ʻO ka hoʻomaʻamaʻa mua ʻana i nā paipu kila humuhumu pololei: ka hoʻāʻo ʻole ʻana i loko o nā welds. No ka mea, ʻo ka paipu he paipu kila nui loa i ka papahana hoʻolako wai, ʻoi aku ka nui o ka paipu kila me ka mānoanoa o t=30mm i hoʻohana ʻia ma ke ʻano he alahaka paipu. Pono ia e pale i ke kaomi wai o loko a me ka manawa kulou i hana ʻia e ka make o ka paipu kila a me ke kino wai, no laila ke kiʻekiʻe loa nā koi kuʻi. No nā paipu kila nui-diameter me ka mānoanoa o t = 30mm i hoʻohana ʻia i nā alahaka paipu, ʻo nā līlū longitudinal a me nā ʻāpana circumferential he mau welds Class I, e koi ana i ka 100% X-ray film inspection a me 100% wave flaw inspection; ʻoiai no nā paipu kila i kanu ʻia me ka mānoanoa o t=24mm, ʻo nā kuʻi longitudinal no ka Class I welding, a ua lawe ʻia ka 20% X-ray film inspection a me 50% wave flaw detection inspection.

Ka hoʻohana ʻana i nā paipu wili wili pololei: Nui nā ʻano o nā paipu wili wili pololei, e like me ka hoʻohana ʻana: nā paipu welded maʻamau, nā paipu i hoʻoheheʻe ʻia e ka oxygen, nā paipu welded galvanized, nā pahu uwea, nā paipu wili, nā paipu metric welded, nā paipu kaʻa, hohonu. paipu punawai, paipu transformer, paipu wiliwili uwila kūikawā, a me na paipu wiliwili uwila lahilahi.

ʻO nā paipu welded maʻamau: Hoʻohana ʻia nā paipu welded maʻamau no ka lawe ʻana i nā wai haʻahaʻa haʻahaʻa. Hana ʻia me ke kila Q235A, L245, a me Q235B.
ʻO nā paipu kila galvanized: ʻO ia ke uhi ʻana i ka ʻili o ka paipu ʻeleʻele me ka zinc. Ua maheleia i ka wela a me ke anu. He mānoanoa ka papa zinc wela, a he ʻuʻuku ke kumu kūʻai anu.
Oxygen-blown welded pipes: ʻO ka mea maʻamau, he mau paipu kila wili liʻiliʻi lākou, i hoʻohana pinepine ʻia no ka puhi ʻana i ka oxygen.
ʻO nā pahu uea: ʻO ia nā paipu no nā hale hoʻohele, ʻo ia nā paipu kila kalapona wili uila.
ʻO nā paipu pā lahilahi wiliwili uila: He mau paipu anawaena liʻiliʻi i hoʻohana ʻia no nā lako a me nā kukui.
ʻO nā paipu huila: ʻO nā paipu kila i hoʻopaʻa ʻia ma luna o ke kāʻei conveyor e koi i ka ovality.
Nā paipu Transformer: He mau paipu kila kalapona maʻamau. Hoʻohana ʻia e hana i nā paipu hoʻoheheʻe transformer a me nā mea hoʻololi wela ʻē aʻe.
