Purchasing Guide

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

  • For procurement requirements that require the use of straight seam welded pipelines, it is recommended to prioritize the confirmation of key technical parameters such as pipe diameter, wall thickness, and material grade to ensure compatibility with the pressure and corrosiveness requirements of the conveying medium. For example, in the oil and gas field, API 5L standards must be met.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually have more stable delivery records in municipal water supply and drainage or chemical pipeline engineering.
  • In the construction of thermal pipelines, attention should be paid to the welding process and straightness index of straight seam welded pipelines. High frequency resistance welding (ERW) process is suitable for medium and low pressure scenarios, while submerged arc welding (SAW) is more suitable for long-distance high-pressure transportation.
  • There are significant differences in coating requirements for different application scenarios. For example, in marine engineering, epoxy powder anti-corrosion is required, while in coal mine underground pipelines, wear resistance is emphasized. When purchasing, specific technical specifications for the usage environment should be clearly defined.

Knowledge Base

Q

Baidu AiGou has found pictures related to different categories of straight seam pipe welding machines for you, taking you to appreciate the diversity and uniqueness of straight seam pipe welding machines. At the same time, we also recommend high-quality straight seam pipe welding machine products for you, so that you can easily and quickly find the most suitable straight seam pipe welding machine for yourself when purchasing.

Q

Plastic coated steel pipes for drainage channels are a pipeline system that combines the advantages of steel pipes and plastic materials. It forms a high-performance pipeline system by coating a layer of plastic material (such as epoxy resin or polyethylene) on the surface of steel pipes and installing them through specific groove connections. The drainage ditch coated plastic pipeline combines the high strength of steel pipes and the corrosion resistance of plastic materials.
