Manufacturing Standards for Crane Tubes

1.Definition

Crane pipe is a type of pipeline connecting component used for transporting fluids or gases, commonly used in industrial fields such as chemical, petroleum, pharmaceutical, and food industries.  This standard applies to the manufacturing process of crane tubes and aims to ensure their quality and reliability.

2. Material requirements

2.1 The manufacturing materials of crane tubes should comply with relevant material standards or specifications, and have good corrosion resistance and low permeability.

2.2 Material requirements should include the chemical composition, mechanical properties, and physical properties of the material, and should undergo necessary testing and verification.

3. Dimensional and geometric requirements

3.1 The size and geometric requirements of the crane tube should comply with the requirements of the design drawings or relevant technical documents.

3.2 The inner diameter, wall thickness, length and other dimensions of the crane tube should meet the design requirements, and necessary measurements and verifications should be carried out.

4. Manufacturing process requirements

4.1 The manufacturing process of crane tubes should ensure the sealing and mechanical strength of their connecting parts.

During the manufacturing process, appropriate processing methods such as cold drawing, cold rolling, forging, etc. should be used to ensure that the size and surface quality of the crane tube meet the requirements.

The welding process of the crane tube should comply with relevant welding standards or specifications, and necessary weld seam testing and evaluation should be carried out.

The surface treatment of crane tubes should comply with relevant anti-corrosion requirements and necessary testing and verification should be carried out.

5. Testing and acceptance requirements

The manufacturing process of crane tubes should undergo necessary inspections, including material testing, dimension testing, weld seam testing, etc., to ensure their quality and reliability.

5.2 The acceptance of crane tubes should comply with relevant acceptance standards or regulatory requirements, and necessary acceptance records and testing reports should be conducted.

6. Identification and packaging requirements

6.1 The identification of crane tubes should include necessary information such as the manufacturer's name, product model, and product specifications, and should comply with relevant identification standards or specifications.

6.2 The packaging of crane tubes should comply with relevant packaging standards or specifications, and ensure that they are not damaged during transportation and storage.

7. Quality management requirements

7.1 The manufacturing process of crane tubes should establish and implement a quality management system, and necessary process control and quality records should be carried out.

7.2 The manufacturing unit of crane tubes should develop and implement a quality control plan, and conduct necessary internal audits and inspections.

This standard only provides technical guidance for the manufacturing of crane tubes, and specific implementation should refer to relevant industry standards, specifications, and legal requirements.  In the actual manufacturing process, reasonable adjustments and improvements should be made according to specific circumstances.
