Customer Reviews
The delivery time is very timely. Compared with other products I bought from Chinese sellers, you are a manufacturer that can really deliver and ship in accordance with the terms of the contract.

—— Regan Bell

Not bad, the quality is good, and the speed is fast!

—— Shafeeq Shukoor

The product quality is good, but your price will be higher than the price I got from other places, but it is within the acceptable range.

—— Morteza

The goods are received. Yours are very close to the products I imported from Germany, but the prices are much lower.

—— Marty Higdon

Our customers are very demanding and picky about quality, but after seeing your products, they hardly believe that they were imported from China, which is amazing.

—— Uwe Nolte

This is my first time importing products from China. Before that, I dared not try them easily, but I was very satisfied after receiving your goods.

—— Njabulo Mabaso

Thank you for your full assistance in the delivery process, so that we can receive the goods quickly and save a lot of time.

—— Luzuko Ntsomi

I found your company through the introduction of a friend. Obviously your product proves your strength.

—— Neda

Very professional, good reputation and prompt delivery.

—— Tony Malaka

I believe that when I next buy your products, I can save a test fee.

A182 F51 is the grade of duplex stainless steel forgings

The corresponding pipe and plate grades are S31803. In the standards of pipe SA312 and plate SA240, the hardness of S31803 is less than HB293. The so-called duplex stainless steel refers to the ferrite phase and austenite phase in their solid solution structure account for about half, generally less The content of dual-phase steel also needs to reach 30%.

In the case of low C content, the Cr content is 18%~28% and the Ni content is 3%~10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N.

This type of steel has the characteristics of austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and has significantly improved intergranular corrosion resistance and welding performance, while maintaining iron. The 475°C brittleness and high thermal conductivity of plain stainless steel are characterized by superplasticity.

Compared with austenitic stainless steel, the strength is high and the resistance to intergranular side food and chloride stress corrosion is significantly improved. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel. It is mainly used in the production of acid oil and gas wells.

Difference between butt welding flange with neck and flat welding flange with neck

First, the welding form is different: the welding form of the flanged pipe with a neck is a fillet weld, and the welding weld form of the necked butt welding flange and the pipe is a circular weld;

1: Different materials: The flange material with neck flat welding is processed with thick ordinary steel plates as required, while the flange material with neck butt welding is mainly made of forged steel parts.

2: The nominal pressure is different: the nominal pressure of the neck-welded flange is 0.6 ~ 4.0MPa, and the nominal pressure of the neck-welded flange is 1 ~ 25MPa.

Second, the welds with neck butt welding flanges and pipes belong to category B welds, and the welds with neck flat weld flanges and pipe joints belong to category C welds, and the nondestructive testing after welding is different.
3: The neck flat welding flange and the neck butt welding flange cannot be replaced at will. In terms of manufacturing angle, the neck flat welding flange (SLIPON for short) is large, small in weight, and low in cost. In addition, butt welded flanges with a nominal diameter greater than 250 mm (WN is short for WELDINGNECK) should also be tested at low cost.
