Galvanized steel pipes are divided into hot-dip galvanized steel pipes and pre-galvanized steel pipes, which are welded steel pipes with a galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and extend its service life. Hot dipped galvanized pipes have a wide range of uses, including not only as pipeline pipes for general low-pressure fluids such as water, gas, and oil, but also as oil well pipes and oil transmission pipes for the petroleum industry, especially offshore oil fields, as well as pipes for oil heaters, condensers, coal tar washing oil exchangers in chemical and coking equipment, and for pile pipes in wharves and support frames in mine tunnels. Pre-galvanized pipes have a very small amount of zinc coating, only 20-50g/m2, and their corrosion resistance is much lower than that of hot-dip galvanized pipes. Pre-galvanized pipes cannot be used for water and gas pipelines. The zinc layer of pre-galvanized steel pipes is thin and simply adheres to the steel pipe base, making it prone to peeling off, resulting in poor corrosion resistance. Standard: EN39, ASTM A53, BS1387-85, GB/T3091-08, JIS-G3444, ISO65, BS1139 etc

Galvanized square and rectangular pipes are types of hollow structural tubes which are commonly used in various applications, including: Construction: Galvanized square and rectangular pipes are widely used in the construction industry for structural purposes, such as supports, frames, and trusses. Fencing and Railing: Their durability and corrosion resistance make them a popular choice for fencing and railing systems, providing both security and aesthetics. Greenhouses: The galvanized coating on these pipes makes them ideal for constructing greenhouse frames, as they can withstand exposure to moisture and harsh weather conditions. Signposts and Street Lighting Poles: Galvanized pipes are commonly used for signposts and street lighting installations due to their strength, durability, and resistance to corrosion.

Youfa can supply many types of scaffolding, including ringlock scaffold, frame scaffolding, tube and coupler scaffold, scaffold screw jack, planks for scaffolding, steel props, scaffolding accessories.

Pipe fittings are components used to connect sections of pipes or tubes to divert, control, or change the direction of fluid flow. There are various types of pipe fittings available, including: Elbow: Used to change the direction of a pipe by either 45 degrees or 90 degrees. Tee: Forms a "T" shape, allowing for the connection of three pipes at 90-degree angles. Cross: Similar to a tee, but with an additional outlet, a cross fitting allows for the connection of four pipes. Coupling: Include rigid couplings and flexible couplings. Union: Similar to a coupling, a union fitting allows for easy disconnection and reconnection of pipes. Reducer: Used to connect pipes of different sizes, reducing the diameter of the pipe on one end. Flange: A flat, round jointing surface that allows pipes to be bolted together, commonly used in piping systems to connect sections of pipe, as well as to connect pipe to valves, fittings, or other equipment.

304 and 316 are two different grades of stainless steel, often used for their corrosion resistance in various applications, including pipes. While both grades contain similar basic elements, 316 stainless steel contains additional molybdenum, making it more resistant to corrosion in harsh environments and marine applications.

ERW welding round pipes also are called as Electric Resistance Welded Pipes.This type of steel pipes and tubes are widely used in various fields such as engineering purposes, fencing, scaffolding, line pipes etc. ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.

SSAW (spiral submerged arc welded) steel pipe is a type of spiral welded steel pipe that is commonly used in various applications such as oil and gas transmission, structural support, and water and gas pipelines. The SSAW process involves forming the steel strip into a spiral shape and then welding the seam using a submerged arc welding process. This results in a strong, durable, and cost-effective pipe with good resistance to corrosion and high pressure. SSAW steel pipes are known for their ability to be used in long-distance pipelines and for their suitability for use in harsh and challenging environments.

Grooved ends steel pipes are specifically designed for easy installation and connection in various piping systems. The grooved ends feature a mechanical groove along the pipe's circumference, which allows for quick and secure coupling with compatible fittings, such as grooved couplings or mechanical tees. This type of piping is commonly used in fire protection systems, HVAC, and water distribution applications, offering advantages such as rapid installation, flexibility, and ease of maintenance. The grooved ends eliminate the need for welding, and the assembly process is typically faster compared to traditional systems, making it a popular choice for many piping projects.

Seamless carbon steel pipes are pipes made of carbon steel without any welded seams. They are manufactured using a solid cylindrical billet of carbon steel which is heated and pushed or pulled over a mandrel to form a hollow tube without any seams.
