Heat treatment requirements: According to customer requirements, we will normalize, normalize and temper or quench and temper the pipe fittings. The tempering temperature shall not be lower than 620°C to ensure that the material obtains the best mechanical properties and microstructure.

Mechanical property test: If the size of the pipe fitting allows, we will destroy the finished product for mechanical property test. If this is not allowed, samples need to be taken from the extension section of the pipe for testing to ensure that the quality of the product meets the standard requirements.

Sulfur resistance performance requirements: According to the requirements, the sulfur content of seamless pipe fittings shall not exceed 0.010%, welded pipe fittings shall not exceed 0.003%, and forged pipe fittings shall not exceed 0.020%. Excessive sulfur content may lead to brittleness of the material and affect the service life of the product.

Hardness limit: For sulfur-resistant pipe fittings, the hardness must not exceed 250 HV10 to ensure the stability and durability of the product during use.

HIC test: If welded pipe fittings have sulfur resistance requirements, HIC testing is required to evaluate their corrosion resistance in sulfur-containing environments.

Impact test conditions: According to customer requirements, the impact test is conducted at a temperature of -20°C, and the acceptance standard is 27J/20J to ensure that the product has good toughness in low temperature environments.

Provide 3.1 certificate: We will provide a 3.1 certificate that meets the requirements as a guarantee of product quality.

Haihao Group is known for its excellent quality management and strict production processes, and we are committed to providing customers with the highest quality products and services. Whether it is strict requirements on material composition or comprehensive inspection of product performance, we always aim at customer satisfaction and strive to create greater value for our customers.

Are you curious about the distinctions between Series A and Series B within the ASME B16 47 standard for flanges? Let’s delve into the details of the difference between ASME B16.47 Series A and Series B flange.

In essence, when it comes to the same dimensions and pressure ratings, Series A flanges are thicker, heavier, and stronger compared to Series B flanges. Consequently, from a commercial standpoint, Series A flanges are generally pricier than their Series B counterparts.

ASME B16.47 A105 Class 900 Series A welding neck flanges

ASME B16.47 A105 Class 900 Series A welding neck flanges

When examining flanges of identical pressure ratings and nominal diameters, the disparities become apparent. Series A exudes a robust and vigorous aura, while Series B emanates a more delicate and compact vibe.

Furthermore, Series B flanges require more but smaller fasteners (bolts and nuts) than Series A flanges, and the bolt circle diameter is smaller in Series B compared to Series A.

Both Series A and Series B define raised face (RF) weld neck flanges and blind flanges; however, only Series A encompasses ring joint (RJ) flanges ranging from Class 300 to Class 900.

The dimensions of the fittings paired with Series A and Series B are entirely distinct. For instance, the outer diameter of a DN650-Class150 fitting in Series A is 660.4mm, whereas in Series B, it is 661.9mm.

Of particular note is that the outer diameter of the weld ends (fitting outer diameter) in Series A is independent of the pressure rating, whereas in Series B, the outer diameter of the flange weld ends varies for different pressure ratings. For instance, for a DN800 Series B flange, the outer diameter for Class 150 is 814.3mm, for Class 300 it is 819.2mm, and for Class 600/900 it is 812.8mm.

Take, for instance, DN1500 fittings: the outer diameter for Class 150 is 1527mm, for Class 300 the fitting outer diameter is 1557.3mm, resulting in a difference of 30mm. This detail is crucial as many have encountered issues due to inaccuracies in the outer diameter of DN fittings, leading to the scrapping of matching fittings.

In conclusion, understanding the disparities between ASME B16.47 Series A and Series B flanges is imperative for accurate selection and application in various industrial contexts.
