Capillary tube stainless
Dignity
Stainless steel capillary pipes have a high corrosion resistance, mechanical strength, biological inertness, durability. Chemical resistance allows the use of such pipes in a rather aggressive environments. The greatest resistance have complex alloyed alloys containing a high percentage of Nickel, copper, molybdenum and silicon. Grade with the necessary set of qualities is chosen dependent on the concentration of the aggressive factor, temperature, and other conditions.
Production
The capillary tube is usually made of steel 12X18H10T according to GOST 14162−79. The manufacture of pipes of warm and cold-normalizes GOST 21729−76. Capillary stainless steel tube is hard and soft. Are supplied a certain length (measured, unmeasured) or in rolls upon agreement with the customer.
The length of the pipe produced:
| Length marking | Length, mm | the maximum allowable deviation in length |
|---|---|---|
| dimensional | Not more than 4000 | ±15 mm |
| random | Over 300 | |
| dimensional | 4,000 with an allowance of 5 mm on each time | ±15 mm |
| in the bays | No more than 160 meters |
At the request of the customer dimensional and dimensional pipes are manufactured in length not exceeding 7 metres.
Standartisied tube wall thickness, outer diameter.
| Standardization | External diameter, mm | Allowable deviation of diameter |
|---|---|---|
wall thickness, inner diameter for inner, outer diameter |
above 0.6 | Outside diameter, tolerance is up to 0.01 mm. |
| for inner, outer diameter | Not more than 0.6 | -outer diameter — increased accuracy -wall thickness — standard precision. — with extreme unilateral deviation in wall thickness, outside diameter |
The value of the maximum unilateral deviation allowed within the boundaries of the sum of limit deviations. But you can specify parameters for wall thickness, inner or outer diameter excluding extreme deviations. Not allowed curvature of the tube segment with a length of 1 meter, greater than 3 mm. On request these tube comes without editing, and if its outer diameter to 1 mm, the curvature is not normalized as well as the curvature of the products supplied by revolts or cold-worked condition. However, articles should be no sharp kinks.
