The central pipe fixing seat is a device used to fix various pipelines, rods, etc. It has a wide range of applications in different fields. The following is a detailed introduction about it:

application area 

Bicycle field: In the bicycle frame, the middle pipe fixing seat is used to fix the middle pipe and support the seat. As for the adjustable bicycle frame with adjustable seat, the middle pipe fixed seat is matched with the adjustment plate on the middle pipe bracket, and the position of the middle pipe and seat is adjusted through the engagement of screws and buckles to meet the riding needs of different users.

In the field of home furnishings, it can be used to fix wardrobe hanging poles, balcony drying poles, curtain poles, etc. The stainless steel pipe hanger rod fixing bracket is usually in the form of an open flange seat, which is fixed by screws to provide stable support for the hanger rod and ensure its load-bearing capacity.

In the field of construction and pipeline engineering: In heating pipelines, water supply and drainage pipelines and other pipeline systems, the central pipe fixing seat is used to support and fix the pipeline, limit the displacement of the pipeline, withstand the forces caused by the gravity, internal pressure, external load and temperature changes of the pipeline, and transmit these forces to the structure of the pipeline. According to the restriction of pipeline displacement by supports, there are two types: movable supports and fixed supports. Among them, fixed supports can limit the expansion and contraction displacement of pipelines and withstand the thrust of pipelines.

In the field of machinery and equipment: In some mechanical equipment, such as the boom extension system of a truck crane, components similar to the middle pipe fixing seat are used to fix the extension rope and hinge axis, in order to achieve synchronous extension and contraction of each section of the boom, ensuring the stability and accuracy of the boom extension and contraction.

Material and Characteristics

metal material

Stainless steel: such as 304 stainless steel, has good corrosion resistance, strength, and toughness, can adapt to various harsh environments, is not easy to rust and corrode, and is commonly used in occasions with high requirements for corrosion resistance, such as pipeline fixation in bathrooms, kitchens, and outdoor heating, water supply and drainage pipelines.

Carbon steel: has high strength and relatively low cost, but poor corrosion resistance. It generally requires surface treatment such as galvanizing, painting, etc. to improve its corrosion resistance. It is commonly used in situations where corrosion resistance is not high but strength and cost are required, such as pipeline fixation in building structures.

Aluminum alloy: light weight, good corrosion resistance, good processing performance, can be made into fixed seats of various shapes and sizes, commonly used in occasions with weight requirements, such as bicycle frames, furniture, etc.

plastic material

Nylon: It has good wear resistance, corrosion resistance, and insulation properties, is lightweight, and has low cost. It is commonly used in situations where weight, corrosion resistance, and insulation are required, such as fixing wires and cables, and fixing small pipelines.

PVC: Strong corrosion resistance, low price, good insulation performance and weather resistance, commonly used for fixing building water supply and drainage pipelines, electrical pipelines, etc.

structure type 

Flange type fixed seat: composed of a flange plate and connecting components, the pipeline is connected to the fixed seat by bolts or welding, and the connection is firm, with good sealing performance. It is commonly used for fixing large-diameter pipelines or pipelines with high sealing requirements.

Clamp type fixing seat: using clamps to hold the pipeline tightly, fixing the clamps with bolts or other fastening devices, easy to install and remove, suitable for fixing pipelines of different diameters, commonly used in some pipeline systems that require frequent disassembly or maintenance.

Clamp type fixing seat: Similar to clamp type fixing seat, but the shape and structure of the clamp may be different. It is usually made of steel strip or steel plate and fixed to the pipeline by bolts or other fastening devices, with good clamping force and stability. It is commonly used for fixing circular pipelines.

Saddle type fixing seat: shaped like a saddle, the pipeline can be placed inside the saddle and fixed to the support structure with bolts or other fastening devices, providing good support and fixation for the pipeline. It is commonly used for fixing horizontal or inclined pipelines.
