Integrated house door frame P-type tube, 30*65 embossed P-shaped welded tube size

1. **Integrated House Door Frame P-Type Tube Dimensions and Features** - **Sectional Dimensions** - **Width and Height**: For the 30*65 integrated house door frame P-type tube, 30mm represents the width of the tube, which needs to be considered in the door frame structure design for compatibility with the door and for space requirements of installing door locks, hinges, and other accessories. The 65mm height of the tube provides sufficient structural strength to support the door's weight and ensures the stability of the door frame during use in the integrated house. - **Groove Dimensions (if applicable)**: If the P-type tube features grooves for installing doors or other attachments (such as sealing materials), the groove width may range from 10 to 15mm, with a depth of approximately 20 to 30mm. Such groove dimensions facilitate door installation and can effectively accommodate sealing strips and other materials, ensuring the door's sealing and soundproofing performance. - **Flange Dimensions**: - **Flange Width and Thickness**: The flange width is generally between 4 and 8mm, serving primarily to enhance the connection strength between the P-type tube and other components (such as wall panels, thresholds, etc.). The flange thickness is usually slightly thinner than the tube's main wall thickness, around 0.8 to 1.2mm, ensuring connection strength while allowing some flexibility during processing and installation. - **Wall Thickness**: - **Wall Thickness Range**: The wall thickness typically ranges from 1.2 to 2.0mm. This thickness range allows the P-type tube to withstand the impact forces of door opening and closing as well as vibrations during transportation or use in the integrated house, ensuring the structural integrity of the door frame. - **Length Specifications**: - **Standard and Custom Lengths**: The standard length is usually 6 meters, facilitating production, transportation, and storage. However, in the actual production of integrated house door frames, custom lengths such as 3 meters or 4 meters can be made according to specific design requirements to reduce on-site cutting and assembly work, improving installation efficiency. 2. **30*65 Flanged P-Shaped Welded Tube Dimension Details (Considering Welding Factors)** - **Welding Bevel Dimensions (if required)**: - **Bevel Angle and Depth**: If welding is necessary during the manufacturing process of the P-type tube with a wall thickness of 1.2 to 2.0mm, the welding bevel angle is generally between 30° and 60°, with a bevel depth of about 1/3 to 1/2 of the tube's wall thickness. Such bevel dimensions are conducive to the formation of the weld seam during welding, ensuring welding quality. - **Weld Seam Size Requirements**: - **Weld Seam Width and Height**: The weld seam width is typically controlled between 3 and 6mm, with a height of approximately 1.5 to 3mm. The weld seam size should be moderate; excessively wide or high seams may affect the appearance and dimensional accuracy of the P-type tube, as well as increase welding costs and time; while overly narrow or low seams may result in insufficient welding strength. - **Control of Dimensional Deviation After Welding**: - **Overall Dimensional Deviation**: After welding, the P-type tube's lengthwise dimensional deviation should be controlled within ±5mm, and the width and height deviations within ±0.5mm. This is to ensure that the door frame P-type tube can be properly matched with other components during installation, avoiding issues such as excessively large or small gaps.
