API Coupling
As we know steel pipe coupling is a short pipe or tube that with threads on both ends, used to connect pipelines. So It is a kind of pipe fittings that with threaded connection, the advantage is easy for pipeline maintenance or to replace the broken pipe.
API Coupling refers to the steel couplings that used in connecting casing pipe and tubing. Also known by OCTG coupling, it is usually manufactured in seamless type, material grade same with the pipe body (API 5CT K55/J55, N80, L80, P110 etc), same PSL or providing higher grades than requested. Same heat treatment also applicable, except there is an special requirements.

Main Features of PU+Mineral Wool Sandwich Panel Machine:
Panel from the continuous sandwich panel production line is a composite structure consisting of two external facings and an insulating core. The core can be flexible with Polyurethane, Mineral Wool, Glass Wool, PIR, Phenolic or EPS. Various profiles are available according to customer's requirement with pre-painted steel sheets, PVC sheets, Aluminum paper or other similar supports.
The continuous sandwich panel production line has a large scale production capacity. It allows a uniform distribution of the reactive mixture, a homogeneous density, suitable physical and mechanical characteristics.
Roof panels, wall panels and door panels are made mainly of metal section support and polyurethane insulating mass.
The capacity of the continuous line is 3-7m/min, length of the production line is 100m, the size of the final panel is 3-18m long, 900-1200mm wide, 20-150mm thick, the valid length of double belt conveyor is 24m, the total power is 300KW.
