A. Mechanical Coupler (MC)

Mechanically coupled joints typically seal on the OD of plain end pipes through the use of gaskets that are loaded mechanically (compressed) to effect the seal. There is no ability to accommodate longitudinal forces in this design. Mechanical coupler are mostly non-thrust resistant.

B. Flanged Joint (FJ)

To enable connection with many types of pipes and to allow for easy assembling and disassembling of process lines, specifications. Special requirements can be met upon request.

Glass Fiber reinforces epoxy flanges are always flat faced and in view of this, matching flanges should also be flat faced. The flanged joint is completed by using a gasket.

Flanged Joint

C. Laminated Joint (LJ)

Generally these joints will only be used for diameters over 400 mm. the joints is consisting of Layers of fiberglass mat and/or tapes impregnated with the preparation of this rigid requires good craftsmanship.

Laminated Joints

D. Adhesive Bonded Joint (CJ)

The advanced strong adhesive bonded joint is a rigid type of joining. The adhesive is a two component epoxy resin system, packed in separate containers. The joint consists of a slightly conical socket end and a cylindrical spigot end.
