In fact, the sanitary grade stainless steel 304 material is almost the same in every house. It mainly depends on various aspects of management.
Sanitary stainless steel welded pipe (welded sanitary stainless steel pipe, stainless steel internal flattened welded pipe)
Welded sanitary stainless steel pipe production process:
Sanitary welded pipe ( Pipe blank) production process: steel coil - slitting and slitting - forming - automatic welding - external weld grinding - internal weld bead leveling - (online solution treatment/online bright annealing) - eddy current flaw detection - cooling to certain diameter - end trimming Flat end and flying saw cutting
The cut stainless steel welded pipe undergoes the following three processes:
(1) The welded pipe is straightened, flattened, water pressure, inspected, packaged and put into storage. (Welding industrial pipe blank process);
(2) The heat-treated welded pipe undergoes degreasing, bright heat treatment, straightening, ultrasonic flaw detection, flat head, water pressure, inspection, packaging and storage (seamless chemical industrial welded pipe Process);
(3) The polished welded pipe is degreased, internally polished, externally polished, inspected, packaged and put into storage (sanitary welded pipe production process);
Sanitary welded pipes are in stock Inventory management
1. The length of the spot inventory of sanitary grade welded pipes is 6 meters
2. The spot inventory held is about 300 tons
3. All the spot stocks kept are Sanitary stainless steel pipes polished inside and outside, packed in woven bags
4. Implementation standard: "GB/T12771-2008 Stainless steel welded steel pipes for fluid transportation"
Keep in stock common specifications:
Sanitary welded pipe applications:
A) Pharmaceutical catheters, food fluid pipes, beer delivery pipes, drinking water, beverages and other industries
B) Bioengineering fluid pipes , chemical engineering, medical engineering ducts, auto parts ducts
C) Air purification transportation, aviation, seawater desalination equipment ducts, etc.
D) Food machinery factory, engine factory, chemical machinery factory , refrigeration machinery factory, etc.
E) Medical machinery equipment manufacturing factory, hydraulic equipment factory, vacuum equipment factory, etc.
F) Ultra-high purity gas equipment and manipulator cylinder block. Pneumatic components, Cylinder liners, electric heating appliances
G) Sanitary welded pipes are mainly used as fluid pipes or high-end decorative pipes for products.
Special characteristics of sanitary welded pipes
The product itself is non-magnetic, has uniform wall thickness, high precision, smooth inner wall, no pitting, and good quality. Internal leveling, internal polishing, metal smoothness ≤0.2-0.4μm, can be finely polished with 600 mesh inside and outside
If you have special requirements for the pipe, customers can request the corresponding samples, and we will try our best to provide them. Relevant specifications, and we also hope that customers will come and visit the factory.
Packaging and transportation characteristics of sanitary-grade welded pipes:
A) Sanitary-grade welded pipes need to be packed in plastic film bags after internal and external polishing
B) The pipe mouth requires a plastic pipe cap Cover to protect both ends of the pipe during transportation
C) Bundle with cloth strips to prevent loose transportation
D) Bundle and package in woven bags, and wrap the outside of the woven bags with tape Above
E) Special color markings are used during transportation, and the outer surface is clearly written to prevent extrusion
