    摘要: A containment pipe fitting has an inner member (40; 260), an outer member (42; 262), and a plurality of centralizers (48) positioning the inner member within the outer member. The fitting has at least one connection interface (37; 38; 39; 254; 255) having an internal surface portion (72) of the inner member sized to receive and join a portion of an associated inner/main pipe (31; 32; 33) and an internal surface portion (80) of the outer member sized to receive and join the portion of an associated outer/containment pipe (34; 35; 36). The connection interface further includes an external surface portion of the outer member dimensioned to receive a closure coupling or collar (100; 100′).
