HelicoFlex series leak rate

HelicoFlex series leak rate

Introducing the selection criteria for the HELICOFLEX(R) HN HelicoFlex series!

We would like to introduce the design standards for our HELICOFLEX(R) HN HelicoFlex series. Designed to meet two different leakage rates. Seal selection according to various applications (gas seals, liquid seals, toxicity, contamination, etc.) must be done before the detailed design of equipment and devices is completed. Insufficient bolt load will prevent even the best metal seals from meeting performance standards. We offer free bolt load calculations before estimates, so please feel free to contact us. 【Features】 ■ Leakage rate at a differential pressure of 1 bar is "bubble-tight" at 1×10^-5 Pa·m³/sec (10^-4 atm·cm³·sec) or below. ■ Leakage rate at a differential pressure of 1 bar is "helium-tight" at 1×10^-12 Pa·m³/sec (10^-9 atm·cm³·sec) or below. The quality of the installation side is crucial. (Seal performance depends not only on the seal itself but also on the material of the installation side, surface finish of contact surfaces, seal compression degree, pressure, temperature, etc. Additionally, it varies with seal shape.) *For more details, please refer to the PDF document or feel free to contact us.

Compression and restoration characteristics: Spring-loaded C-ring Heliflex series

Compression and restoration characteristics: Spring-loaded C-ring Heliflex series

Introducing the compression and recovery characteristics of the HELICOFLEX® series!

We would like to introduce the compression and recovery characteristics of our HELICOFLEX® series. The compression recovery of the HELICOFLEX series features a gently flattening compression curve. The recovery curve takes a different shape than the compression curve. This is the result of two permanent deformations (the elastic deformation of the spring and the plastic deformation of the outer casing). Each value is determined by the allowable leakage amount and the selection of materials. We have included a diagram with detailed information in the catalog, so please feel free to download and take a look. *For more details, please refer to the PDF materials or feel free to contact us.

Spring-loaded C-ring metal seal "HelicoFlex Beta HNR"

Spring-loaded C-ring metal seal "HelicoFlex Beta HNR"

Reduce the Y of the HelicoFlex! It maintains functionality even under positive pressure and high temperatures!

The spring of the "HelicoFlex Beta HNR" has been specially processed around its entire circumference to distribute elasticity more appropriately to the metal casing. When compared to the standard HelicoFlex seal, the design tightening pressure (Y2 value) is theoretically reduced by about 30%. As a result, there are more cases where metal touch can be achieved without scratching the flange groove. For more details, please contact us. 【Features】 ■ Special processing applied around the entire circumference ■ Even lower design tightening pressure than before ■ Maintains functionality even under positive pressure and high temperatures *For more information, please refer to the PDF document or feel free to contact us.

"Selection of Metal Seals" <Materials Being Presented>

"Selection of Metal Seals" <Materials Being Presented>

A high-performance seal manufacturer introduces important points for selecting metal seals such as spring-loaded C-rings.

A high-performance seal manufacturer of seal products such as spring-loaded C-rings, metal seals HELICOFLEXⓇ, and metal hollow O-rings introduces important points for making metal seals functional, as well as key considerations for designers. The selection of metal seals is crucially dependent on the design of the corresponding flanges. The materials of the flanges and bolts, the tightening load (minimum required bolt load during tightening), pressure, temperature, and the method of bolt fastening are all related to the occurrence of insufficient compression in metal seals. ★This document can be viewed immediately by clicking the download button. 【Contents (partial)】 ■ How to make metal seals functional? ■ Seal selection based on allowable leakage rate ■ Compression and recovery of metal seals ■ Bolt load and other factors *For more details, please download the PDF or feel free to contact us.

Metal seal adoption case: Chemical substance canister for semiconductor manufacturing

Metal seal adoption case: Chemical substance canister for semiconductor manufacturing

Metal seal for canisters. Good news for substances that cannot use resin or elastomer seal materials! By adopting metal seals, helium leak tightness has been achieved.

We would like to introduce a case where our "HELICOFLEX Delta Seal" was adopted for seals used in canisters by a chemical company. The specifications for the chemical company's canister seals required reliability to achieve helium leak tightness under both vacuum and positive pressure, as well as excellent durability, which ruled out the use of resin or elastomer materials. After adoption, helium leak tightness was achieved, and the design tightening pressure was lower than usual, resulting in reduced bolt load and a decrease in the number of bolts for the canister cover, which has limited space. 【Case Overview】 ■ Challenge - Desire to repeatedly transport chemicals with helium leak tightness ■ Results - Achieved helium leak tightness - Reduced bolt load due to lower design tightening pressure, leading to a decrease in the number of bolts for the canister cover - Also serves as a solution for PFAS measures *For more details, please refer to the PDF document or feel free to contact us.
