PRODUCTS DETAIL SHOW

1. Face
Can be raised face(RF), full face(FF), Ring joint(RTJ) , Groove, Tongue, or customized.

2.Bevel end as per ANSI B16.25

3.CNC fine finished.
Face finish: The finish on the face of flange is measured as an Arithmetical Average Roughness Height(AARH). The finish is determined by the standard used. For example, ANSI B16.5 specifies face finishes within a range 125AARH-500AARH(3.2Ra to 12.5Ra). Other finishes are available on requst, for example 1.6 Ra max,1.6/3.2 Ra, 3.2/6.3Ra or 6.3/12.5Ra. The range 3.2/6.3Ra is most common.

FAQ

1. What are the different types of stainless steel pipe fittings?
Answer: Stainless steel pipe fittings include butt welding pipe fittings, socket welding pipe fittings, threaded pipe fittings, flanges, valves and other types.

2. What is the difference between stainless steel 304 and 316 stainless steel pipe fittings?
A: 304 stainless steel is suitable for most applications and has excellent corrosion resistance. 316 stainless steel, on the other hand, has better corrosion resistance in highly corrosive environments and is better suited for marine and chemical applications.

3. What are the benefits of using forged butt welded pipe fittings?
A: Forged butt weld fittings provide enhanced strength, reliability, and leak-free connections. They offer excellent impact resistance and are preferred for high pressure and high temperature applications.

4. What is a butt welding flange?
Answer: A butt welding flange is a pipe flange that has a long tapered hub and is welded to the pipe. It provides a smooth transition from pipe to flange with excellent strength and integrity.

5. Which stainless steel grade is commonly used for pipe fittings?
A: Stainless steel grades 304, 316, 304L, 316L and 317 are commonly used in pipe fittings due to their excellent corrosion resistance, durability and versatility.

6. Can stainless steel pipe fittings be used in high temperature applications?
Answer: Yes, stainless steel fittings are suitable for high temperature applications. However, the grade of stainless steel used should be carefully selected based on the specific temperature requirements of the application.

7. Are stainless steel pipe fittings suitable for the food and beverage industry?
Answer: Yes, stainless steel pipe fittings are widely used in the food and beverage industry because of their hygiene, corrosion resistance, and easy maintenance.

8. What is the difference between socket welding fittings and butt welding fittings?
Answer: Socket welded pipe fittings insert the pipe into the socket and then perform fillet welding to connect the pipe. Butt weld fittings, on the other hand, require the ends of the pipe to be beveled and then welded.

9. Can stainless steel pipe fittings be recycled?
A: Yes, stainless steel pipe fittings are highly recyclable. Stainless steel is a sustainable material that can be recycled and reused without losing its properties or quality.

10. What are the advantages of using stainless steel pipe fittings compared with other materials?
A: Stainless steel pipe fittings offer many advantages, such as excellent corrosion resistance, high strength, durability and hygienic properties. They are low maintenance, have a long lifespan and have a clean and beautiful appearance.
