AISI 310H Stainless Steel ButtWelded Stub Ends Lap Joints Fitting

The AISI 310H Stainless Steel ButtWelded Stub Ends Lap Joints Fitting is a type of pipe fitting which connects different pipe or tubes sizes. Stub ends refer to short sections of pipe where one end is flared outward for sealing against the larger pipe while lap joints are flanges that are placed over the stub ends and jointed with bolts. The fittings are of AISI 310H stainless steel which is a high-temperature version of 310 grade. The quality and performance of Rexon Pipe Fittings is ensured by its modern production facility, which is equipped with the most updated machinery as well as quality control tools. Rexon Pipe Fittings also offers bespoke solutions, including unique dimensions, shapes and finishes, to address the needs of the clients.

AISI 310H Buttwelded Stainless Steel Stub End Lab Joint Physical Property

The lap joint flange is crafted to be a mirror image of the stub end. It is bored to match the pipe’s outside diameter. The face of a lap joint flange matches that of the stub-end, which is having the same specifications as butt-welded pipe, being equal to AISI 304.

310H Buttwelded Stainless Steel Stub End Lab Joint fitting Chemical Property

Corrosion resistance is another feature of SS buttweld reduce pipe fittings. These are stainless steel types of materials which enhance the quality of chromium content features, and they are resistant to reducing acids and pitting attacks such as chloride solutions.

Frequently Asked Questions

What is the difference between long radius and short radius elbow fittings?

It is the long radius elbow fittings that have a longer curvature, thus giving smoother fl ow and minimized pressure drop. Short radius elbow fittings provide a smaller curvature radius and hence compactness but can lead to higher pressure drops.

What is the maximum pressure rating for stainless steel butt-welded elbow pipe fittings?

However, the maximum pressure rating relies on material grade, fitting size and design. It is always necessary to follow the manufacturer’s specifications and standards of industry for these particular pressure ratings.

Can stainless steel butt-welded elbow pipe fittings be used in high-temperature applications?

The answer is yes because stainless steel butt-welded elbow pipe fittings can resist high temperatures. The temperature specifications, however, may be dependent on the material grade and its use. It is therefore important to take into account the temperature restrictions from the manufacturer and refer back to industry standards.
