Sleeve Type Metal Expansion Joint-Sleeve Type Metal Expansion Joint

Overview

Sleeve type compensator is also called tubular expansion joints,Is the hot fluid pipeline compensator,
mainly used for line pipe and auxiliary axial thermal expansion displacement after absorption compensation,
is a kind of directly installed in any transport noncorrosive unidirectional and multidirectional of fluid pipeline
compensator.Sleeve type compensator. Widely used in the pipeline of urban heating, metallurgy, mining, power
generation, petrochemical and construction industries.

General sleeve compensator

It’s designed according to CJ/T3016.2. It’s mainly used in overhead pipeline axial compensation and also can used in direct-burried pipeline, absorption temperature difference cause by pipeline axialexpansiongWidely used in the pipeline of urban heating, metallurgy, mining,power generation, petrochemical and construction industries.

Features

Structural characteristic:

Mainly include the sleeve tube (core), shell, sealing materials, etc,to compensate the axial expansion of the pipe and

the axial rotation at any angle.With the characteristics of small volume , large amount of compensation and suitable

for hot water, steam, oil medium,move by sliding between the sliding sleeve and outside sleeve, Finally achieving the

compensation of the thermal expansion.

Installation method

General sleeve

1, sleeve type compensator in the installation shall be properly kept, prevent weathered and dust pollution.

2, when installation, should check the compensator model specification and design are consistent, the product surface

should be no bruising, pit, and the serious corrosion defect affecting the quality of products, etc.

3, the onetime compensator is consistent with the samples, the total length of finished products don't have to stretch or

compression, if there is new on the telescopic duct installation line, should again after alignment for installation

4, for twoway thrust compensator, a diagram must be in the note to the flow direction of medium of the installation, when

the medium is steam, lest compensator to form gas plug. In order to guarantee the compensation amount of the

compensator two directions are equal, when the design must have the two-way compensator is arranged between two

fixed point.

5, and the phase compensator on both ends of the welding section must break processing, water pressure test in

accordance with requirements after welding (pressure test on both ends of the bolt should be tighten packing chamber)

without any leakage. Run 24 hours later, the packing room must be tight on both ends of the bolt again.

6, in order to guarantee pipeline without lateral displacement, only along the axial expansion, the expansion pipe side

guide bracket. When two Zha compensator are axial displacement, then both sides should guide bracket, ensure that

the axial displacement of compensator eccentricity plus or minus (+ -) not more than once.

7, the compensator can be the same as the pipe insulation waterproof structure, but can not exert blind on the expansion

period .
