SMLSCO Production Process
Our cast pipe fittings are produced using precision casting (sol silica) technology to achieve excellent dimensional accuracy and surface finish. The process begins with the creation of a wax mold, which is then coated with multiple layers of refractory material to form a ceramic shell. The shell is then heated, causing the wax to melt and flow out. Next, molten stainless steel is poured into the hollow shell. After the steel cools and solidifies, the shell is broken off to obtain a high-precision pipe fitting blank. The blank is then machined, tapped, and other processes to produce the final product.
What are the Types of Cast Plug?
Casting plugs are used to safely block unused internal threaded ports on pipe fittings or pipelines. The most common type is the hexagonal head plug (Hex Plug), with its hexagonal head design facilitating installation and removal using standard wrenches, making it easy to operate. In addition, we also offer other types of plugs such as square head (Square Head) and round head (Round Head) plugs to meet different customers' tool usage habits or specific installation space requirements.
Introduction to Thread Types
Threaded pipe fittings primarily follow two major international thread systems: NPT and BSP. The thread angle of NPT (American Standard Pipe Taper Thread) is 60°, relying on the thread's own taper (1:16) for sealing. The thread angle of BSP (British Standard Pipe Thread) is 55°, which is divided into taper threads (BSPT) for sealing and parallel threads (BSPP). This pipe plug adopts NPT threads, which are the most common connection form in North America and the general industrial field.
CF8M/316 Material Properties
The use of CF8M/316 stainless steel ensures excellent durability and corrosion resistance of the pipe plug. Compared to 304 grade, 316 material performs better in resisting chloride and general industrial corrosion due to its molybdenum content. This is particularly important for the pipe plug, as it effectively prevents the threaded part from getting stuck or failing due to corrosion, ensuring long-term sealing reliability and enabling smooth disassembly during future maintenance or system changes.
