Schedule 10 butt weld fittings connect with low-pressure (100-299 psi) pipe. Butt weld (BW) fittings form pipe joints with strength, fatigue, corrosion resistance, and temperature compliance. These beveled fittings are welded to the ends of same thickness Schedule 10 stainless steel unthreaded pipe. Schedule 10 has a thinner wall thickness than Schedule 40 or 80 pipe. Type 304 stainless steel, a chromium-nickel material, resists corrosion caused by water, heat, saltwater, acids, minerals, and peaty soils. Type 316 stainless steel has a higher nickel content than 304 stainless, plus molybdenum, for even greater corrosion resistance.

Schedule 40 butt weld fittings connect with medium-pressure (300-999 psi) pipe. Butt weld (BW) fittings form pipe joints with strength, fatigue, corrosion resistance, and temperature compliance. These beveled fittings are welded to the ends of same thickness Schedule 40 stainless steel unthreaded pipe. Standard weight Schedule 40 has a thicker wall thickness than Schedule 10 pipe, but isn't as strong as Schedule 80. Type 304 stainless steel, a chromium-nickel material, resists corrosion caused by water, heat, saltwater, acids, minerals, and peaty soils. Type 316 stainless steel has a higher nickel content than 304 stainless, plus molybdenum, for even greater corrosion resistance.

Schedule 40 butt weld swage nipples connect with medium-pressure (300-999 psi) pipe. Butt weld (BW) swage nipples are similar to butt weld reducers and are used to change the direction of flow in smaller diameter pipe systems. Concentric and eccentric swage nipples are available with various ends. The most common end types are beveled (BBE), plain (BPE), or threaded (TBE). Standard weight Schedule 40 has a thicker wall thickness than Schedule 10 pipe, but isn't as strong as Schedule 80. Type 304 stainless steel, a chromium-nickel material, resists corrosion caused by water, heat, saltwater, acids, minerals, and peaty soils. Type 316 stainless steel has a higher nickel content than 304 stainless, plus molybdenum, for even greater corrosion resistance.

Schedule 80 butt weld swage nipples connect with high-pressure (1000-3000 psi) pipe. Butt weld (BW) swage nipples are similar to butt weld reducers and are used to change the direction of flow in smaller diameter pipe systems. Concentric and eccentric swage nipples are available with various ends. The most common end types are beveled (BBE), plain (BPE), or threaded (TBE). Schedule 80 pipe is stronger than Schedule 10 or Schedule 40 pipe. Type 304 stainless steel, a chromium-nickel material, resists corrosion caused by water, heat, saltwater, acids, minerals, and peaty soils. Type 316 stainless steel has a higher nickel content than 304 stainless, plus molybdenum, for even greater corrosion resistance.
