The plugs block up the unwanted ports in the pipeline and act as a closure. The specification parameters are as follows.
1, diameter: DN15-DN1200
2, wall thickness: SCH5-SCH160
3, standards: ASME B16.11 DIN JIS BS GB/T JB SH HG
Plugs removed from the use in the manifold can also be used in the beer, food, petrochemicals, nuclear power, machinery, medical equipment, fertilizer, shipbuilding, medical equipment, and so on. equipment, fertilizer, shipbuilding, waterproof treatment, pipeline and other places.

Plug manufacturing methods:
1, small plugs: integral molding;
2, large and medium plugs: first splicing and then molding - the most used, the requirements of the standard mainly for it;
3, special plugs: the first splicing and then molding - the most used, the standard requirements mainly for it;
3, special plugs: the first splicing and then molding - the standard requirements mainly for it;
3, extra-large plugs: due to the requirements of transportation and open file and other factors, first split flap molding, and then group welding together.
Splicing weld direction requirements only allow radial and circumferential. Later large plug may cancel this requirement. Splicing distance should be required for more than 3 δ, and not less than 100mm (welding heat-affected zone is a high-stress area, and in the area of the chemical composition will have burned. So avoid the high stress area, the area is related to the thickness.
