On August 6, we received a new inquiry from a Vietnamese customer, which mainly involved carbon steel butt weld pipe fittings and flanges, such as butt welding stub-end, flanges, elbows, half couplings, end caps, and hex plugs. The specified materials include A105, P245GH, P265GH, A182 F304, A234 WPB, and CS. The specifications cover various pressure ratings, sizes, and standards, including ASME, EN, and ISO. They offer high temperature, corrosion, and high-pressure resistance, making them suitable for use in industries such as oil, chemical, and power, especially in severe environments. After providing the customer with a quote, they were highly satisfied with our competitive pricing and timely delivery, and they subsequently placed an order with us. Below are the details of the order.

From the purchase order, we can see that one of the main products available for purchase is ASTM A105 Butt Welding Stub End. Let’s take a closer look at the ASTM A105 Butt Welding Stub End. A lap joint stub end is a type of steel butt weld fitting, typically used as a component in loose flanges. Loose flanges are commonly used in situations where the medium has low temperature and pressure but strong corrosiveness.
