also made our life far e

Some details to be noted for assembly of a hydraulic cylinder

A hydraulic cylinder is an executive unit by outputting directly proportional linear motion of force and effective area of piston and pressure difference added to its two ends, functioning as an energ

Cautions for disassembly of a hydraulic cylinder

Some problems or even damages to parts may be encountered when assembling or disassembling a hydraulic cylinder, finally causing troubles. So, cautions need to be aware of for better operation.

Repairment of flaw on a honed tube

Amid processing of a honed tube, pits on the surface of honed tube are a key factor reducing quality of a finished tube. To get a qualified honed tube, such flaws must be repaired. Here are solutions
