YI、HBTCG-16型管材与管件耐拉拔试验仪简介：
HBTCG-16型管材与管件耐拉拔试验仪满足GB/T 15820聚乙烯压力管材与管件的连接耐拉拔试验，适用于直径不大于 63 mm的聚乙烯(PE)压力管材与不同材质，不同结构形式的管件的连 接，不适用于熔焊连接 。
Brief introduction of hbtcg-16 type pipe ａnd pipe fittings tensile resistance tester:
Hbtcg-16 type pipe ａnd pipe fittings tensile resistance tester meets the requirements of gb/t 15820 polyethylene pressure pipe ａnd pipe fittings connection ａnd drawing resistance test. It is applicable to the connection between polyethylene (PE) pressure pipe with diameter not more than 63 mm ａnd different materials ａnd different structure forms of pipe fittings, ａnd is not suitable for fusion welding connection.
二、HBTCG-16型管材与管件耐拉拔试验仪结构原理：
检验聚乙烯压力管材与管件连接后承受纵向拉力时的耐拉拔能力。
三、HBTCG-16型管材与管件耐拉拔试验仪主要技术指标：
1、恒载施力：20N-5000N
2、测试工位：1个
3、杠杆比例：1:10
4、试验管材尺寸范围：DN16-DN63
5、外形尺寸：1200*450*1200mm
6、整机重量：120Kg
四、HBTCG-16型管材与管件耐拉拔试验仪试验方法：
1、试样由管件与或二段聚乙烯管材组装而成，每段管材长度至少为 300 mm。管材尺寸应与管件 相配，并按产品说明书的要求组装。
2、试样数量为三件，试验温度为23士2C. 调试仪器至工作状态。
3、测童管材内径的大值、小值，取算术平均值;测量管材外径的大值、小值，取算术平均值 用下列公式计算试验所需要的力K:
K=15×α×π÷4 ×（d1-d）
式中:a－－聚乙烯管材的允许设计应力;
D1— 管材平均外径，mm;
d— 管材平均内径，mm
K值取小数点后位数字。
4、将试样固定在拉力计上(或悬挂于框架上)，在30 s内逐渐施加到计算的力K，保持试样在恒定的 纵向拉力1h，检查试样连接处是否松脱
5、试验结果 在三件试样中，试样连接处均未松脱，则认为通过试验。
Test method of hbtcg-16 tube ａnd fitting drawing resistance tester:
1. The sample is assembled by pipe fitting ａnd one or two sections of polyethylene pipe, ａnd each section of pipe is at least 300 mm in length. The pipe size should match the pipe fitting ａnd be assembled according to the requirements of the product specification.
2. The number of samples is three, ａnd the test temperature is 23 ± 2C.
3. Measure the maximum ａnd minimum values of the inner diameter of the pipe, ａnd take the arithmetic mean value; measure the maximum ａnd minimum values of the outer diameter of the pipe, ａnd take the arithmetic mean value. Use the following formula to calculate the force K required for the test:
K=15×α×π÷4 ×（d1-d）
Where: a －－ allowable design stress of polyethylene pipe;
D1 - average outer diameter of pipe, mm;
D-average inner diameter of pipe, mm
The value of K is one significant digit after the decimal point.
4. Fix the sample on the tension meter (or hang it on the frame), gradually apply the calculated force K within 30 s, keep the sample in a constant longitudinal tension for 1 h, ａnd check whether the joint of the sample is loose
5. The test results show that the joint of the three samples is not loose, so it is considered to pass the test.
