SSI 402 Anti-VOC Packing


SSI 402 Anti-VOC (Volatile Organic Compound) Packing, 휘발성 유기화합물 억제 패킹
Characteristic

Packing of graphite sheet with compression molding. It can be used from low temperature to high temperature without damaging the reciprocating and rotating shafts due to the self-lubricating of graphite itself, and it is easy to seal and maintain.
그라파이트 시트를 일정한 치수로 압축성형 가공한 패킹. 흑연 자체의 자기윤활성으로 왕복 및 회전축에 손상을 주지 않고 저온에서 고온까지 사용가능하며 밀봉작용과 보수유지가 간단하다.
 
Application

Steam, water, gases, heat medium, oil, hydrocarbon, organic solvents, volatile organic compounds, LNG, extremely low temperature fluids.
 
Composition

Anti0VOC Packing is composed as shown in the figure. The intermediate stage composed of several low density graphite is a stress relieving property and it is economical because it can be used semi-permanently due to various changes and thermal hardening phenomenon. By using Graphite & Inconel wire at TOP & BOTTOM, it guarantees excellent sealing at high temperature and high pressure. Packing ring plays a role to ensure compression by uniformly distributing compression force applied to Anti-VOC Packing.
 
 
API 622

This API Standard specifies the requirements for comparative testing of valve stem packing for process applications where fugitive emissions are a consideration. High temperature packing(s) shall be suitable for use at service temperatures –29°C to 538°C (–20 °F to 1000 °F) and temperature limited packing(s), suitable for manufacturer specified temperature range. Factors affecting fugitive emissions performance that are considered by this Standard include temperature, pressure, thermal cycling, mechanical cycling and corrosion.

RING JOINT GASKET

Characteristic Ring joint gaskets are high temperature, high pressure gaskets largely used in offshore and onshore petrochemical applications. They are precision-engineered components designed to be used in conjunction with precision machined flanges. All our Ring joints are manufactured according to ASME B16.20 and API 6A. ▣ Maximum Hardness for Ring Gaskets NOTES : (1) May be low-carbon steel, not to exceed maximum hardness of 90 Brinell-56 Rockwell “B”. (2) Other CRAs (2-1) Ring gaskets material shall conform to the manufacturer’s written specification. (2-2) Hardness shall meet manufacturer’s written specification.   ▣ Materials   General. Ring-joint gasket materials, some of which are listed in Table 1, shall be selected by the user based on suitability for the service conditions. It is recommended that ring-joint gaskets be of a lesser hardness than that of the mating flanges. Hardness. Ring-joint gaskets of materials listed in Table 1 sh...

SSI 817 Lens Ring Joint Gasket

SSI 817 Lens Ring Joint Gasket   Lens Gaskets are reliable gaskets for high-pressure applications. They are re-usable as the sealing effect is throught about almost entirely by elastic deformation of the gasket surface.
