Welding blanket for plumbing had been designed to protect surfaces, walls and surrounding objects during the welding process of copper tubes in plumbing works. Thanks to its double layer of WELD SX fabric, this Texfire’s blankets performs as a thermal barriers, isolating heat caused by the blowing torch’s flame. The flame retardant features of this fabric are inherent, meaning that they do not decrease either with use or wear.

Texfire’s welding blanket for plumbing is composed by an E-glass fibreglass nucleus, special silicone for high temperatures and carbonized plush.

This multi-layered confers the blanket some mechanical resistance and the ability to perform as a thermal barrier, being able to resist temperatures peaks up to 1400ªC (the maximum temperature of the plumbing torch) and, also, thanks to its thermal insulator feature, it achieves a notable reduction of the heat transference between both sides of the blanket.

Texfire produces and sells this plumbing blanket in two different sizes; 35x25 cm y 50x35 cm, both with a 4 mm thickness. It can be used on both sides, plus it is flexible and light, allowing its easy placement between the copper tubes or any other reduced area where the blowing torch is going to be used.

When installing it, it is recommended to do it in order that the blowing torch’s flame points to the centre of the blanket, avoiding this way the edges or sews. It cannot be washed nor vacuumed.

WELD SX fabric, used to tailor the welding blankets for plumbing, is certified in 2020 with regulation UNE 23727 - Reaction to fire of building materials - achieving an M2 classification. It also meets regulation EN ISO 9150 with a Class 2 classification - Behaviour of materials before the impact of small melted metal splashes.

I used this with a mapp torch to sweat a copper fitting to a bathtub spout. I had to get up against the wall of a cultured marble bathtub to braze the fitting. I put this mat against the wall and heated the fitting frequently directing the flame onto the mat protecting the wall. When I finished I checked the bathtub wall for any heat damage, and not only was there no damage the wall was not even warm. This mat was well worth the price for what it saved me in potential heat damage. Highly recommended.
