304 STAINLESS STEEL CAPILLARY TUBING

304 STAINLESS STEEL CAPILLARY TUBING,
,

Stainless steel seamless square tubing, It’s a hollow strip of steel called a square pipe because its cross section is square. A large number of pipeline used for conveying fluid, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsion strength at the same time, lighter weight, so also widely used in manufacturing machinery parts and engineering structures

Stainless steel square tube classification: square tube is divided into seamless steel tube and welded steel tube (seam pipe) two categories. According to section shape can be divided into square and rectangular tube, widely used is circular steel tube, but there are some semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped steel tube.

For stainless steel square tube under fluid pressure to carry out hydraulic test to test its pressure capacity and quality, under the specified pressure does not leak, wet or expansion for qualified, some steel pipe according to the standard or the requirements of the side of the roll test, flaring test, flattening test.

Square tube specifications: 5*5~150*150 mm thickness :0.4~ 6.0mm

Square tube material: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S

Stainless Steel Seamless Square Tubing, The Production Process

Round steel preparation → heating → hot rolling perforation → cutting head → pickling → polishing → lubrication → cold rolling process → degreasing → solution heat treatment → straightening → pipe cutting → pickling → finished product inspection.

Stainless Steel Seamless Square Tubing ，Performance Analysis

The metal can react with oxygen in the atmosphere to form an oxide film on the surface. The iron oxide formed on ordinary carbon steel will continue to oxidize, expanding the corrosion and eventually forming holes. This can be done using paint or an oxidation-resistant metal plating to protect the surface of carbon steel, but this coating is only a thin film. If the coating is damaged, the steel underneath begins to rust again. Whether the stainless steel tube is corroded is related to the chromium content in the steel. When the chromium content in the steel reaches 12%, the surface of the stainless steel tube generates a layer of passivation and dense chromium rich oxide to protect the surface and prevent further reoxidation. This oxide layer is extremely thin, through which the natural sheen of the steel surface can be seen, giving stainless steel a unique surface. If the chromium film is damaged once, the chromium in the steel and the oxygen in the atmosphere to regenerate the passivation film, continue to play a protective role. In some special environments, stainless steel will also appear some local corrosion and failure, but stainless steel and carbon steel is different, will not appear uniform corrosion and failure, so the corrosion allowance for stainless steel tube is meaningless.

Stainless steel capillary, stainless steel small tube is widely used in medical treatment, fiber-optic, pen making, electronic welding products, light cable joint, food, vintage, dairy, drink, pharmacy and biochemistry, different length can be provided according to requests

Capillary tubes with a maximum bore of 0.0158 in., available in a wide range of stainless steels. Sandvik capillary tubes are characterized by tight tolerances, and the inside surface of the tubes is free from oil, grease and other particles. This ensures, for example, an optimized and even flow of liquids and gases from the sensor to the measuring instrument.

Stainless steel Coiled tubing is available in a range of different product forms depending on the customer requirements. Licancheng sihe stainless steel material manufactures welded and seamless tube products. The standard grades are 304 304L 316L(UNS S31603) Duplex 2205 (UNS S32205 & S31803) Super Duplex 2507 (UNS S32750) Incoloy 825 (UNS N08825) Inconel 625 (UNS N06625) Other grades of stainless steel in duplex and superduplex and nickel alloy are available on request.

Diameter from 3mm (0.118’’) to 25.4mm (1.00’’) OD. Wall thickness from 0.5mm (0.020’’) to 3mm (0.118’’).Tubing can be supplied in the annealed or cold worked stainless steel control line pipe condition.
