What is pipe?
Pipe is a hollow section with round cross section for the conveyance of products, including fluids, gas, pellets and powders, etc.
The most important dimension for a pipe is the outer diameter (OD) together with the wall thickness (WT). OD minus 2 times ...
API 5L generally refers to the implementation standard for pipeline steel pipes, which include two main categories: seamless steel pipes and welded steel pipes. Currently, the commonly used welded steel pipe types in oil pipelines are spiral submerged arc welded pipes ...
Steel pipes are classified by cross-sectional shape into circular, square, rectangular, and special-shaped pipes; by material into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite pipes; and by application into pipes for...
Measures to ensure welding quality include:
1. Human factors are the key focus of galvanized pipe welding control. Due to the lack of necessary post-welding control methods, it is easy to cut corners, which affects quality; at the same time, the special nature of galva...
Galvanizing is a process where a thin layer of a second metal is applied to the surface of an existing metal. For most metal structures, zinc is the go-to material for this coating. This zinc layer acts as a barrier, protecting the underlying metal from the elements. T...
Essential differences:
Galvanized steel pipes are made of carbon steel with a zinc coating on the surface to meet daily usage requirements. Stainless steel pipes, on the other hand, are made of alloy steel and inherently possess corrosion resistance, eliminating the ne...
When galvanized steel materials need to be stored and transported in close proximity, sufficient preventive measures should be taken to prevent rusting. The specific preventive measures are as follows:
1. Surface treatment methods can be used to reduce the forma...
The first step in metal processing is cutting, which involves simply severing raw materials or separating them into shapes to obtain rough blanks. Common metal cutting methods include: grinding wheel cutting, saw cutting, flame cutting, plasma cutting, laser cutting, a...
In different weather climate steel corrugated culvert construction precautions are not the same, winter and summer, high temperature and low temperature, the environment is different construction measures are also different.
1.High temperature weather corrugated culver...
Advantages of square tube
High compressive strength, good bending strength, high torsional strength, good stability of section size.
Welding, connection, easy processing, good plasticity, cold bending, cold rolling performance.
Large surface area, less steel per unit su...
Carbon steel, also known as carbon steel, refers to iron and carbon alloys containing less than 2% carbon, carbon steel in addition to carbon generally contains a small amount of silicon, manganese, sulfur and phosphorus.
Stainless steel, also known as stainless acid-res...
There are mainly the following differences between galvanized square tubes and ordinary square tubes:
**Corrosion resistance**:
- Galvanized square pipe has good corrosion resistance. Through galvanized treatment, a layer of zinc is formed on the surface of the square tu...
