Stainless steel capillary pipe of HDT is charactrized by excellent corrosion resistance, precision dimensions, and the inside surface free from grease, oil and other particles, which ensures optimized and even flow in the piping:

1) Steel grades:
Capillary tube of HDT is available in a wide range of stainless steel grades and duplex stainless steel grades in AISI, EN/DIN, JIS, GOST standards.
AISI: 304/304L, 316 /316L, 321/321H, 316Ti, 347 / 347H; S31803, 2205
EN/DIN: 1.4301/1.4307, 1.4401/4404, 1.4541/1.4878, 1.4571, 1.4462

2) Size range:
Outside diameter: 0.1 mm to 8 mm;
WT: 0.05 mm to 2.1mm.
Length: Capillary tubing is supplied in fixed straight lengths (mostly 6 meters), or in coil as seamless coiled tubing.

3) Delivery conditon:
Stainless steel capillary tube usually is delivered in bright annealed condition, for ensuring the inside surface without oil, grease. However, capillary tubing in annealed and pickled condition is also available on customer's requirments.

4) Advantages:
Capillary tube / capillary pipe in stainless steel have many advantages as:
- High corrosion resistance;
- Smooth inside surface without grease and oil;
- High precision tolerances
- Durable in use.

5) Application:
Stainless capillary tubing is widely used in many industrial applications, such as:
- Precision instruments and appartus
- Liquid and gas lines
- Electronic&electric applications
- Automatic apparatus

Precision Stainless Steel Pipe for us means stainless capillary tubes. It is steel pipe of small internal diameter; used in refrigeration as a control for the flow of liquid refrigerant or as an expansion device between the condenser and evaporator; or used to transmit pressure from the sensitive bulb of a temperature control to the operating element.
