304L stainless steel tube

Spec. :Sch5s-sch80s

OD：10-1200mm W.T: 0.6-10mm

Application: ornamental
Standard: ASTM A269/A270/A554/A312
Delivery Time: 15-25 days

Packing: wooden box/PVC bag/nest loading

304L has oxidation resistance to a maximum temperature of 1650° F (899° C) continuously without appreciable scaling. The maximum temperature for intermittent exposure is 1500° F (816° C). Since 304L is an extra low-carbon variation of 304 it can often be used in the “as-welded” condition (without annealing), even in severe corrosive conditions, except for applications specifying stress relief.

304L has good welding characteristics and can be welded by all standard methods but attention needs to be paid to avoid weld “hot cracking”. Welding may be followed by annealing to relieve stresses during severe forming or spinning.

Stainless Steel Heat Exchanger Pipe (ASTM A249/A269 EN10217-7)

Heat Exchanger stainless pipe

Key Points：

Crystal Structure

All of our heat exchanger pipes will follow the ASTM A269 standard， annealing 1050 ℃ will get the most even structure. Great improvement of plasticity before bending will be available.

Customizable Sizes

OD: 12mm-159mm

W.T: 0.6mm-3.05mm

Customized Length: 6m, 20 feet, or as required

Professional Tests

Inspections include the testing of water pressure, eddy current, flare test, and intergranular corrosion test will be applied.

Heat Exchanger stainless pipe Application

Stainless steel Sanitary tube

Outside Diameter: 24mm-159mm
Thickness: 0.6mm-3.05mm
Length: 6m, 20 feet or as required
Finish: 180/240/320Grit (Rɑ 0.5-0.8µm)

Precise polishing

We expertised in surface polishing craftsmanship. Stainless steel pipe surface grit ranges from 180G to 320G (Rɑ 0.8µm and Rɑ 0.5µm) standard. Customized polishing is availble.

Hot rolled/cold rolled

most of stainless steel pipe are made from hot rolled strip, however, we can supply cold rolled pipe strips, and the chemical and mechanical property are more stable, and ensure easy welding.

Stable structure

Annealing temperature controlled to 1,038°C, which can make the pipe more ductile and easily get bended without crack.

Stainless Steel Ornamental and Construction Pipe (ASTM A554 EN10296-2)

Stainless A554 pipe is widely used in decoration and construction. It is supposed to be the most widely used pipe in our daily life. For the surface polishing, Based on grit， there are 180#，320#，380#， based on surface shining， there are matte polished and mirror shining polished. Based on mode type, there are round/square/rectangular/customized modes. Customized shap also available.

Advantage of our Manual welding pipe

Better Raw Material

Most of material are from first class mills like Baosteel, Posco, Tsingshan. From slitting to material test, we provide the best chemical and mechanical guarantee.
