Segmented elbows, also known as gored elbows or gored segmented elbows, are segments joined together by welding or mechanically locking them together. The mechanical method incorporates a machine that forms the ends of the segments (gores) so that one segment fits into the other and then mechanically locks them together.

ONE-LOK™ Series SLDM for Oversized Pipe 1) The SIGMA ONE-LOK™ Series SLDM modified wedge-action mechanical joint restraining gland is suitable for use on pit cast grey iron pipes with “oversized” C and D

segment lock onto the pipe wall. This action causes the primary contact edges to grip the pipe and effectively restrain all classifications of ductile iron pipe.

ONE-LOK SLDE’s unique wedge segment and actuating bolt design allows the two components to interface using a cam action principle, allowing the wedge segments to rock and increase their grip on the pipe wall as thrust on the assembled

Heavy gauge elbows for heavy duty applications. Segmented elbows or gored segmented elbows are available in galvanized, stainless steel, and carbon steel in ALL duct gauges and radii. These are segments that are then joined together by welding or …

When the wedge segment is engaged by the actuating bolt, the primary contact edges of each wedge segment lock onto the pipe wall. This action causes the primary contact edges to grip the pipe and effectively restrain all classifications of ductile iron pipe.

Oct 2, 2020 · Round duct is manufactured with various seam types, the most common being spiral or snap lock. Round duct is used to connect between fittings, accessories and flex duct. Manufactures usually stock standard lengths, but if you have your own spiral machine you can fabricate any length.

Dec 5, 2024 · When the wedge segment is engaged by the actuating bolt, the primary contact edges of each wedge segment lock securely onto the pipe wall. This action causes the primary contact edges to grip the pipe and effectively restrain the assembly. Suitable for use on ductile iron, PVC, steel, and HDPE.

Jun 20, 2024 · SIGMA is pleased to announce the wide availability of the 24” Split Gland SSLD ONE-LOK with Re-rounding. This patented feature, previously offered on 30”-64” SLDEs, has generated such market demand that we developed an additional size.

Implements a series of individually activated wedges into the mechanical joint follower gland, when the wedge segment is engaged by the actuating bolt, the primary contact edges of each wedge segment lock onto the pipe wall, this action causes the primary contact edges to grip the pipe and effectively restrain all classifications of ductile ...
