Below is some questions you may want to know:

Questions: How can we know the chemical component of your products is according to our request?

Answers: When we offer samples or batch parts, we will also send you our material list from our material factory, it shows more detailed.

Questions: How to guarantee your final size can meet our drawing request?

Answers: we will make moulds according to your 3D drawing. And we also do sampling when batch production start, to make assure the final dimension can meet your request.

Questions: How to make sure the color after painting or powder coating can be correct?

Answers: We have color card with different color number, such as RAL9016, we will contrast the sample surface and color card, to make sure the final surface effect is correct.

Questions: Generally, how do you packing the goods?

Answers: normally, for inner package: the goods is nude, for outer package: carton + plywood. If you have special request for inner or outer package, pls indicate it when you send us new inquiry.

Questions: If we find the defect products exist in the batch parts, how to do?

Answers: Yes,your caution is very good, in fact, when batch production, we need do sampling. Before shipment, we also do testing to make sure the quality is ok. If you found several defect product exists, pls take photos and send your quality feedback, we will check and send you quality products. But pls be assured that our products is qualified, unless caused by the worker's mistake to place.

The steel tube has a hollow section, and its length is much larger than that of the steel with diameter or circumference.
They are divided into circular, square, rectangular and special-shaped steel tubes according to the section shape.
The material is divided into carbon structural Steel Pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe.
It is divided into pipeline, engineering structure, thermal equipment, petrochemical industry, mechanical manufacturing, geological drilling, and high pressure equipment for use.

According to the production process, it is divided into Seamless Steel Pipe and welded pipe, of which two kinds of seamless steel pipe are hot rolling and cold rolling (drawing). The welded pipe is divided into straight seam welded pipe and spiral seam welded pipe.

Steel pipe is not only used for transporting fluid and powdery solid, exchanging heat energy, manufacturing mechanical parts and containers, but also an economic steel. The use of steel pipe to build structural grid, pillar and mechanical support can reduce weight, save metal 20 to 40%, and realize mechanized construction in factories. The manufacture of road and bridge with steel pipe can not only save steel products and simplify construction, but also greatly reduce the area of protective coating and save investment and maintenance costs.

According to the production method, the steel pipe can be divided into two main categories: seamless steel pipe and slotted steel pipe.

1, seamless steel tubes can be divided into hot rolled seamless pipes, cold drawn tubes, precision steel pipes, hot expansion pipes, cold spinning pipes and extruded pipes according to the production methods.

Seamless steel tubes are made of high quality carbon steel or alloy steel, and are divided into hot rolling and cold rolling (drawing).

2, welded pipes are divided into furnace pipe, electric welding (resistance welding) tube and automatic arc welding pipe because of its different welding technology. Because of its different welding forms, there are two kinds of welded pipe and spiral welded pipe, and the end shape is divided into circular welded pipe and special type (square, flat, etc.) welded pipe.

The welded steel pipe is made of the rolled tube shaped steel plate, which is welded by the seam or spiral seam. In the manufacturing method, it is divided into the welded pipe of low pressure fluid transportation, the spiral seam welded pipe, the direct coil welding pipe, the welding pipe and so on. Seamless steel pipe can be used in various industries such as liquid pressure pipes and gas pipes. Welded pipes can be used for water conveyance pipelines, gas pipes, heating pipes, electrical appliances pipes, etc.
