This elbow adopts BSP (British Standard Pipe Thread) connection, featuring a 55° thread angle design that can be connected via tapered threads (BSPT) or parallel threads (BSPP). Threaded connections eliminate the need for on-site welding, making installation and disassembly highly convenient. It is a cost-effective and flexible connection solution in low-pressure piping systems.

The use of CF8M/316 stainless steel provides superior corrosion protection for low-pressure pipelines. Compared to 304 material, 316 with molybdenum addition offers enhanced resistance to chlorides and various industrial chemical media. Choosing 316 Stainless Steel Elbow ensures lower long-term maintenance costs and higher operational safety for systems with demanding service life requirements.

Our casting pipe fittings are produced using precision casting (sol silicate) technology to achieve excellent dimensional accuracy and surface finish. The process involves creating a wax mold, coating it with refractory material to form a ceramic shell, then pouring molten stainless steel into the hollow shell. After cooling, the shell is removed to reveal a high-precision pipe fitting blank that undergoes machining, threading, and finishing processes.

Class 150-pound 316 stainless steel elbows are fundamental components in various low-pressure industrial piping systems. They are widely used in applications requiring higher corrosion resistance, including chemical industry auxiliary pipelines, coastal water supply/drainage systems, and other corrosive fluid environments. The 1/2-inch small-diameter design makes them particularly suitable for connecting instrument pipelines, sampling points, and small branch lines.

FAQ:

Q1: Is this 1/2 "316 stainless steel elbow suitable for use in seawater or coastal environments?

A1: Very suitable. 316 (CF8M) material has excellent pitting corrosion resistance to chloride ions due to the presence of molybdenum element. Compared to 304 material, it can withstand long-term erosion from seawater salt spray and marine atmosphere, making it an ideal choice for coastal building water supply and ship auxiliary pipelines.

Q2: How does the silica sol precision casting process used by SMLSCO improve product quality?

A2: Compared to ordinary sand casting, our all silica sol process can significantly improve the dimensional accuracy and surface smoothness of elbows. This means that the inner wall of the product is smoother, the fluid resistance is smaller, and the thread profile is more precise, which can effectively improve the overall airtightness and aesthetics of the pipeline system.

Q3: What sealing material is recommended for installing BSP threaded elbows?

A3: To ensure zero leakage of Class 150 low-pressure systems, especially when connecting BSP cylindrical pipe threads, we recommend using high-quality polytetrafluoroethylene (PTFE) tape or professional pipe thread sealant. This can fill the thread gap and provide a durable and reliable physical seal.

Q4: How do you ensure that the material of this batch of elbows meets the 316 standard?

A4: SMLSCO regards quality as life. We conduct strict spectral analysis (PMI testing) on our products before leaving the factory to ensure that the molybdenum content meets the standard and the chemical composition fully complies with ASTM A351 standard. We provide you with genuine and reliable material certification to prevent inferior products from being sold as good.
