Large diameter welded pipe typically refers to steel pipes with a diameter of 24 inches or greater. These pipes are typically used for oil and gas transmission, water supply, and other industrial applications.The manufacturing process for large diameter welded pipes involves several steps. First, th

For long-term storage and maintenance of seamless tubes, it is important to follow these recommendations:1. Clean and Inspect: Before storing seamless tubes, clean them thoroughly to remove any dirt, debris, or moisture. Inspect the tubes for any signs of damage or corrosion.2. Proper Storage: Store

1. Clean and Scrub: First, thoroughly clean the rusted steel pipe to remove any dirt, debris, and scale. Use a stiff brush or wire brush to scrub the pipe and remove any stubborn rust deposits.2. Apply Rust Inhibitor: After cleaning, apply a rust inhibitor to the steel pipe to prevent further corros

Welded pipes have a relatively long service life compared with other metal pipes. However, the service life can be affected by various factors, including the material quality, welding quality, internal and external pressure, environmental conditions, and usage conditions.1. Material Quality: The mat

Drainage is a very important issue in the construction industry. In order to ensure the waterproofing and durability of the house, the building drainage system must have an efficient and reliable design. Among them, the pipeline system is a crucial link. In order to ensure the quality of the piping

1. Location: The storage area should be well-ventilated, dry and protected from the elements. It should also be easily accessible for inspecting, handling, and loading/unloading the pipes.2. Stacking: Pipes should be stacked in a way that prevents deformation or damage. They should be supported even

1. Coatings: Applying protective coatings on the carbon steel pipe's surface can help prevent corrosion. Coatings like epoxy, polyethylene, or fusion bond epoxy (FBE) provide a barrier against moisture and corrosive substances.2. Cathodic Protection: This method involves using a sacrificial anode or

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
