Capillary pipe Stainless
Capillary stainless steel tubes are different corrosion resistance, mechanical strength, biological inertness and durability. High chemical resistance of such tubes can be used in aggressive environments. Complex alloys, that contain the molybdenum, nickel, chromium, silicon differ greatest resistance. Depending on the operating conditions selected alloy brand with the desired set of properties.
Production of capillary tubes
The normalized GOST 14 162−79. Commonly used 12X18H10T steel. From carbon and alloy steel pipe produced heat — and cold-deformed (GOST 21 729−76). It comes capillary tube is soft and work-hardened in coils and of a certain length (off-gauge and dimensional) on request.
Along the length of the pipe produce
|Marking length||Length||allowable maximum deviation over the entire length|
|off-gage||more than 300 mm|
|measuring||4000 mm||15 mm|
|dimensional fold||to 4000 mm with allowance for each time 5 mm||15 mm|
|in riots||up to 160 m|
At the request of dimensional and multiple dimensional pipes are made no longer than 7 m.
Standardize tube — outside diameter and wall thickness.
|External diameter||Standardization||Allowable diameter deviation|
|Over 0.6 mm||internal diameter and wall thickness||and 0.01 mm outer diameter deviation limit.|
|Over 0.6 mm||the outer and inner diameters|
|Less than 0.6 mm||the inner and outer diameters||1. bunks. diameter — increased accuracy 2 wall thickness — the usual precision. 3. The one-way maximum deviation on the bunks. diameter and wall thickness|
|Less than 0.6 mm||internal diameter and wall thickness||1. bunks. diameter — increased accuracy 2 wall thickness — the usual precision. 3. The one-way maximum deviation on the bunks. diameter and wall thickness|
The value of one-sided limit deviation is permissible within the limits of the amount of the maximum deviation. It can be ordered with an internal diameter tube, excluding the maximum wall thickness deviations, and the outer diameter. The curvature of the tube should not exceed 3 mm per 1 m. Upon request, the handset comes with no changes. No standard: the curvature of the tube with an outer diameter of 1 mm and a tube received in coils or in the cold-worked state, the tube should be free of sharp bends.
