One, what is fluid canal?

Fluid canal, just as its name implies, it is the pipeline that basically is used at carrying a fluid. It is opposite atStructural canal(basically use at creating rigid structure, bearing bracket) .

On broad sense, all steel tube that carry a fluid can call a fluid the canal. But fall in the words condition of narrow sense and standardization, it points to normally follow specific standard (the GB/T 8163 that be like) make, the seamless steel tube that is used at carrying neuter fluid.

2, the main characteristic of fluid canal

The special canal that before with the structure the canal is mixed, mentions (like cop canal, boiler is in charge of) photograph comparing, fluid canal has its side key:

1. Bear controlling capacity is crucial: Core requirement is can bear surely fluid actuating pressure, guarantee against burst, not leak.

2. Craft is mature, cost economy: Regard general fluid as duct, its material pledges and craft is opposite standard, sexual price is higher.

3. Certain technology asks:

• Hydraulic pressure experiments: Before fluid canal leaves factory, great majority must chase a root to undertake hydraulic pressure experiments, in order to examine its bear press ability and sealing. This is one of distinction with it and structural remarkable canal.

• Inside and outside expresses face quality: Surface of requirement inside and outside is slick, in order to reduce the instruction that the fluid carries, prevent to the knot dirties and be corroded.

Relatively comfortable to high temperature and caustic requirement: Be in charge of photograph comparing with alloy steel tube and stainless steel, standard fluid is in charge of (like 20 steel) apply to without caustic or caustic very weak medium.

3, main standard and material pledge

• Commonly used standard: GB/T 8163" carry a fluid to use seamless steel tube " it is core, commonly used standard.

• Common capable person is qualitative:

• 20# steel (20 steel): This is commonly used, typical fluid canal capable person is qualitative, have good integrated and mechanical performance and technical properties (like solderability, cold curved sex) .

• Q345B (low alloy high strenth steel): Use at the requirement more the circumstance of high strenth.

• If other carbon steel also can be used 10# , 45# according to demand.

4, workmanship

Fluid canal basically is usedSeamless steel tubeCraft is made, be like hot-rolling or cold-drawing. The uniformity that this can assure body and bear the dependability that press. Although also have,solder fluid canal, but in applying with the key in traditional idea, Seamless steel tube is the main aspect that the fluid provides.

5, applied domain

The application that the fluid provides is extremely wide, spread all over each industrial domains and civil domain:

• Hydraulic pressure system: Conduit of the oil cylinder of equipment of production hydraulic pressure, oil path.

• Pneumatic system: Compress air duct to.

• Project machine: The lubricant vitta of of all kinds machinery, cooling conduit.

• Chemical industry: Carry a few without strong caustic industrial chemicals, semifinished product.

• Urban building: Of Lou Yu warm connect air conditioning (HVAC) gush of system, fire control drenchs system.

• General and mechanical equipment: Cooling water is in charge of conduit of path, lubricant system.
