149 Sleeve Joint is a structural pipe fitting that can be used to build Pipe Railing Systems. Its role is to connect two pipes to increase the length of the transverse railing in Pipe Railing Systems. 149 Sleeve Joint can only be used in straight guardrails or handrails because it is straight. If you need to adjust the angle of the horizontal railing, you can choose to use, 123, 124, 125, and 125H. If you need to make the horizontal railing look more even, you can choose to use 150 internal joints. The manufacture of 149 Sleeve Joint mostly uses malleable steel and ductile iron as raw materials and uses a sand casting process. If it is an aluminum structural pipe fitting, a casting process is required. HULK Metal can provide excellent structural pipe fittings production services.
