Welding Steel Pipe for Rollers of Belt Conveyor (GB/T13792-1992)
Belt conveyors are extremely important pieces of industrial machinery, as they are used in a wide variety of industries, such as shipping, agriculture, construction, and manufacturing. The role they play in transferring goods quickly, safely and efficiently cannot be understated. Belt conveyors are constantly in motion, so it is essential that the rollers used in their construction are made from materials that can withstand the extreme conditions of their environment. This is why steel pipe is frequently used for rollers in belt conveyors, as it can handle the abrasive load of their operation.
Steel pipe has become a popular choice for rollers in belt conveyors due to its superior hardness, strength and resistance to corrosion. Steel pipe is also cost-effective, as it will last much longer than other materials, and thus, is a wise choice for a long-term solution. The use of steel pipe for rollers in belt conveyors is regulated by the standard GB/T13792-1992.
The standard outlines the requirements for welding steel pipe used in the production of rollers for belt conveyors. In particular, welding procedures and quality must meet the following requirements:
1. The welding seams shall be smooth and free from discontinuity, defects, and other faults.
2. The mechanical properties of weldments shall meet the requirements of the product specification and shall comply with requirements as specified in Table 1.
3. Welder qualification examination shall be conducted in accordance with the relevant regulations.
4. The defects caused by welding shall be inspected and repaired.
5. Non-destructive tests for welds shall be conducted according to the relevant regulations.
6. The unpainted welded steel shall be polished using an electric brush.
7. Only qualified welders with valid qualification certificates shall be used for welding.
steel pipe is an excellent material for welding rollers for belt conveyors, as it is highly durable and cost-effective, meeting the requirements of GB/T13792-1992. Properly welded steel pipes need to be inspected for any discontinuity and defects and should be durable enough to withstand the operating conditions of the belt conveyors. Welders should always ensure they are qualified, and the welding procedures and quality must be up to the standards of GB/T13792-1992, in order to ensure the best possible performance and lowest cost of ownership.
