Slip-on raised Face Flange is commonly used in piping systems, where the bolt-hole flange bolt hole pattern slips over the pipe’s end and welds in place. These flanges are available in various sizes and designs to meet the specific demands of the application. In this blog, we will break down everything you need to know

Why are boiler pipes so important? Imagine: In the dead of winter, the wind is biting. If a factory production line is forced to stop due to a boiler pipe leak, it will result in tens of thousands of losses per hour. In the home, the heating system has no heating due to pipe corrosion

Why Tee Pipe is the core component of industrial pipeline system ‌ In the complex industrial pipeline network, there is a hub node connecting three directions, which is the tee pipe. It is the core accessory for diversion and confluence in the pipeline system, affecting the efficiency and overall safety of transportation. According to the

Comparison Dimensions Galvanized pipe Black steel pipe ‌Anti-corrosion mechanism‌ Sacrificial anode protection (zinc layer preferentially oxidized) Reliance on iron oxide passivation layer ‌Salt spray life‌ 2000 hours without red rust Red rust appears after 72 hours ‌Coating Thickness‌ 80-120μm (hot dip galvanized) No coating, oxide layer ≤ 5μm ‌Initial Cost‌ ¥42.8/m (including galvanizing process) ¥28.5/m

Why is carbon steel the “universal material” of industry? Carbon steel is an alloy material whose main raw materials are iron and carbon. Carbon steel accounts for more than 90% of the global steel usage. Due to its low cost, high strength and easy processing, it has become the first choice in the fields of

Regarding marine applications, the material used for pipes is of utmost importance. Pipes that can withstand the harsh saltwater environment, high pressure, and extreme temperatures are necessary for smooth operations in the marine industry. One such material that has been gaining popularity for marine pipes is SMO 254. In this blog post, we delve deeper

‌Basic formula for pipe weight The weight calculation of pipelines is a crucial step in engineering design, and its accuracy will directly affect the safety and cost control of the entire structure. Empty tube weight calculation The general formula for empty tube weight (WpWp​) is: Wp=π4×ρm×(do2−di2)Wp​=4π​×ρm​×(do2​−di2​) ‌Parameter Description‌do​: Pipe outer diameter (unit: meter)di​: Pipe inner

Shale gas horizontal well: Shale gas horizontal well is complicated and has serious wear on drill pipe, so EU type drill pipe should be used, because the outer layer of this drill pipe has been specially treated with wear resistance, and has a wear-resistant layer that can withstand more than 200 times of casing wear.

In the ASTM B36.10M standard, pipe is defined as “a fluid transport carrier based on the nominal pipe diameter (NPS), which proves that pipe is mainly based on its fluid transport capacity and its compatibility with other piping systems. In ASTM A249, tube emphasizes “a structural hollow body with precise size control”. The definition clearly highlights

1. Convenient socket alignment (easy alignment, no spot welding required) 2. Low risk of leakage (reduced leakage caused by loose connection parts) 3. Control of weld metal flow (metal will not flow into the tube hole) 4. Reduced installation cost (loose size requirements, no need for complex high-level processing) 1. The importance of expansion gap
