Low-performance high-efficiency sealing gasket HLelaG series

The low-stress and high-efficiency sealing gasket HLelaG is a patented new product of Hengli Sealing. It has an innovative sealing body material and structure. The inner and outer sides of the sealing element are multi-turn special-shaped reinforced alloy belts. The special-shaped reinforced alloy belt plays a role in the sealing body. Protection and radial reinforcement. The main body of the seal is made of HLela high-elasticity, high-temperature and corrosion-resistant special flexible graphite tape wound and moulded.

Detail
Parameters

• There are three types of HLelaG gasket structure: Type I, II and III

 

Type I
No inner ring and outer ringFor birch groove surface (TG) flange

Type II
Inner ring onlyFor concave and convex (MFM) flanges

Type III
There are inner ring and outer ring
For full-face FF or raised face RF flanges

 

 

• Significant features of low-stress high-efficiency sealing gasket (HLelaG):

 

HLelaG can get better elastic deformation with lower pre-tightening stress: t4.5mmHLelaG can get an elastic deformation of 0.3mm under the condition of 35Mpa locking loading stress, which means that the installation is easier, and it also shows that HLelaG has enough additions Preload compression margin, so HLLaG has a longer service life.

The elastic deformation capacity of HLelaG is better than that of metal corrugated gaskets and metal spiral wound gaskets: Under the same test conditions, the elastic deformation rate (compression rate * resilience rate) of HLelaG far exceeds that of flexible graphite metal spiral wound gaskets specified in GB4622.3 The elastic deformation rate (3.06% at 70Mpa is qualified) and the elastic deformation rate of flexible graphite metal corrugated gaskets specified in GB19066.3 (3.75% at 45Mpa is qualified). Excellent elastic deformation ability ensures excellent sealing performance when working conditions change.

The sealing performance of HLelaG is better than flexible graphite metal spiral wound gasket and flexible graphite metal corrugated composite gasket.

The HLelag sealing body is a flexible body, which can better adapt to the condition of the flange sealing surface and the flange locking conditions, and the installation conditions are adaptable.

The main body of the HLelag seal is a molded and flexible whole, which will not cause the gasket to collapse and the surface non-metallic composite layer to fall off.

There are several turns of elastic alloy belt on the inner diameter side and outer diameter side of the HLelag sealing body, which protects the HLela high-elasticity, high-temperature and corrosion-resistant special flexible graphite sealing belt to ensure the sealing safety when the medium pressure increases sharply and the medium is under high pressure.

 

 

• Scope of application:

    

Where the outer diameter of the gasket is 800mm, such as pipeline flanges and equipment flanges within 24' of the American standard or DN600 of the European standard.

Applicable temperature -200°C ~ 650°C (oxidizing medium ≤ 450°C); applicable pressure ≤ 25Mpa.

Applicable medium: related to the selected metal material.

It still has excellent sealing performance in occasions where temperature and pressure are cycled, or where equipment or pipelines are shaken.
