Preface:
To meet the manufacturing needs of pipeline and oil hydraulic equipment projects for overseas and domestic engineering clients of our group, our company has developed the following auxiliary materials for pipeline eNGINEERING. Specific items are as follows:
I：STAINLESS STEEL & CARBON STEEL FLANGES SERIES
1. Stainless Steel Flanges
A flange is a disc-shaped component, and it is the most common type in pipeline engineering. Flanges are always used in pairs and in conjunction with the matching flanges on valves. In pipeline engineering, flanges are mainly used for connecting pipes. For pipes that need to be connected, install one flange plate on each pipe, add a sealing gasket between the two flange plates, and then tighten them with bolts. Flanges for different pressures have different thicknesses and use different bolts.
Common materials: 304, 316L, 310S, 321.
Products include: PL, SO, WN, BL, SW, TH FLANGES...
Non-standard flanges: Can be custom-made according to customer drawings or requirements.
2. Carbon steel flanges:
The connection components include flanges or end flanges with carbon steel as the main material. Among them, flanges made of carbon steel are called carbon steel flanges. Usually, to prevent rusting, the surface of these flanges is treated with electroplating (such as yellow zinc, white zinc, etc.), or coated with anti-rust oil and painted with anti-rust paint.
Main materials: forged parts A105, or Q235B, 10#, #20 steel, 45# steel, Q345B, etc.
Non-standard flanges: Customizable based on customer drawings and specific requirements.

II. STAINLESS STEEL & CARBON STEEL ELBOW SERIES
1. Stainless Steel Elbow:
In the piping system, the elbow is a pipe fitting that changes the direction of the pipe. According to the angle, there are three most commonly used types: 45°, 90°, and 180°. Additionally, depending on the engineering requirements, there are also other abnormal angle elbows such as 60°. According to its curvature radius, it can be divided into long-radius elbows and short-radius elbows. A long-radius elbow refers to its curvature radius being equal to 1.5 times the outer diameter of the pipe, that is, R = 1.5D. The company always regards customer satisfaction as our ultimate goal of service. We provide various standard elbows as well as various non-standard products, and can customize according to the drawings for customers. We can provide integrated services and purchase the finished products in the shortest time.
Material: 304/316/321/403...
Pressure grade: SCH5S~XXS
2. Carbon Steel Elbow:
The materials: 10#, 20#, A3, Q235A, 20g, Q345B, 20G, 16Mn.
Manufacturing standards: GB/T, ANSI, JIS, DIN, GOST
Bending ratio: 1D/1.5D/2D/2.5D or any specified bending ratio.

Ⅲ. CARBON STEEL & STAINLESS STEEL FLUID ENGINEERING SERIES——TEE, CROSS
Tee (三通): Also called pipe tee, tee fitting or tee joint. Used to split or combine fluid flow in a piping system, installed where the main pipe needs to branch off.
Classified by diameter:
Equal Tee: all three ends of same diameter
Reducing Tee: branch end differs in diameter from run ends
Non-standard / Custom Tee: made to customer drawing or special requirement
Cross / Four-way Tee (四通): A four-end pipe fitting allowing flow in four directions (usually two straight runs + two perpendicular branches).
Classified as:
Equal Cross
Reducing Cross
Non-standard / Custom Cross
Our company can provide customized manufacturing according to customer's drawings and requirements.

IV. STAINLESS STEEL VALVE SERIES
With the sustained economic growth, the valve industry has become one of the fundamental industries of the national economy. Valves play a vital role in oil & gas, chemical, power plant, metallurgy, pharmaceutical and long-distance pipeline projects. Energy saving and resource conservation are now urgent issues for heavy industry. Manufacturers are upgrading existing facilities and replacing outdated, energy-intensive and polluting equipment. To bring the valve industry to a higher level, environmentally friendly products and optimized product structures are increasingly required, which demands a large number of technologically advanced valve products. Energy-efficient valves have significant market potential.
Valves are used to control the flow of various fluids: air, water, steam, corrosive media, slurry, oil, liquid metals and radioactive media. Based on material, valves are classified into: cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.). Common types include: butterfly valve, gate valve, globe valve, stainless steel ball valve, 3-piece quick-assembly ball valve, ANSI standard ball valve, etc.
Customizable according to customer requirements.
