Gas pipelines
Gas pipeline sealing and corrosion protection, when the consequences of failure are different
In a gas pipeline, the consequences of failure are on another level entirely from district heating. For gas lines Kampek supplies Covalence steel-pipe heat‑shrink sleeves (the HTLP and WPC ranges, repair patches, epoxy and application accessories) and Stopaq systems, from urban distribution to long‑distance transport pipelines. The district heating RJS‑E, FOPS and DHEC are not gas products.
Choose this when the joint is on pre‑insulated pipe and the sizes vary: the sleeve is wrapped on site and covers casings from 90 to 1200 mm, including repairs and dimensions outside a standard series.
Choose this when the surface is bare steel or an irregular shape: bends, valves, flanges, tanks, and corrosion under insulation. ST2 cleaning is enough, no blasting is needed, and it works as prevention as much as repair.
Products for gas lines
Covalence's steel‑pipe line: girth‑weld shrink sleeves, epoxy, closure patches, tape for bends and coating repair products. Stopaq for fittings and crossings.
WPCP‑IV
Closure patch for Covalence wrap‑around heat‑shrink sleeves.
Perp Melt Stick
Heat‑melted PE copolymer stick for repairing small surface scratches in a PE coating where the damage does not reach the steel.
HTLP60‑DCS
Wrap‑around heat‑shrink sleeve for the girth welds of steel pipe on gas and other transmission lines.
Dirax
Fibre‑glass reinforced wrap‑around heat‑shrink sleeve for horizontal directional drilling.
S1301‑M epoksi
Solvent‑free two‑component epoxy primer for Covalence three‑layer systems (HTLP60‑DCS, HTLP80, DIRAX) on steel pipe girth welds.
Flexclad‑II‑C30
Stretchable, hand‑wrapped heat‑shrink tape for corrosion protection of pipe bends and small‑diameter straight pipe in distribution networks.
S1137 mastic filler tape
High‑viscosity sealant‑based mastic tape used to fill damaged coating before a repair patch or sleeve goes on, restoring the original coating thickness.
Questions and answers
What protects buried gas pipes and steel lines?
Can Stopaq be applied without taking the pipe out of service?
Does the protection interfere with cathodic protection?
What temperature and load does the protection withstand?
Does the system also suit crossings and casings?
