pe热熔管件焊接原理是待焊接的管材(件)两个端面以一定压力靠在一个预热好温度的热板上维持一定时间。当卷边高度达标后，调低压力进行吸热阶段。当吸热时间完成后，取出加热板，给待焊两端面施压，使两个焊接面紧密接触，直至冷却完成，最终两个端面粘接在一起。
pe管件分类方法
1.管件依根据施工方法、用途不同分：电熔管件和热熔管件。
2.热熔管件根据生产方式分：注塑管件和焊制管件(不推荐使用)。
3.热熔管件有法兰、变径、弯头、等径三通、异径三通和端帽等
4.电熔管件有套筒、变径、弯头、三通、鞍型三通、鞍型端帽
热熔管件搬运摆放要求
1.户外堆放应有遮盖物，不应直接被阳光照射。
2.应堆放在平整的地面或支撑物上。
3.管材搬运、吊装时应采用非金属绳或带。
4.应小心轻放、严禁抛摔和拖拽
热熔对接标准要求
1.热熔对接管件的PE级别及SDR应与管材的PE级别及SDR相同。
2.颜色对兼容性无影响。
3.不同PE级别、不同SDR的管材/管件不应使用热容对接。
4.高密度PE80管材/管件与中密度PE80管材/管件不宜热熔对接。
5.加热板表面温度：该工艺推荐温度为200～235℃，施工时根据施工环境和材料可适当进行调整。
SDR11管 材:PE80=210±10℃ PE100=225±10℃
SDR17.6管材:PE80=210±10℃ PE100=225±10℃[1]
Shandong Wanji Plastic Co., Ltd.
1.10 are produced by Battenfeld and Cincinnati, German: They can produce caliber 20mm-450mm pipes. Our advanced extrusion equipment not only ensures the full plasticization of raw materials, but also effectively prevents the excessive shear degradation of raw materials in the extrusion process, and fully exerts the performance of the raw materials, far higher than the national standards. It has created good conditions for the smooth construction of the pipe.
2. Imported online automatic measurement system and ultrasonic on-line detection device: Each of the company's PE pipe production line equipment is equipped with Innomax online weight control and wall-thickness measurement system, which truly guarantees the consistency of the wall thickness of the pipe.
3. Italian Baiwang raw material dehumidifying and drying system: the Company uses Italian Baiwang dehumidifying dryer, the best brand in the world, which quickly takes away the moisture from plastic raw materials. Eliminates the creation of air bubbles, enabling the product to achieve ideal mechanical, electrical, dimensional stability and appearance. Dehumidifier dryer air pipes are sealed circulatory system, and equipped with filters, so outside climate, in summer of high ambient humidity can be normal production, effectively prevent the production of defective products, greatly reduce the production of waste, and increase productivity.
4. Company's pipe fittings production: our company has 19 injection-molding equipment, that can produce 20mm-1200mm various pipe fittings. Among them, the largest injection-molding machine in China designed and manufactured by Zhejiang Tairui Machinery Co., Ltd. for our company. The maximum clamping force is 2800T, the maximum injection volume is 120,000 grams, and the injection molding diameter dn800mm is molded once. The quality has reached the international level. The level of the product. At present, the company's production of PE pipe has reached more than 600 kinds, fully complete series of supporting production.
