1. Pipeline System Overview:
In order to transport liquids or gases, you must use a variety of channels, pipelines, in addition to straight pipes other than steel, but also use all kinds of pipe fittings: pipe bend elbow must be used, when to use the size of variable diameter pipeline
Head, fork to use when the three links connecting pipe joints and when to use flanged joints, open transmission medium to achieve the purpose, but also with various valve, reduce heat to shrink or expansion of the piping system vibration frequency shadow
Ring, but also with the expansion joint. In addition, pipeline, there are a variety of instruments connected with the various joints plug so. We used the pipeline system, in addition to other accessories other than the straight collectively referred to as pipe fittings.
2. Metallic materials common sense:
Metal is our daily life and industry the most widely used material. It consists of steel, iron and several types of non-ferrous metals, of which the steel is the most common material most widely used
Expected, the major component is iron, steel, and the rest are man-made and various alloying elements added impurities. It is because of the added alloying elements of these different varieties. The number of different kinds of steel was formed
Such as ordinary carbon steel, stainless steel, alloy steel, etc., in these added elements, carbon C plays an important role.
2.1 The common chemical elements in steel:
Percentage of all steel for the majority of iron (Fe), except the other, usually contain the following types of elements (often called the steel alloying elements):
C (C) Si (silicon) Mn (manganese) P (P) S (sulfur) and
Cr (chromium) Ni (Ni) Mo (molybdenum) Ti (titanium) V (V) and so on.
Under normal circumstances, in which P, S as the impurity content, the lower the better quality steel.
2.2 Classification of Steel:
In accordance with the steel alloying elements added to the different species, we can simply be divided into three major categories of steel: carbon steel. Alloy Steel. Stainless steel.
