Product advantages

Double ball rubber joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and climate resistance. It has high internal density, can bear high pressure and has good elastic deformation effect. The double sphere has more compensation than the single sphere. The product is made by Luoying company with new technology of air blowing die, which is composed of sphere composed of inner rubber layer, reinforced layer, middle rubber layer and outer rubber layer and loose sleeve forging low carbon steel flange. It has the characteristics of high pressure resistance, good elasticity, large displacement, good vibration absorption and noise reduction effect, and convenient installation. It can be widely used in water supply and drainage, HVAC, fire protection, compressor, papermaking, pharmaceutical, ship, water pump, fan and other piping systems.

The double ball rubber joint is composed of fabric reinforced rubber parts and loose metal flange, which is used for vibration reduction and noise reduction and displacement compensation of pipeline. It is a kind of pipe joint with high elasticity, high air tightness, medium resistance and climate resistance. Luo Ying strictly in accordance with international standards and raw material quality requirements, put an end to the phenomenon of shoddy work. The standard means that the raw materials of the product need not only new materials, but also grade ~ new materials.

Product features

KST double ball rubber joint product installation instructions:

1. Double ball rubber joint must be kept in natural state during pipeline construction, and installation beyond displacement limit is strictly prohibited.

2. When the pipeline medium is acid and alkali resistant, oil resistant, high temperature and other special materials, the joint with a gear higher than the pipeline working pressure should be selected.

3. When the rubber joint is installed on the ground, in the air or vertically, the actual working axial displacement pressure of the rubber joint is less than the support force of the pipeline. Otherwise, the anti pulling device should be installed to prevent the product from losing stability during operation.

4. The flange connecting rubber joint shall be valve flange or flange conforming to GB / t9115.1-2000.

5. The pipeline must have fixed support or fixed bracket, and the force of the fixed bracket must be greater than the axial force. During vertical installation and overhead installation, both ends of the product shall be installed with corresponding fixed support and stress support to prevent pulling off after working under pressure.

6. Installation should be far away from heat sources, do not use media that do not meet the requirements of this product.

7. After the rubber flexible joint is subjected to pressure for the first time (such as installation and pressure test) or before it is put into use again after long-term shutdown, the bolts shall be re pressurized and tightened before putting into operation.

8. When the pipeline displacement is greater than or equal to the large compensation of the joint, the number of joints should be increased to parallel the displacement. It is strictly forbidden to make the joint in the limit deflection displacement and deviation state in order to adjust the pipeline out of tolerance, let alone exceed the limit (expansion, displacement, deflection, etc.). See the table below for the specific installation data.

9. For high-rise water supply or suspended water supply, the pipeline shall be fixed on the hanger and bracket, and the joint shall not bear the weight and axial force of the pipe itself, otherwise the joint shall be equipped with anti pulling device (the bearing force must be greater than the axial force of the pipeline).

10. When installing the rubber joint, the screw of the bolt should extend to the outside of the joint, and the bolt of each flange end face should be repeatedly and evenly tightened according to the method of diagonal pressure to prevent pressure deviation.

KST double ball rubber joint plays an important role in Baosteel Zhanjiang iron and steel base

On November 29, the 2250 mm hot rolling project of Zhanjiang iron and steel base of Baosteel was successfully put into operation. The production line was rolled into coils at one time with good coil shape.
The 2250mm Hot rolling project of Zhanjiang iron and Steel Co., Ltd. is one of the core projects of Zhanjiang iron and Steel Co., Ltd. Shanghai Luoying, as the main supplier of KST double ball rubber joint, plays an important role in Baosteel Zhanjiang steel base. After the installation of the double pipe joint, the rubber joint is more stable in the pipeline.
As a major design unit of the project, mcc-saidi overcame the adverse factors such as severe climate conditions and complex geological and hydrological conditions in Zhanjiang area, adopted comprehensive measures for soft silt foundation treatment with strong pertinence, and the anti typhoon design withstood the inspection of rainbow typhoon, effectively ensuring the engineering safety and production safety. This project is in the lead in terms of steel structure and steel consumption per ton, which can meet the requirements of steel structure and steel consumption in China.
The project adopts the pulse combustion and intelligent control technology of walking beam slab reheating furnace independently developed by SYMC, highlighting the characteristics of high-end hot rolling projects such as energy saving, ~, and high efficiency; it adopts the high-strength hot-rolled strip temper mill technology independently developed by SYMC, with large strip running speed of 400 m / min, processing strip with large tensile strength of 1000 MPa, and coiling tension reaching the domestic similar machine The group is at a very high level.
Shanghai Luoying has been specialized in the production of double ball rubber joint for 30 years. We have always been guided by the interests of users, won customers with quality, occupied the market with integrity, and made continuous efforts to build a first-class rubber joint brand in China.
