The situation of flanged steel pipe fittings before and after packaging is typically as follows: Before Packaging: 1. Cleaning and Inspection: Prior to packaging, flanged steel pipe fittings are usually cleaned and inspected to ensure that their surfaces are free from significant dirt, corrosion, or damage. 2. Protective Measures: If the surfaces of the fittings […]

Flanges are usually coated with a layer of anti-rust oil before leaving the factory, which is to protect the surface of the flange from oxidation and corrosion. Anti-rust oil can form a protective layer to block the metal surface of the flange from contact with moisture and oxygen in the air, thereby reducing the oxidation […]

Copper-nickel flanges have the following characteristics: 1. Strong Corrosion Resistance: Copper-nickel alloys exhibit excellent resistance to corrosion, especially in seawater, acidic, and alkaline environments. This makes copper-nickel flanges suitable for applications in marine engineering, chemical industries, petroleum, and fertilizers. 2. High-Temperature Stability: Copper-nickel alloys generally possess good high-temperature stability, allowing them to maintain their mechanical […]

A flange is a metal product mostly used to install steel pipe fittings, usually in a cement environment. It is an essential component of indoor plumbing equipment such as water pipes, air conditioners, and heating. It can connect them well to play the role of waterproof and dustproof, which greatly prolongs the service life. The […]

Here are the steps to be taken before shipping flanges: 1. Order Verification: Ensure that the order details are accurate, including the number of goods, model specifications, packaging requirements, shipping address, etc. 2. Goods Inspection: Inspect the goods before shipping to ensure their quality and specifications meet the customer’s requirements and standards. This helps avoid […]

Flange testing typically refers to the process of inspecting the tightness, sealing, and pressure resistance performance of flange connections. Flanges are a common type of pipe connection used to join different components, equipment, or pipelines to enable the flow of fluids or gases between them. Flange testing generally covers the following aspects: 1. Tightness Testing: This […]

In construction, chemical industry, energy, shipbuilding and other industries, flanged pipe fittings, as a key component of the pipeline system, play an important role in connecting and fixing various pipe sections, equipment and valves. Flange fittings play an irreplaceable role in modern society due to their high sealing performance and pressure resistance. Therefore, understanding the […]

Non-destructive testing of flange fittings is a method used to inspect the connections of piping systems, aiming to detect potential defects, cracks, corrosion, and other issues without the need for dismantling or destructive testing of the pipeline. This helps to ensure the safety, stability, and efficient operation of the piping system. Here are common non-destructive […]

Manufacturing and Inspection Process of Flanges: Flanges are essential components used to connect pipes, valves, and equipment, ensuring secure connections and seals. The manufacturing and inspection process of flanges is crucial. Below is an overview of the general steps involved: Flange Manufacturing Process:1. Material Selection: Choose suitable materials, typically including carbon steel, stainless steel, alloy […]

A Vernier caliper is used as a tool to measure flange connections in flange testing. Flange connections are commonly used for joining pipes, valves, pumps, and other equipment to ensure sealing and safety. In flange testing, it is essential to inspect parameters such as flatness, irregularities, and roundness of the flange contact surfaces to ensure […]
