Надувной контейнер для бурения нефтяных скважин с инжектором

Introduction:

Producing in various kinds of specification the high pressure packers, the intergral element in maintenance and repair of water stop and cracks of concrete structures and automated production lines enable not just the cost reduction but manufacture of goods of uniform quality. In particular, it offers excellent function in is especially backdraft damper in terms of durability and low-ciscostly resin and designed to be used in installing packers and finishing job.

Advantage:
1It is possible to force a large amount of resin at a high speed, which ensures the through injection.
2 Because back water check valves are installed on bolt areas, it is possible, irrespective of the hardening of resin, to snap the severde parts of the nuts immediately after the injection work is completed.

LangWei is a fast growing international manufacturer of construction chemicals with plants in Beijing, China. The company is specialized in preventative and remedial waterproofing products.

Preventative waterproofing products are wildly used during new construction and are usually installed by the general contractor.Examples are bentonite strips, hydrophilic mastics and rubbers, which swell in contact with water and hence block water ingress,injection hoses, which can be injected at a later stage to block water and finally cementitious coatings for basement waterproofing and elastomeric membranes for tanks and roofs.

Remedial waterproofing products are mostly used when major (or minor) water leaks happen at a later stage and are usually applied by specialist applicators. Remedial waterproofing products are also often used during construction of tunnels and other underground constructions to prevent infiltrating water from hindering the normal progress of the works. Examples are injection resins based on Polyurethanes (both 1C and 2C) and Poly-acrylates. These products are also used for Soil and Rock Stabilization,together with Organo-minerals.

LangWei also manufactures a series of products for the Protection and Repair of reinforced

Concrete. Examples are cementitious grouts and mortars, epoxy injection resins, carbon fibre laminates and epoxy glues.
