Structural characteristics and application industries of T-shaped pipe supports

Structural characteristics of T-shaped pipe support

T-shaped pipe support is a common pipeline support device, whose structural design is centered around a "T" - shaped cross-section, and achieves stable support of the pipeline through a reliable mechanical layout. The following are its core structural characteristics:

T-shaped section design

Main structure: It is welded from vertical upright plates (support plates) and horizontal bottom plates (fixed plates), forming a "T" - shaped cross-section.

Mechanical advantages: The vertical load of the pipeline is borne by the vertical plate, and the stress of the bottom plate is dispersed to the foundation structure, confirming the stability of the support.

Standardized adaptation: The dimensions of the vertical and bottom plates are customized according to the pipeline specifications, with common models covering DN20-DN1200 pipe diameters and compatible with various materials such as seamless steel pipes and welded steel pipes.

materials and processes

Material selection: The main body is made of Q235B carbon steel, and 304/316 stainless steel is selected for scenarios with high corrosion resistance requirements (based on actual reports).

Anti corrosion treatment (based on actual reports): hot-dip galvanizing or epoxy coating enhances weather resistance and extends outdoor service life.

Process innovation service: The vertical plate and the bottom plate adopt groove welds, with a weld grade not lower than the second level standard of GB/T 985.1, and the connection strength is confirmed.

Function expansion design

Shock absorption structure: Some models are equipped with polytetrafluoroethylene (PTFE) or rubber shock absorbers to reduce pipeline vibration transmission.

Adjustable bracket: achieve ± 50mm horizontal adjustment through the design of the bottom plate long hole, adapting to on-site installation deviations.

Combination application: It can be used in conjunction with spring support hangers, guide brackets, etc. to form a multidimensional support system.

The application industry of T-shaped pipe supports

T-shaped pipe supports, with their structural advantages, are widely used in industrial scenarios that require high stability for pipeline support, including:

Petrochemical industry

High temperature and high pressure pipeline: a pipeline that supports the transportation of crude oil and refined oil in refining units, capable of withstanding high temperatures of 350 ℃ and pressures of 10MPa.

Corrosion prevention (based on actual reports) scenario: In coastal refineries, stainless steel pipe supports resist salt spray corrosion and have a confirmed service life of over 10 years.

Typical case: In a 10 million ton oil refining project, the DN800 steam pipeline adopts a combination of T-shaped pipe supports and spring support hangers to reduce the damage of thermal stress to the pipe supports.

Power industry

Boiler system: supports the main steam pipeline (temperature 540 ℃, pressure 25MPa) to prevent pipeline sagging and seal failure.

Steam turbine auxiliary equipment: fix the condensate and feedwater pipelines to avoid vibration induced unit resonance.

Anran verification: Through stress calculation in accordance with the "Technical Regulations for Design of Steam and Water Pipelines in Thermal Power Plants" DL/T 5054-2016, it has been confirmed that the bearing capacity of the pipe support meets the standard.

Metallurgical Industry

Blast furnace gas pipeline: supporting DN1400 gas main pipe, capable of withstanding temperature differences between 80 ℃ and -20 ℃ environments, and preventing corrosion caused by condensed water.

Continuous casting machine cooling water system: fix DN300 stainless steel pipes, confirm water flow stability, and avoid fluctuations in steel billet quality.

Industry standard: Complies with the requirements of the "Design Code for Water Supply and Drainage of Steel Enterprises" GB 50721-2011 for the stiffness of pipeline supports.

municipal engineering

Comprehensive pipe gallery: supporting DN200-DN600 water supply and drainage pipelines, with spacing set according to the "Technical Code for Urban Comprehensive Pipe Gallery Engineering" GB 50838-2015, usually 3-6 meters.

Seismic design: using limit type T-shaped pipe supports, combined with rubber isolation bearings, to meet the requirements of an 8-degree earthquake intensity.

Economy: Compared to traditional concrete piers, the single point cost is reduced by 40%, and the construction period is shortened by 60%.

Other industries

Shipbuilding: supporting fuel and oil transportation pipelines, certified by China Classification Society (CCS), suitable for temperature changes from -40 ℃ to 60 ℃.

Pharmaceutical industry: Fixed purified water and injection water pipelines, made of materials that comply with FDA 21 CFR 177.2600 level standards.

Data center: supports chilled water pipelines, reduces PUE values with shock absorbers, and assists in the construction of green data centers.
