Characteristic

Kammprofile gasket (Serrated metal gasket) is made of cold rolled metal plate, but it has concentric grooves and effective sealing area is minimized so as to increase sealing effect. Flat metal gasket is the most simple and economical type of all metal Gaskets which is made of cold rolled metal plate. Both of these gaskets are extensively used on pipe flanges. Valve Bonnets, covers of pressure vessels at high pressure and temperature.

Performance and technical integrity of the gaskets 신뢰성 검증

Type Acceptance Test

The Type Acceptance Test (TAT) is installed to verify the design, performance and technical integrity of the gaskets and manufacturing plant.

Test Specimens

The dimensions of the test specimens for the different tests were EN 12560-6, Class 300, 4” The dimensions of the flanges in contact with gasket is OD = 154.0mm and ID = 123.8mm. The thickness of the Spiral Wound Gasket is 4.0mm. The thickness of the outer ring was 3.0mm.

Test Equipment

The gasket tests were carried out on the following testing equipment: Below Multifunctional test rigs are TEMES and Fire Safe testing Device.

Test Results

The Kammprofile Gasket passed all test according to Shell Specification MESC SPE 85/300

Hydraulic Test(수압테스트)

The Hydraulic Test is to verify the design, performance and technical integrity of the gaskets and manufacturing plant according to ASME B16.5

Test System

The test system is specified in B16.5 clause 2.6 as follows. 2.6 System Hydrostatic Testing Flanged joints and flanged fittings may be subjected to system hydrostatic tests at a pressure of 1.5 times the 38°C (100°F) rating rounded off to the next higher 1 bar (25 psi) increment. Testing at any higher pressure is ASME B16.5-2009 the responsibility of the user, taking into account the requirements of the applicable code or regulation.

Test Specimens

The dimensions of the test specimens for the different tests were ASME B16.20 , 4” Class 300. The dimensions of the flanges in contact with gasket is OD = 154.0mm and ID = 123.8mm. The thickness of the Spiral Wound Gasket is 4.5mm.

Test Results

The Kammprofile Gasket passed the hydraulic test according to ASME B16.5

High Operating Temperature (HT) Type

The Kammprofile gasket is a seal that can withstand the best loads. P and C types are used for Male & Female and Tongue & Groove type flanges with no centering ring (collar) type. PR, PR1, CR and CR1 types are used for flat face and raised face type flange. Sealing core has uniform sealing on both sealing surfaces and is covered with flexible graphite, PTFE or HT (E-Graphite + Mica) on the surface of serum. This results in high sealing with low seating stress. Samsung Industries' Kammprofile is made from reliable materials and precision machining.

Sizes: Standard sizes are prepared to fit ASME and JIS pipe flanges. Other gasket sizes are also available with EN 12560-6 and EN 1514-6 standard dimensions.
