The spiral steel pipe and the steel roll tube are welded steel pipes, which are very different in the production process. The spiral steel pipe is a spiral seam steel pipe based on
The conveying fluid pipe seized the seasonal changes with decreased temperatures in late autumn, and took a reasonable start -stop cooling tower to run the fan and the work measure
Spiral steel pipes are mainly used for water supply engineering, petrochemical industry, chemical, electricity, agricultural irrigation and urban construction. Used for liquid tran
1. Pseudo -inferior steel pipes are prone to folding. Folding is a variety of folding lines formed on the surface of the steel pipe, which often runs through the vertical direction
The spiral tube is prone to cracks in thermal treatment cooling. What are the aspects of attention during the production process to avoid cracks? 1. After quenching, you should rec
1. If the gap is too large, the neighboring effect will be reduced, the temperature of the vortex is insufficient, and the welding seam crystals are indirectly combined with the mo
How to classify the spiral steel pipe? The irrigation system of thermal expanded steel pipeline can be divided into portable, semi -fixed and fixed forms according to the method of
The spiral steel pipe has a very important role in our lives. The following is based on the thermal treatment process of the spiral steel pipe to introduce the common defects of ea
The spiral tubes are generally not allowed to put so much stock in the production workshop in the use of the square hand, which requires the dealers to place some stocks. However,
Pipe transportation, as an efficient, special transportation method, has played an increasingly important role in the fields of oil and gas transportation. At present, large -calib
The hot -dip galvanized pipe causes the melting metal to react with the iron -based body to generate the alloy layer, which combines the substrate and the coating. The hot -dip gal
Galvanized steel pipes are based on their own high toughness, good bending and welding properties, but they are mainly made of important components with high abrasion resistance an
