Fire steel pipe construction
(1) When the steel pipes of the fire hydrant water supply system adopt hot-dip galvanized steel pipes on the inner and outer walls, welding should not be used. When the system pipeline adopts a non-corrosive inner wall pipeline, it can be connected by welding, but the pipeline...Read more -
Steel structure maintenance and upkeep
1. Regular rust and anti-corrosion protection. Generally, the designed service life of steel structures is 50-70 years. During the use of steel structures, the chance of being damaged due to overload is very small. Most steel structure damage is caused by corrosion that reduce...Read more -
Why are large-diameter steel pipe mostly welded with steel
1. The uses of large-diameter stainless steel can be divided into oil well pipes (casing, oil pipes drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structural pipes, hydraulic support pipes, gas cylinder pipes, geological pipes, and chemical pipes (high-pressure f...Read more -
What is the difference between butt welding flange and flat welding flange
The butt-welded flange is that the pipe diameter and the wall thickness of the interface end are the same as the pipe to be welded, and it is welded just like two pipes. The flat welding flange is a concave platform that is slightly larger than the outer diameter of the pipe a...Read more -
Comparison of steel pipe anticorrosive coating technology
Steel pipe anti-corrosion coating process 1: Due to the use of curtain coating, the coating film sags seriously. Besides, due to the unreasonable design of the roller table and chain, the coating film has two longitudinal and multiple circular scratches. This process is remove...Read more -
What are the detection methods of oil casings
1. Ultrasonic detection When the ultrasonic wave is spread in the detected raw material, the acoustic properties of the raw material and the transformation of the internal tissue will have a positive effect on the spread of the ultrasonic wave. After detecting the level and co...Read more -
What is the rust removal method of welded steel pipe and its importance
The anti-corrosion of buried steel pipes is a key procedure to ensure and prolong its service life. To ensure that the anti-corrosion insulation layer is firmly combined with the pipe wall, rust removal of the pipe is the most important. Generally, the rust on the surface of t...Read more -
Characteristics of straight seam steel pipe
Straight seam steel pipe generally refers to the use of a special process to carry out anti-corrosion treatment on ordinary steel pipes, so that the anti-corrosion ability of the steel pipe is generally used for waterproof, rust, acid and alkali, and oxidation resistance. The ...Read more -
How to clean straight seam steel pipes
(1) We can use solvents or emulsions to clean the surface of the steel pipe. This method is very effective for the oil and grease or dust and other organic matters on the surface of the steel pipe. (2) In the case of rust on the surface of the steel pipe, we can use a steel wi...Read more
