Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • In the actual procurement process, it is recommended to prioritize checking product specifications such as pressure rating, interface size, and material compatibility to ensure compatibility with existing piping systems.
  • For applications in high-pressure scenarios such as petroleum and chemical engineering, it is necessary to pay attention to the industry data support provided by suppliers to verify the actual performance of their products under similar working conditions.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and platform statistical information to comprehensively evaluate their supply stability.
  • When used on offshore platforms or in low-temperature environments, it is recommended to confirm additional sealing performance and corrosion resistance technical parameters to avoid the risk of failure due to environmental differences.

Knowledge Base

Q

Product Features:   Also known as pipe joint or flexible joint. It is a commonly used pipeline connector that can be easily installed and disassembled. The pipe fittings connecting two pipes can be separated without moving the pipes for easy maintenance. It includes three parts: threaded head, ball head, and tight cap. The sealing surfaces inside the union include flat surfaces (with pads), spherical surfaces, conical surfaces, etc. The connection methods between the union and the pipeline include butt welding, socket welding, and screw welding

Q

High strength of threaded joints: According to the principle of cold work hardening of steel, the strength of straight threads rolled out on steel bars is greatly increased, thereby making the tensile strength of straight threaded joints higher than that of the steel bar base material. 2. Stable performance: The connection process is not affected by the quality of workers, so the performance is stable. 3. Fast connection speed: due to the use of off-site prefabrication and on-site assembly connection
