Detection Method of Horizontal Vulcanization Tank
Subject Content and Scope of Application
This standard specifies the detection methods of the main items of horizontal vulcanization tanks. This standard is applicable to the detection of horizontal vulcanization tanks. This standard is used in conjunction with the HG2265 "Horizontal Vulcanization Tank" product standard. 2 Main detection items and detection methods
Detection items
Temperature difference in the working area of ​​the tank under pressure
Detection method
Hang the thermometer at the measuring point position shown in Figure 1. After maintaining the pressure for 20 minutes at the rated steam pressure, record the temperature difference between the upper and lower parts of the indirect heated vulcanizer at each measuring point. Calculate the difference between the arithmetic mean of the temperatures of the two measuring points at the upper part of each section and the arithmetic mean of the temperatures of the two measuring points at the lower part. This value is the temperature difference between the upper and lower parts of the section. Take the larger temperature value of the three sections as the temperature difference between the upper and lower parts of the tank: b. Temperature difference at both ends of the tank. Calculate the difference between the arithmetic mean of the temperatures of the 5 measuring points in the front section and the arithmetic mean of the temperatures of the 5 measuring points in the rear section, and take this value as the temperature difference at both ends of the tank.
2 Directly heated vulcanizing tank
Calculate the average temperature of each
measuring point in each section of the figure respectively, and take the difference between the maximum and minimum values ​​of the three average values ​​as the temperature difference value of the inner working area

: For circumferential welds, take the main product end face of the welding shuttle test ruler
as the measurement base surface, and measure in cooperation with the goniometer (Figure 2-2).
The scale value of the main scale part aligned with the goniometer scale is the misalignment of the circumferential weld
Use the sample shown in Figure 3-1,
For the protruding correction angle, use the inner sample with the same outer arc radius as the inner circle radius of the measured cylinder close to the inner surface of the cylinder (Figure

Reinforcement height of Class B weld
Testing method
HG/T2113-91
The reinforcement height of longitudinal welds shall be measured with the sample shown in Figure 6-1. For the longitudinal seams on the outer surface of the cylinder, the outer sample with the same diameter shall be tightly attached to the weld in turn. || On the arc surface of the parent material on both sides of the weld, the distances e” and e” from the top of the weld to the circular strength surfaces of the parent material on both sides of the weld are obtained by a movable ruler (Figure 6-2). The larger value is taken as the residual height of the longitudinal weld on the outer surface of the cylinder. For the residual height of the longitudinal weld on the inner surface of the cylinder, the outer arc semi-light and the inner semi-light of the cylinder to be measured are aligned with the inner arc semi-light: the inner sample is measured according to the above method (Figure 6-2).

For the circumferential coal seams on the inner and outer surfaces of the cylinder, the main scale end faces of the welding inspection ruler are pressed against the parent material surfaces on both sides of the weld in turn, and the distance from the top of the weld to the parent material surfaces on both sides of the weld is measured by movable ruler 1, and the e" value (Figure 6-3) is taken as the residual height of the circumferential weld.

Use an inner diameter ruler to measure the oxygen tank in the shape of a "M".
Body. The inner diameter values ​​at four places on the surface of the tank are as follows: the difference between the maximum inner diameter D and the reduced inner diameter Dm is the roundness error of a single section (Figure 7): along the length of the tank body, measure the roundness error of each section (and at least measure the front, middle and rear sections of the entire length), and take the larger one as the roundness error of the tank body: 2 External diameter measurement method: Use a caliper to measure the vertical quotient of the tank body on the ground according to the above method.At 5

away from the autoclave horizontally. Use a sound level meter to measure the background noise of each measuring point and the noise A during the operation of the vulcanizer according to the marked points
as shown in Figure 8, and correct them according to the background noise margin values ​​listed in the following table:
Background noise margin value table
The A sound level measured during operation is different from the background noise level A sound level. The noise correction value K should be removed. The measurement is invalid. The average sound pressure level on the wing disc surface is expressed as: 101g[-] The average sound pressure level on the measured surface is dB (the standard value is 20 μPa);

Take the average A sound level LpA
of the measuring surface as the noise value during the vulcanization operation. When the value variation range of
(LeA-K,) does not exceed 5dB, the arithmetic mean of the corrected A
sound level of each measuring point can be taken as the noise value during the vulcanization operation
.
If the difference between the A sound level
(before correction) of two adjacent measuring points exceeds 5dB (A), an additional point should be added between the two measuring points
