Qual é a temperatura de soldagem do tubo PE?

2025-08-19

Como um tubo de plástico amplamente utilizado no abastecimento de água e drenagem, transporte de gás e outros campos, a qualidade da soldagem do tubo de PE está diretamente relacionada à segurança e vida útil de todo o sistema de tubulação. Como um parâmetro chave no processo de soldagem, a temperatura de soldagem é um dos elementos principais para garantir que a interface seja firme e livre de vazamentos.

Em circunstâncias normais, a temperatura de soldagem do tubo de PE varia de acordo com seu grau de matéria-prima e características específicas do produto. Para tubos PE comuns de graus PE80 e PE100, a temperatura de soldagem recomendada é geralmente entre 200 ° C e 230 ° C. Na operação real, essa faixa de temperatura precisa ser estritamente controlada. Se a temperatura for muito alta, pode levar à carbonização e degradação da superfície de soldagem do tubo, o que afeta a resistência da soldagem e o desempenho da vedação; se a temperatura for muito baixa, pode causar soldagem insuficiente e a interface está sujeita a vazamentos.

Além da temperatura de soldagem, tempo de aquecimento, pressão de topo e outros parâmetros são igualmente importantes, eles juntos constituem um sistema de processo de soldagem completo. Como fabricante profissional de tubos, a AD Pipe sempre enfatiza a importância da construção padronizada. Recomenda-se que, ao soldar o tubo AD PE, consulte o manual do produto ou as especificações técnicas relevantes, combinadas com o diâmetro do tubo, espessura da parede e outros fatores para definir parâmetros de soldagem razoáveis. Ao mesmo tempo, para usar o padrão do equipamento de soldagem por fusão a quente e para garantir que o equipamento esteja funcionando normalmente, a placa de aquecimento limpa.

Antes da soldagem, a porta do tubo deve ser limpa e moldada para remover a camada de óxido e as impurezas, para garantir que a superfície da extremidade seja plana. Durante o processo de soldagem, o operador precisa ter habilidades profissionais, prestar muita atenção às mudanças de temperatura e ao processo de soldagem, para garantir a qualidade da soldagem. Após a conclusão da soldagem, ela precisa ser resfriada de acordo com os regulamentos para evitar interferências externas. Depois que a interface for completamente resfriada e solidificada, a construção de acompanhamento pode ser realizada.

Em suma, compreender com precisão a temperatura de soldagem e os requisitos de processo relacionados dos tubos PE é a base para garantir a operação estável a longo prazo do sistema de dutos. Selecionar produtos de tubos PE com qualidade confiável, como tubos AD, e seguir estritamente o processo de soldagem científico pode efetivamente evitar riscos de engenharia causados por soldagem inadequada e fornecer proteção sólida de dutos para vários projetos de transporte de fluidos.
