Texas, US-based PT&P has custom designed 78 figure 2000 heavy-duty pipe saddles for two 24in insulated ductile iron pipelines. The two pipelines are routed beneath a 650ft bridge crossing over a river in upper New York State. The insulation is 3in thick with high density polyethylene jacketing. Axial movements, due to expansion, can approach 3in. In order for the jacketing to avoid being damaged when displacements occur, the saddles have been lined with polished stainless steel.
