The stainless steel coil pipe is a specialized form of stainless steel tubing that is coiled into a compact spiral shape. This design allows for greater flexibility and is particularly useful in applications where space is limited or where tubing needs to be routed through tight or curved spaces.
WUXI KONGZO STEEL is a leading stainless steel coil supplier, offering the best price and service. We can process orders to any specification, length, and thickness, and then do quality inspection and packaging.

Stainless steel coil pipes find applications in a range of industries and uses, including:
1、Heat Exchangers: Used as heat exchange tubing in applications where efficient heat transfer is required, such as in refrigeration, HVAC systems, and chemical processes.
2、Instrumentation: Employed in analytical and process instrumentation, including chromatography, analytical instruments, and medical equipment.
3、Oil and Gas: Used in the oil and gas industry for downhole and surface applications, including control lines, chemical injection lines, and hydraulic lines.
4、Hydraulic and Pneumatic Systems: Utilized in hydraulic and pneumatic systems where flexibility is needed to route tubing through complex machinery and equipment.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat, rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process, the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
