L8 Pipe support and hanger connecting piece U-shaped ears, ring ears

Supports and hangers are mainly used for power plant steam and water pipelines or boiler equipment, thermal displacement and equipment during operation. According to the calculation of the force of the pipeline, the spring support and hanger work and thermal displacement requirements are determined by the factory. The spring support and hanger are adjusted according to the design load: that is, the spring is preloaded and the cold load position is set; at the same time, the cold state is marked Theoretical work position.

The spring supports and hangers are adjusted by the manufacturer before leaving the factory. After they are installed on the pipes and equipment, make relevant thread adjustments to disengage the fixed pins. At this time, the actual load of the spring is the cold load required by the design.

2. Model and type

There are four series of variable spring supports and hangers, mainly T1, T2, T3, T4, T5 series designed by Northwest Electric Power Design Institute, TH1, TH2, TH3 series and TD series designed by East China Electric Power Design Institute ( JB/J8130.2-1999) and the VS series designed by the Chemical Design Institute, the basic characteristics of the series are the same, and the bearing capacity is 20daN-21000daN. The main structural forms are suspension type, supporting type and parallel suspension supporting type.

(3) T, TH structure form and model representation method:

The hanger is divided into three types: the middle connecting hanger spring TH 1, the upper and lower connecting hanger spring TH 2, and the bracket spring TH 3 according to the installation form.

TH 1 is divided into three types: A, B, and C; TH 1 A (T1) is a single-ear connection hanger spring; TH 1 B (T2) is a two-ear connection hanger spring; TH 1 C is a threaded connection hanger spring;

These three types of springs are mainly used to hang on steel beams, tube beams, and bottom plates.

TH 2 (T3) is suitable for installation on steel beams; TH 3 (T4) is mainly used for laying on foundations, steel beams, and floor slabs; T5 is a parallel suspension type.

(4) VS, TD structure form and model representation method:

The variable spring supports and hangers are mainly composed of cylindrical spiral springs, displacement indicating plates, shells and elastic nuts.

The variable spring supports and hangers are divided into seven types: A, B, C, D, E, F, and G according to different installation methods.

Type A-upper thread suspension type; Type B-single ear suspension type; Type C-double ear suspension type; Type D-upper adjustment shelving type; Type E- ---Lower adjustment shelving type; F type-support shelving type; G type-parallel suspension type;

Install correctly

1. Choose the middle connection and end connection of the lifting lugs according to the objects to be lifted.
2. The lifting lugs and the connecting piece should be on the same connecting force center.
3. The lifting lugs are not allowed to be twisted or staggered installation.
4. The lifting lugs and connecting pieces are matched with each other.
5. When the lifting lugs are under no load and load, they should not be hit or beaten, and they are not allowed to be disassembled immediately.
6. The safety of the environment shall be fully considered during lifting. Do not lift in an unsafe environment. People must keep a certain distance from the scene during lifting.
7. Strictly abide by the safety rules of hoisting and transportation
