Type F Spring Hanger

The Type F Spring Hanger is a standard suspended spring support developed by Yangzhou Tianshun Pipeline based on 14 years of industry experience, and it is also one of the most widely used spring hanger models in the global industrial pipeline field. Since its production launch in 2012, we have manufactured over 2 million Type F Spring Hangers, exported to 45 countries and regions, and served more than 300 large-scale industrial projects worldwide. This model is designed in full compliance with internationally accepted standards and achieves 100% interchangeability with the same model products from major global manufacturers.

Design Basis and Applicable Standards

The Type F Spring Hanger is strictly designed and manufactured in accordance with the following international standards to ensure its global versatility and compatibility:

▶  ANSI/HG 20644-1998 Variable Spring Supports and Hangers

▶  GB/T 17116.1-2018 Pipe Supports and Hangers - Part 1: Technical Specifications

▶  ASME B31.3 Process Piping

▶  DIN 2545 Pipe Spring Hangers

▶  API RP 551 Design and Installation of Pipe Supports and Hangers

All products have passed the ISO 9001:2015 quality management system certification, and third-party certification documents such as CE and API can be provided upon request.

Structural Composition and Working Principle

The Type F Spring Hanger adopts an upper suspended structure design, connected to the building structure through the top lifting lug and to the pipeline through the bottom suspension rod. When the pipeline undergoes vertical thermal displacement, the spring expands and contracts accordingly, automatically adjusting the supporting force and uniformly transmitting the pipeline load to the structure to avoid stress concentration.

The standard product consists of the following components:

▶  Upper Housing: Stamped from Q345B steel plate

▶  Cylindrical Helical Spring: Manufactured from 60Si2MnA alloy spring steel

▶  Load Indicator Plate: Clearly marked with load and displacement scales

▶  Adjusting Screw Rod: Available in M16-M36 specifications for on-site load adjustment

▶  Upper and Lower Connection Lugs: Manufactured by forging process for higher strength

▶  Lock Nuts: Dual nut anti-loosening design

Core Performance Advantages and Measured Data

The above data are from 100% full inspection records of the company's laboratory. Each product undergoes strict load testing and displacement calibration before shipment.

Applicable Scenarios and Installation Methods

The Type F Spring Hanger is suitable for suspended support of most industrial pipeline systems, especially for the following scenarios:

Steam-water pipeline systems in power plants

Process pipelines in petrochemical industry

Urban central heating pipe networks

Natural gas transmission pipelines

Pharmaceutical and food processing pipelines

General industrial plant pipelines

Three installation methods are available for this model:

Single Lug Suspension: Suitable for single pipelines

Double Lug Suspension: Suitable for heavy-load pipelines

Parallel Installation: Suitable for ultra-heavy-load pipelines

Manufacturing Process and Quality Control

We have established a full-process traceability system from raw materials to finished products to ensure the stable quality of every Type F Spring Hanger:

▶  Raw Material Control: All steel is sourced from leading steel mills such as Baosteel and Angang. Each batch of materials is accompanied by the original material certificate and undergoes spectral analysis verification.

▶  Spring Manufacturing: Coiled using German imported CNC spring machines and subjected to three heat treatment processes to completely eliminate internal stress.

▶  Welding Process: Adopts carbon dioxide gas shielded welding. All welds undergo 100% visual inspection and sampling non-destructive testing.

▶  Surface Treatment: Three processes of sandblasting derusting → epoxy zinc-rich primer → polyurethane topcoat, with total coating thickness ≥120μm.

▶  Finished Product Inspection: Each product undergoes full-stroke load testing, and complete quality certification documents are issued.

Supporting Services and Delivery Guarantee

▶  Fast Delivery: Standard models are in stock and can be shipped within 72 hours.

▶  Selection Support: Free pipeline stress analysis and support/hanger selection calculation are provided.

▶  Customization Service: Connection dimensions and surface treatment methods can be adjusted according to customer requirements.

▶  On-Site Service: Professional engineers are dispatched to guide installation and commissioning.

▶  Warranty Service: 12-month warranty period with free repair or replacement of defective products during the warranty period.
