Specifications

1, rubber hose size measurement: inner and outer diameter and enhancement layer outer diameter, wall thickness, concentricity, inner and outer glue layer thickness, diameter combination, new GB and ISO increased length and the measuring point sign, the provisions of the pipe joint and a variety of tube joint of the hose length measurement method.
2, hydraulic test to verify the pressure test: the test hose and composite parts in the verification of the pressure continued to produce leakage, deformation and damage 30s-60s. Pressure deformation test: under the provisions of the pressure (pressure test pressure or other less than the test pressure of the pressure) for 1 minute, measuring hose length and diameter change and torsion angle and the bending. Bursting pressure test: the pressure at the time when the pressure is controlled by the pressure of the tube under the condition of the required speed. Leak test: under the minimum burst pressure of 70% of the static pressure to save 5min, repeated, check whether leakage or damage. Because the test is often used in water, and the viscosity of the actual use of the liquid, the pressure and the temperature of the test may be slightly lower pressure.
3, low temperature bending test at low temperature rigid: hose clamp to in diameter for 12 times the tube diameter of torsional wheel, at low temperatures parking 6 hours after, in the 12s reversed 180 degrees when the measured torque and standard temperature measured under the torque ratio. Low temperature bending: hose clamp in diameter 12 times the diameter of the pipe diameter, after 24 hours in the 10s to reverse the 180 degrees, check inside and outside the plastic is brittle fracture and damage. Test of low temperature brittleness of the most simple measuring hose is the sample at low temperature bending 90 degrees, or after a period of frozen hose compression 1 / 2 to see if the brittle fracture, and a method is with a certain weight of the weight of the free falling and impact test specimens to see whether the specimen embrittlement.
4, bending test: the tube bending to a certain extent, the measurement of the minimum diameter of the bending part and the ratio of the diameter of the front, the ball through the ability and the bending force in the tube.
5, suction flat test: in the 1min vacuum, to maintain the 10min, with a diameter of 0.9 times the diameter of the pipe diameter of the ball rolled over, check the pipe collapse degree. Some standards used to measure the diameter of the hose to indicate the extent of hose deformation.
6, the interlayer bonding strength test: automotive rubber hose multi diameter less than 50mm braided hose, test common width 10mm or 25mm long specimen, using 25mm wide ring, a 90 degree peel, tensile speed 25mm/min.

Steam hose

Steam hose

Steam hose
The definition of steam hose generally has the following parameters:
Pressure
General working pressure in the 7 bar, the higher the burst pressure can reach 70 bar
Temperature
Common temperature range in -30 ~+130, some of the imported hose can even reach +210
Resistance
Common resistance coefficient is less than 109.
Diameter and wall thickness
Diameter and diameter of hose, wall thickness often refers to the thickness of the inner diameter, outer diameter refers to the largest external circle.
The parameters of a high pressure steam pipe are as follows.
Inner diameter (mm) wall thickness (mm) outside diameter (mm)
13625
32.5 196.75
39.5 257.25

360 Spiral steel pipe

360 Spiral steel pipe

360 Spiral steel pipe
(1) the raw material, the strip coil, the welding wire, and the flux. In the input before the strict physical and chemical test.
(2) strip head and tail docking, using single or double wire submerged arc welding, the steel tube rolled by automatic submerged arc welding welding.
(3) before forming the strip, the strip is treated with a flat, cutting edge, a plane, and a surface cleaning and conveying and bending.
(4) using the electric contact pressure gauge to control the pressure of the pressure cylinder on the two sides of the conveyor to ensure the smooth delivery of the strip.
(5) the use of external control or internal control roll forming.
(6) the use of the weld gap control device to ensure that the weld gap to meet the requirements of welding, pipe diameter, the wrong side of the weld gap and the strict control.
(7) welding and welding using the Lincoln Electric welding machine for single or double wire submerged arc welding, so as to obtain a stable welding quality.
(8) the welded seam is examined by an on-line continuous ultrasonic automatic ultrasonic instrument, which can ensure that the coverage rate of 100% of the non destructive testing of the weld seam is covered. If there are defects, automatic alarm and spray marking, the production workers and so at any time to adjust the process parameters, the timely elimination of defects.
(9) the air plasma cutting machine to cut a single pipe.
(10) into a single tube, each batch of steel tube to strict inspection system first, check the weld mechanical properties, chemical composition, blending, surface quality of the pipe and after nondestructive inspection, to ensure that the pipe manufacturing technology qualified, can be formally put into production.
(11) weld continuous acoustic inspection mark the site, after manual ultrasonic and X-ray review, if indeed defects, after repair again after testing until it is confirmed the defects have been eliminated.
(12) strip butt weld and intersecting and spiral seam D connector tube, all through X ray TV or film examination.
(13) the hydrostatic pressure test is used for each pipe, and the pressure is sealed by a radial seal. The test pressure and time are strictly controlled by the microcomputer detecting device of the steel pipe. Test parameters automatic print record.
(14) the pipe end machining, the end verticality, can accurately control the slope angle and blunt edge.
