These range in cost and difficulty from relaying the line to clamping. Clamping is obviously the quickest and least expensive method. However, there are not clear guidelines as to where clamp repair is applicable.\u003c\/p\u003e\n\n\u003cp\u003eThe object of this project is to explore the limits of a dent which may be sealed by a clamp. This is to determine whether or not a particular dent can be sealed by the prototype clamp. This work was done with the aid of non-linear finite element analysis of a typical rubber seal using the ABAQUS program. The effect of various pipe ovalities was investigated relative to the clamps ability to provide active circumferential seal pressure. It was shown that initially the clamp circumferential seals gradually built hydrostatic pressure due to gland loading until the rubber traversed the gap distance between the clamp and pipe. Then the contact pressure increased at a rapid linear rate as the glands were tightened further.\u003c\/p\u003e","brand":"PRCI Store","offers":[{"title":"Default Title","offer_id":44367625683022,"sku":"15065","price":395.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/prci-store.myshopify.com\/products\/l51701-determination-of-clamp-repairable-leaks-1","provider":"PRCI Store","version":"1.0","type":"link"}
