This series of clamps is a breakthrough in clamping technology, and the advantages are clear at a glance Bolt head superimposed disc spring design. Has dynamic adjustment characteristics.360 degree compensation for hose shrinkage. Automatic tightening in a wide temperature range increases sealing reliability.Also suitable for thermoplastic hoses. Also has the function of standard clamps. · Four-point riveting design, more firm, so that its destruction torque can reach more than ≧25N.m · Disc spring group pad adopts super hard SS301 material, high corrosion resistance, in the gasket compression test (fixed 8N.m value) for the test of five groups of spring gasket groups, the rebound amount is maintained at more than 99%. · The screw is made of SS410 material, which has higher hardness and good toughness than austenitic stainless steel · The lining helps protect consistent seal pressure · Steel belt, mouth guard, base, end cover, all made of SS304 material, · It has the characteristics of excellent stainless corrosion resistance and good intergranular corrosion resistance, and high toughness
