International standards:According to international standards, the allowable deviation value of seamless pipe wall thickness should comply with the following regulations:1. For seamless steel pipes with wall thickness > or = 20mm, the allowable deviation value should be within plus or minus 10%;2. Fo

Seamless tubes, like seamless pipes, are produced without a joint and are known for their high-quality performance in various applications. The ovality of a seamless tube refers to the degree of circularity deviation from a perfect circle. It is an important parameter as it affects the tube's streng

Spiral welded steel pipes are produced by spiral submerged arc welding or double-sided submerged arc welding process. The workshop hoisting specifications for spiral welded steel pipes mainly include the following aspects:1. Lifting equipment: The workshop should be equipped with suitable lifting eq

Welded steel pipes offer a variety of advantages that make them suitable for a wide range of applications in industries such as construction, oil and gas, water supply, and more. Here are some key advantages:1. Strength and Durability: Welded steel pipes are known for their high strength and durabil

1. Measuring Tape or Ruler:One of the simplest methods to measure the length of a spiral welded steel pipe is to use a measuring tape or a ruler. This involves physically wrapping the tape or ruler around the circumference of the pipe at the desired location and then extending it to the full length

1. Measure the Outside Dimensions:Use a measuring tape or a ruler to measure the outside width and height of the square tube. Place the measuring device at one end of the tube and extend it to the opposite end. Ensure that the measuring device is aligned perpendicular to the sides of the square tube

1. Secured Pallets or Racks: Store square and rectangular tubes on pallets or racks that are strong enough to support the weight of the tubes. Ensure that the tubes are securely placed to prevent them from sliding orppling over.2. Separation: Avoid stacking tubes directly on top of each other to pre

1. Scratches or Scuffs:Defect: Scratches or scuffs on the inner or outer surface of the pipe can occur during the perforation process.Prevention: Use proper lubrication and cooling during the piercing process. Ensure that the equipment and tools used are in good condition and free from any sharp edg

Galvanized square tube is a kind of metal tube with square cross-section, which is usually used for building decoration, automobile components, steel structure and other fields.Classification of galvanized square tube can be divided into two categories: structural steel and general purpose steel.
