Tianjin Jucai Huixin Circular Pipe Structure Welding Steel Pipe Specification Complete Support Customization

Description :

  Circular pipe is a hollow long strip of steel with a circular cross-section, mainly used for fluid transportation, building structural support, and mechanical component manufacturing. The round pipes produced by Tianjin Jucai Huixin Iron and Steel Plant have good mechanical and processing properties, which can effectively solve the problems of load-bearing and sealing in the construction of scaffolding, the laying of water and gas transmission pipelines, and the connection of steel structure frames. This product is suitable for welding steel pipe standards for general low-pressure fluid transportation, and is widely used in municipal engineering, industrial plant construction, and agricultural greenhouse skeleton fields. It is an indispensable basic material in infrastructure construction.

  This series of round pipes usually uses Q235B or Q195 hot-rolled strip steel as raw material, which is formed through high-frequency welding process, and the weld seam is firm and smooth. The common outer diameter range covers various specifications such as DN15 to DN600, and the wall thickness can be adjusted between 2.0mm and 12.0mm according to customer needs, in compliance with the national standard GB/T3091-2015 for welded steel pipes for low-pressure fluid transportation. The surface of the product can be galvanized to enhance its anti-corrosion ability, or the black tube state can be retained for subsequent coating. Each circular tube is usually 6 meters or 12 meters in length, and can also be cut to a non fixed length according to transportation conditions to ensure dimensional accuracy meets construction requirements.

  When selecting, it is necessary to clarify the specific purpose of the circular tube to determine the material and wall thickness. If used for pressurized fluid transportation, it is recommended to choose the national standard thickened round pipe and pay attention to the quality of the weld seam; If it is only used for structural support such as scaffolding or guardrails, ordinary wall thickness can be selected to reduce costs. Compared with square pipes, round pipes have better stability when subjected to uniform external pressure, but require specialized fittings or welding processes for connecting nodes. When purchasing, attention should be paid to distinguishing between seamless steel pipes and welded round pipes. The former is suitable for high-pressure and high-temperature working conditions, while the latter is more suitable for structural and transportation applications at normal pressure and temperature, to avoid safety hazards caused by material misuse.

  When installing the circular pipe, attention should be paid to the flatness of the cut. Before welding, the oil and rust stains on the port should be cleaned to ensure the connection strength. It is recommended to regularly check the condition of the anti-corrosion coating during outdoor use, especially at the weld joints where corrosion is prone to occur. If any damage is found, it should be promptly repainted or replaced. When storing, it should be neatly stacked with a raised bottom to prevent moisture and deformation. Different specifications should be classified and stored for easy access. Long term idle circular pipes should be rechecked for straightness and wall thickness uniformity before use to avoid excessive ovality caused by improper storage, which may affect installation accuracy and ensure the overall quality and safety stability of the project.
